For nylon and TPU, a filament dryer needs more than a sealed box: useful temperature control and even heat matter when moisture can spoil a print. My best overall pick is the SUNLU S4, which stands out for its support for nylon and TPU and capacity for multiple spools. The Creality Space Pi SE Pro 2.0 is a strong alternative for its circulating hot air, while the Polymaker PolyDryer suits buyers who put sealed storage first. The main tradeoffs are spool capacity, drying temperature, and whether you want active drying, storage, or both. Read on for the full breakdown and help matching a dryer to your materials and printing habits.

Key Takeaways
- The SUNLU S4 models stand apart for multi-spool flexibility; both listed versions name nylon and TPU support, making them the clearest fit for drying several material types or spools.
- Circulating heat is a meaningful differentiator: the Creality Space Pi SE Pro 2.0 explicitly lists 360° hot-air circulation, while many other listings give less detail about airflow.
- Single-spool dryers favor simpler setups: several Creality Space Pi and SUNLU S2 options are aimed at one spool, so they may suit occasional drying better than a multi-printer workflow.
- Drying and storage are different jobs: the Polymaker PolyDryer is framed around storage as well as drying, a useful distinction for buyers who want to keep filament protected between prints.
- Product names and specs need careful checking: this lineup includes near-duplicate SUNLU and Comgrow models, and some listings specify TPU or nylon while others name only common materials.

More Details on Our Top Picks
SUNLU Official Filament Dryer S2, for PLA PETG ABS Filament, Black
For a nylon or TPU user who wants clear controls rather than a large multi-spool cabinet, the SUNLU S2 offers an approachable setup: its 4.6-inch touch display provides temperature, humidity, and time controls, while 360° heating with dual heating sheets and a fan is intended to distribute warmth around the spool. Its maximum of 70°C gives it a useful range for many common drying jobs, though buyers should follow the filament maker’s temperature guidance, especially with nylon. Compared with the SUNLU S4, this unit handles a more modest spool load, but takes up less room and avoids paying for four-spool capacity. The tradeoff is that the listed title emphasizes PLA, PETG, and ABS, so nylon and TPU buyers should verify compatibility and settings before choosing it; 70°C may also be insufficient for some drying routines.
Pros:- 360° heating system combines dual heating sheets with a fan for more even warmth.
- Large 4.6-inch touch screen makes temperature, humidity, and time settings accessible.
- Supports a range of filament types and sizes according to the product description.
- One-key operation and an LED indicator simplify routine use.
Cons:- Maximum temperature of 70°C may not meet every nylon drying recommendation.
- The product title focuses on PLA, PETG, and ABS, so nylon and TPU suitability should be checked rather than assumed.
- Its 3.3-pound body and stated spool capacity require dedicated workspace.
Best for: Single-spool users who want a touch-screen dryer with straightforward temperature and timer controls and have confirmed their nylon or TPU settings fit its range.
Not ideal for: Owners drying several spools at once, or nylon users whose filament maker specifies temperatures above 70°C.
- Brand:SUNLU
- Model:SUNLU 3D Printer Filament Dryer S2
- Color:Black
- Maximum temperature:Up to 70°C
- Maximum capacity:210 × 85 mm
- Heating:360° system with dual heating sheets and fan
- Display:4.6-inch LCD touch screen
- Weight:3.3 pounds
Our verdict“Choose this S2 for guided, single-spool drying if its 70°C ceiling matches your filament’s instructions; pick the SUNLU S4 instead for multiple spools.”
Sovol Filament Dryer SH01 – Filament Dehydrator and Spool Holder for 3D Printers
The Sovol SH01 earns its place for buyers who want to dry more than one spool without moving up to the four-spool SUNLU S4. Its chamber fits two rolls narrower than 70 mm or one roll narrower than 150 mm, and live temperature and humidity monitoring helps users track the drying environment. For nylon and TPU, the main limitation is the fixed set of just 40°C, 45°C, and 50°C; that is less flexible than the Creality Space Pi’s adjustable 45–70°C range, and may not suit every filament maker’s instructions. The built-in fan supports even heating, but the SH01 calls for opening its PTFE seals during heating so moisture can escape, and it does not include desiccants. Buyers in cooler rooms should also account for the stated performance caveat below 16°C.
Pros:- Fits two spools under 70 mm wide or one spool under 150 mm wide.
- Real-time temperature and humidity monitoring gives users visibility into chamber conditions.
- Built-in fan is designed to circulate heat evenly.
- Lists TPU among compatible materials.
Cons:- Temperature choices stop at 50°C, limiting its usefulness for some nylon drying instructions.
- PTFE seals need to be opened during heating to let moisture escape.
- Desiccants are not included, and performance may vary in rooms below 16°C.
Best for: Makers who rotate between two narrow spools or one wider spool and want live humidity monitoring at a modest set of temperatures.
Not ideal for: Nylon users needing higher drying temperatures, or anyone seeking a sealed, low-intervention drying and storage setup.
- Model:SV-SH01-1
- Spool capacity:Two rolls under 70 mm wide or one roll under 150 mm wide
- Temperature settings:40°C, 45°C, and 50°C
- Humidity monitoring:Yes
- Power-off drying mode:Yes
- Listed compatible materials:PETG, PLA, PTFE, and TPU
- Weight:1.4 kg
- Spool-width guidance:Up to 70 mm for two rolls; up to 150 mm for one roll
Our verdict“Choose the SH01 for monitored two-spool drying when its 40–50°C settings suit your filament, but favor the Creality Space Pi for a wider temperature range.”
SUNLU Official Filament Dryer S4, for Nylon TPU PLA PETG ABS, (White)
When a job calls for several rolls of nylon or TPU to be ready together, the SUNLU S4 makes a stronger case than the single-spool Creality Space Pi: its interior holds four 1 kg spools, which can reduce the need to dry rolls in separate batches or keep multiple printers waiting. The stated 70°C maximum and 350W PTC heater provide the headline drying capability, and the product explicitly names both nylon and TPU among its compatible materials. That capacity comes with a real footprint: the interior measures 450 × 210 × 211 mm, so it is better suited to a dedicated workbench than a cramped printer shelf. Buyers should also check their material makers’ temperature recommendations; a 70°C ceiling will not cover every nylon routine. Compared with the Sovol SH01, the S4 trades lower spool capacity and simpler temperature options for substantially more simultaneous feed capacity.
Pros:- Four-spool capacity supports simultaneous drying and feeding for several printers or multi-color work.
- Product description explicitly lists nylon and TPU compatibility.
- Heats up to 70°C with a 350W PTC heater.
- Interior dimensions are provided for checking spool fit before purchase.
Cons:- Large interior and four-spool format take more workspace than the Creality Space Pi or smaller SUNLU S2.
- The 70°C maximum may fall short of some nylon drying instructions.
- The supplied product data does not specify display, humidity monitoring, or a timer.
Best for: Multi-printer owners and makers running multi-color jobs who need to dry up to four 1 kg nylon or TPU spools together.
Not ideal for: Single-spool users with limited bench space, or nylon users whose filament instructions call for temperatures above 70°C.
- Brand:SUNLU
- Color:White
- Capacity:Four 1 kg spools
- Interior dimensions:450 × 210 × 211 mm
- Maximum temperature:70°C
- Heater:350W PTC heater
- Compatible filament diameters:1.75 mm, 2.85 mm, and 3.0 mm
- Weight:4.8 kg
Our verdict“Pick the S4 when simultaneous four-spool nylon or TPU drying matters more than compact size or detailed control specifications.”
Creality Space Pi Filament Dryer, Filament Storage Box
The Creality Space Pi suits nylon and TPU owners who value adjustable settings more than high spool capacity. Its 45–70°C range gives more temperature choices than the Sovol SH01’s three settings, while the 0–48-hour timer supports longer drying cycles without relying on manual timing. A 360° hot-air circulation system and PTC heater are designed to spread heat around the filament, and the memory function can restore settings after a power interruption. Against the four-spool SUNLU S4, this is the more focused option: it lists common filament diameters but does not claim multi-spool capacity, and its 5 kg weight makes it less convenient to move than the product’s compact-sounding format might suggest. The description also says it is for drying, not storage, so it is not a sealed long-term home for moisture-sensitive nylon.
Pros:- 45–70°C range offers more temperature flexibility than the Sovol SH01.
- 0–48-hour timer can support extended drying schedules.
- 360° hot-air circulation and a PTC heater are designed for uniform heating.
- Memory function resumes settings after power outages.
Cons:- No multi-spool capacity is specified, unlike the four-spool SUNLU S4.
- At 5 kg, it is relatively heavy for users who need to move the dryer often.
- The product data says it is not intended for filament storage.
Best for: Single-spool users who want a timer, adjustable heat, and power-outage setting memory for nylon or TPU drying cycles.
Not ideal for: Makers who need to dry multiple spools together or keep filament sealed for long-term storage after drying.
- Power:80W
- Heating technology:PTC heater
- Temperature range:45°C–70°C
- Compatible filament diameters:1.75 mm, 2.85 mm, and 3 mm
- Timer:0–48 hours
- Display:3.7-inch LCD touch screen
- Weight:5 kg
- Heating circulation:360° hot-air circulation
Our verdict“Choose the Space Pi for adjustable, timed single-spool drying, but select the SUNLU S4 if you need several rolls ready at once.”
SUNLU Filament Dryer S2, Black
The earlier SUNLU Filament Dryer S2 is the practical pick for owners who want to feed filament to a printer while drying it, rather than dry a spool and transfer it later. Its listed capacity of 265 × 274 × 118 mm and support for 1.75 mm, 2.85 mm, and 3.00 mm filament sizes make it broadly useful across common setups, while the touch screen allows customizable settings. Like the newer SUNLU S2 in this roundup, it tops out at 70°C, so neither is a fit for every nylon drying instruction; the newer S2 description gives more detail about 360° heating and its 4.6-inch display. Compared with the Creality Space Pi, this model is lighter at 1.51 kg, but its product data does not specify a timer range or heater wattage. It is a convenience-focused dryer, not a substitute for checking material-specific settings.
Pros:- Can dry filament during printing, reducing spool handling between drying and use.
- Compatible with 1.75 mm, 2.85 mm, and 3.00 mm filament sizes.
- Touch-screen controls support customizable operation.
- At 1.51 kg, it is lighter than the 5 kg Creality Space Pi.
Cons:- 70°C maximum may not match every nylon drying recommendation.
- Requires an external power source during operation.
- The supplied specs do not state timer range, heater power, or humidity monitoring.
Best for: Printer owners who want a lightweight dryer that can feed filament during a print and accept common spool filament diameters.
Not ideal for: Nylon users needing temperatures above 70°C or buyers who want specified timer, heater, or humidity-monitoring details.
- Maximum temperature:70°C
- Capacity dimensions:265 × 274 × 118 mm
- Compatible filament sizes:1.75 mm, 2.85 mm, and 3.00 mm
- Material:Plastic
- Weight:1.51 kg
- Controls:Touch screen with customizable settings
- Use during printing:Designed to dry filament while printing
Our verdict“Choose this S2 for lightweight, in-use filament drying if 70°C is sufficient; the Creality Space Pi is better documented for timer and temperature control.”
SUNLU Filament Dryer Box S1 Plus, Black
I’d choose the SUNLU S1 Plus for a straightforward drying setup where a readable display matters more than high heat. Its 35–55°C range and fan-assisted drying suit buyers who want adjustable control for everyday filament, but that ceiling is a limitation for nylon: it offers less temperature headroom than the Creality Space Pi SE, which reaches 65°C. The LCD shows temperature, humidity, and time, making it easier to keep track of a drying cycle than a basic box with fewer visible settings. It supports several filament diameters, though the listed capacity is a single-spool dimension rather than a two-spool setup like the Comgrow SH01. I’d treat it as a general-purpose dryer, not a dedicated choice for moisture-sensitive nylon that calls for higher drying temperatures.
Pros:- Fan-assisted drying helps circulate warm air around the filament.
- LCD displays temperature, humidity, and time.
- Adjustable temperature and drying time offer more control than a fixed-setting box.
- Supports 1.75 mm, 2.85 mm, and 3.00 mm filament.
Cons:- The 55°C maximum is restrictive for nylon-focused drying.
- The listed capacity dimensions do not indicate room for multiple spools.
- Requires a power source and is less suited to portable use.
Best for: Makers who mostly dry common filament and want an LCD to monitor temperature, humidity, and time.
Not ideal for: Nylon users who need a dryer with more temperature headroom than 55°C, or anyone seeking a multi-spool unit.
- Temperature range:35°C–55°C
- Filament compatibility:1.75 mm, 2.85 mm, and 3.00 mm
- Maximum capacity dimensions:210 × 89 mm
- Display:LCD for temperature, humidity, and time
- Additional feature:Fan design
- Material:Polyethylene terephthalate glycol
- Weight:1.2 kg
- Color:Black
Our verdict“Choose the S1 Plus for visible controls and everyday filament drying, but pick a higher-temperature dryer for regular nylon work.”
Comgrow SH01 3D Printer Filament Dryer Box – Storage and Dehydrator for 1.75mm/2.85mm PLA PETG ABS
The Comgrow SH01 fills a different need from the single-spool Creality Space Pi SE: it can hold two 1 kg spools, so I’d shortlist it for a workshop that wants to dry or store more filament at once. The LCD reports temperature and humidity, and the timer can be set from six to twelve hours. Its 40–50°C range, however, leaves little headroom for nylon and is lower than the SUNLU S1 Plus’s 55°C ceiling, let alone the Creality dryer’s 65°C. Its stated compatible materials are PLA, ABS, PETG, and silk, so the listing does not establish nylon or TPU support. The sealed design and spool capacity are useful for general storage, but I would skip it for nylon-first drying or if uninterrupted long cycles are a priority; the product data also notes an idle auto-shutoff.
Pros:- Holds up to two 1 kg spools.
- LCD displays temperature and humidity during operation.
- Adjustable drying time from 6 to 12 hours.
- Silicone cable sheath and Teflon tube with plug support a sealed setup.
Cons:- The 50°C maximum is a poor fit for nylon-focused drying.
- Listed material compatibility does not include nylon or TPU.
- An idle auto-shutoff and confusing setup instructions may complicate operation.
Best for: Makers who want a two-spool dryer and storage box for PLA, ABS, PETG, or silk filament.
Not ideal for: Nylon or TPU users seeking explicit material compatibility and higher drying temperatures, or users who need long cycles without interruption.
- Capacity:Up to 2 × 1 kg spools
- Inner dimensions:9.29 × 6.49 × 9.13 inches
- Temperature range:40°C–50°C
- Drying time setting:6–12 hours
- Display:2-inch LCD with touch buttons
- Listed compatible materials:PLA, ABS, PETG, and silk
- Filament diameters:1.75 mm and 2.85 mm
- Sealing features:Silicone cable sheath and Teflon tube with plug
Our verdict“Pick the SH01 for two-spool PLA, PETG, or ABS storage and drying, not for a nylon-and-TPU-centered setup.”
SUNLU Filament Dryer S2 Plus, 70°C Max Temperature, Built-in Circulation Fan, 3D Printer Filament Storage Box, Dehydrator, White
For buyers comparing SUNLU’s lower-temperature S1 Plus with a more capable dryer, the S2 Plus stands out with a 70°C maximum. That gives it more temperature headroom for nylon than the S1 Plus’s 55°C limit or the Comgrow SH01’s 50°C ceiling, making it the stronger SUNLU fit for tougher drying needs. A built-in circulation fan and touch screen are intended to support even heating and straightforward adjustment, while the stated capacity dimensions accommodate a range of filament sizes. The tradeoff is that its product data does not specify a drying timer range or list compatible materials, so I’d verify the desired nylon or TPU spool and cycle requirements before buying. It is also a powered, relatively large box; the Creality Space Pi SE may suit buyers who want a more explicitly documented 1 kg setup.
Pros:- 70°C maximum offers more temperature headroom than the SUNLU S1 Plus and Comgrow SH01.
- Built-in circulation fan is designed to distribute heat more evenly.
- Touch screen supports temperature and time adjustments.
- Capacity dimensions are listed for checking spool fit.
Cons:- The supplied product data does not name supported materials or give a spool weight capacity.
- No drying-time range is provided in the listed specifications.
- Requires power and may take up substantial workspace.
Best for: SUNLU buyers who need higher temperature headroom and a touch interface for drying nylon or other demanding filament.
Not ideal for: Shoppers who need clearly stated spool capacity, material compatibility, or drying-time settings before choosing a unit.
- Maximum temperature:70°C
- Capacity dimensions:265 × 274 × 118 mm
- Compatible filament sizes:1.75 mm, 2.85 mm, and 3.00 mm
- Heating feature:Built-in circulation fan
- Controls:Touch screen for temperature and time adjustments
- Material:High-impact polystyrene
- Weight:1.19 kg
- Color:White
Our verdict“Choose the S2 Plus when SUNLU branding and a 70°C ceiling matter most, after confirming its capacity and cycle settings fit your spools.”
Creality 2026 Upgrade Filament Dryer Box Pro, Space Pi SE with High PTC Efficiency & Precision Sensor for 1KG Spools
I’d rank the Creality Space Pi SE above lower-temperature boxes like the Comgrow SH01 for buyers who need a more useful range for moisture-sensitive filament. Its 45–65°C adjustment and timer of up to 24 hours allow a longer, tailored cycle, while the built-in fan and thermal insulation are designed to spread heat around a 1 kg spool. Real-time humidity monitoring adds useful feedback beyond simply setting a temperature and waiting. The 65°C ceiling is still below the SUNLU S2 Plus’s listed 70°C, so buyers needing that extra headroom should compare those models carefully. This listing names TPU among compatible materials but does not explicitly name nylon, and it specifies 1 kg spools only. I’d choose it for monitored, adjustable drying; I would not assume it suits larger spools or every nylon routine.
Pros:- Adjustable 45°C–65°C temperature range offers more control than the Comgrow SH01.
- Timer supports cycles from 0 to 24 hours.
- Real-time humidity monitoring helps users follow drying conditions.
- Built-in fan and thermal insulation are designed for quick, even heating.
Cons:- Capacity is limited to 1 kg spools.
- The 65°C maximum is below the SUNLU S2 Plus’s listed 70°C ceiling.
- The supplied listing does not explicitly name nylon compatibility.
Best for: Makers drying 1 kg spools who want a long adjustable cycle, humidity monitoring, and explicit TPU compatibility.
Not ideal for: Users with larger spools or those who require a dryer listing explicit nylon compatibility and a temperature above 65°C.
- Temperature range:45°C–65°C
- Drying time:0–24 hours
- Spool capacity:1 kg
- Filament diameters:1.75 mm and 2.85 mm
- Listed compatibility:PLA, PETG, ABS, and TPU
- Input voltage:110 V, 50/60 Hz
- Monitoring:Real-time humidity monitoring
- Warranty:6 months
Our verdict“Choose the Space Pi SE for monitored, long-cycle drying of 1 kg spools, especially when TPU support is a priority.”
Creality Filament Dryer Box Pro 2.0 with Fans, Space Pi SE Upgraded 360° Hot‑Air 65°C PTC Circulating Heating, 1 kg Dehydrator for 1.75/2.85 mm PLA PETG ABS TPU Nylon
The Creality Space Pi SE Upgraded is the most directly targeted option here for users who want to dry nylon or TPU while a print is running. Its listing explicitly names both materials, and the dual rollers let filament feed through during drying—an advantage over the SUNLU S2 Plus, whose supplied data does not describe printing while the spool is inside. The 360° hot-air system is specified to reach 65°C in about 15 minutes, with a 45–65°C range and timer up to 24 hours. That makes cycle control clearer than the Comgrow SH01’s 40–50°C range. Its 65°C ceiling is still lower than the SUNLU S2 Plus’s 70°C, and capacity is limited to one 1 kg spool. I’d choose it for active printing and named nylon/TPU support, not for multi-spool drying or app-based control.
Pros:- Explicitly lists nylon and TPU among compatible materials.
- Dual rollers allow printing while the filament is drying.
- 360° hot-air circulation is specified to reach 65°C in about 15 minutes.
- LCD controls temperature and drying time, with cycles up to 24 hours.
Cons:- Holds only one 1 kg spool.
- The 65°C maximum is lower than the SUNLU S2 Plus’s 70°C ceiling.
- No wireless or app control; settings require manual adjustment.
Best for: Nylon and TPU users who want a 1 kg spool drying while filament feeds directly to the printer.
Not ideal for: Makers who need to dry multiple spools at once, want app control, or need a maximum temperature above 65°C.
- Temperature range:45°C–65°C
- Maximum heating time:24 hours
- Heating system:360° hot-air circulation with PTC heating
- Heating time:Reaches 65°C in about 15 minutes
- Filament capacity:1 kg
- Supported filament diameters:1.75 mm and 2.85 mm
- Compatible materials:PLA, PETG, ABS, TPU, ASA, PP, PC, PA, and nylon
- Dimensions:266 × 237 × 99 mm
Our verdict“Pick this Space Pi SE version for one-spool nylon or TPU jobs that need drying and printing at the same time.”
SUNLU Official Filament Dryer S4, for Nylon TPU PLA PETG ABS, Black
For a workshop drying several moisture-sensitive spools at once, the SUNLU S4’s four-spool capacity is its clearest advantage. Its 70°C maximum temperature and three fans make it better suited to batch drying than the single-spool Creality Space PI, while the listed compatibility with nylon and TPU keeps it relevant to this roundup. The tradeoff is scale: at 10.56 pounds and with a 450 × 210 × 211 mm interior, it takes more bench space than a compact dryer. It is a dryer, not a sealed storage solution, so filament may need separate protection after the cycle. I’d choose it for varied, high-throughput printing; for one spool at a time, the smaller Creality is easier to accommodate.
Pros:- Holds four 1 kg spools for batch drying
- Reaches a stated maximum of 70°C
- Three fans support heat circulation across the larger interior
- Supports 1.75 mm, 2.85 mm, and 3.0 mm filament
Cons:- Large footprint and 10.56-pound weight can limit placement
- Provides drying rather than sealed long-term storage
Best for: Makers who regularly dry multiple nylon or TPU spools and have dedicated bench space.
Not ideal for: Single-spool users or cramped workspaces where a four-spool unit would be oversized.
- Capacity:4 spools, 1 kg each
- Interior dimensions:450 × 210 × 211 mm
- Maximum temperature:70°C
- Heater power:350 W
- Fans:3
- Filament diameters:1.75 mm, 2.85 mm, 3.0 mm
- Weight:10.56 lb
Our verdict“Choose the SUNLU S4 if drying several nylon or TPU spools together matters more than saving workspace.”
Comgrow Filament Dryer Box, SH02 Dry Box Filament Sealed Storage Box 3D Printer 2 Spools Holder with PTC Fast Heater, Touch Screen
The Comgrow SH02 suits users who want to dry two spools and feed filament onward without moving them to another holder. Its 40–70°C range and presets for nine material types include PA nylon and TPU, which makes setup more approachable than choosing every setting manually. The listing also describes a sealed enclosure and two feed holes, adding moisture protection during printing that the SUNLU S4 does not emphasize. Its 150 W heater is less powerful on paper than the S4’s 350 W unit, and the SH02’s two-spool limit makes it a smaller-batch choice. I’d pick it over the Polymaker storage-only box when active heating is needed, but skip it if you need to dry more than two rolls at once.
Pros:- Dries two 1 kg spools at the same time
- Presets cover PA nylon, TPU, and seven other listed filament types
- Temperature range reaches 70°C
- Sealed feed-through design supports drying and printing from the box
Cons:- Two-spool capacity falls short of the SUNLU S4 for batch work
- 150 W heater has lower stated power than the S4’s 350 W system
Best for: Two-printer households or makers who want preset drying for nylon and TPU with filament feed-through.
Not ideal for: Print farms or users drying three or more spools simultaneously; this unit holds two.
- Capacity:2 spools, 1 kg each
- Temperature range:40–70°C
- Heater:150 W PTC
- Filament presets:9 types, including PA and TPU
- Maximum drying time:98 hours
- Feed-through holes:2

Our verdict“Pick the SH02 for preset, two-spool drying with feed-through; choose the SUNLU S4 when capacity is the priority.”
Polymaker Polydryer Filament Storage Box for 1kg PA Nylon PLA PETG ASA ABS
This Polymaker PolyDryer storage box takes a different approach from the heated Comgrow SH02: it is designed to keep a spool protected between jobs, not actively dry it. Its sealed enclosure, desiccant support, and built-in hygrometer help users track storage conditions, while feed-through lets filament remain enclosed during printing. That makes it a practical companion for nylon or TPU that is already dry and needs protection from humid air. The limitation is decisive for this roundup: the supplied product description does not list a heater or drying temperature, so it cannot replace an active dryer for wet filament. Compared with the Polymaker Dryer Dock and Storage Box, this is the storage-box-only option; choose the dock version if you need heating as well.
Pros:- Sealed design with desiccant support helps limit moisture exposure
- Built-in hygrometer makes storage conditions visible
- Feed-through allows printing without opening the enclosure
- Supports listed filament diameters from 1.75 mm to 3.00 mm
Cons:- No active heater or drying temperature is listed
- Limited to one spool up to 1 kg
- Less suitable than the Polymaker Dryer Dock when active drying is required
Best for: Nylon and TPU users who need sealed, monitored storage for a 1 kg spool that is already dry.
Not ideal for: Anyone seeking active moisture removal or a heater for wet filament; no heating specs are provided.
- Capacity:1 spool, up to 1 kg
- Storage method:Sealed enclosure with desiccant support
- Humidity monitoring:Built-in hygrometer
- Filament types:PA/Nylon, TPU, PLA, PETG, ABS, ASA, PVB
- Filament diameters:1.75 mm, 2.85 mm, 3.00 mm
- Feed-through:Designed for printing while filament remains enclosed
- Item weight:0.7 kg
Our verdict“Choose this box to store already-dry nylon or TPU with less exposure to room humidity, not to dry wet filament.”
Creality Space PI Filament Dryer – 3D Printer Filament Dehydrator with 360° Heating
For a single spool of nylon or TPU, the Creality Space PI offers active heating without the footprint of the four-spool SUNLU S4. Its 360° hot-air circulation, adjustable 45–70°C range, and timer up to 48 hours give users control over a drying cycle rather than relying on storage alone. The touch screen and power-outage memory add convenience for longer runs. The compromise is capacity: unlike the Comgrow SH02, which accommodates two spools, this model is presented as a single-spool dryer, so it is less useful for parallel jobs. It is also specified for 110V input, a limitation for buyers outside compatible power regions. I’d favor it for one-spool drying with adjustable settings, but not for batch work or sealed storage after drying.
Pros:- 360° hot-air circulation is designed for even heating
- Temperature settings span 45–70°C
- Timer supports drying cycles up to 48 hours
- Memory function can retain settings after a power outage
Cons:- Single-spool format is less suited to batch drying than the Comgrow SH02
- 110V input limits compatibility with other power systems
- Does not provide the sealed storage features of the Polymaker PolyDryer box
Best for: Makers who dry one spool of nylon or TPU at a time and want adjustable temperature and cycle length.
Not ideal for: Users who need multi-spool drying, sealed long-term storage, or a power supply other than 110V.
- Power:110 W
- Input:110 V, 50/60 Hz
- Temperature range:45–70°C
- Timer:0–48 hours
- Filament diameters:1.75 mm, 2.85 mm
- Supported materials:Nylon, ABS, PETG, PLA, TPU, high-performance composites
- Weight:1.5 kg
Our verdict“Choose the Space PI for adjustable, single-spool nylon or TPU drying if 110V power suits your setup.”
Polymaker Filament Dryer & Storage Box for 1kg Filament
The Polymaker Dryer Dock and Storage Box is the more complete Polymaker choice for nylon and TPU: unlike the PolyDryer storage box alone, this version combines a dryer dock with sealed storage and a hygrometer. That pairing suits users who want one setup for active conditioning, monitoring, and feeding filament to a printer. The listed compatibility includes PA nylon and TPU across three common filament diameters. Its 1 kg spool capacity keeps the system focused on individual jobs, though; the SUNLU S4 is a better fit for drying several spools together, and the Comgrow SH02 provides a stated two-spool capacity. The product data does not specify a temperature range or heater power, which makes it harder to compare drying performance for moisture-sensitive nylon. I’d choose it for an integrated one-spool workflow, not maximum throughput.
Pros:- Combines a dryer dock with sealed storage
- Built-in hygrometer provides a visible humidity reading
- Supports PA nylon and TPU as well as other common materials
- Accepts 1.75 mm, 2.85 mm, and 3.00 mm filament
Cons:- Designed around a single 1 kg spool rather than batch drying
- Product data does not specify heater power or temperature range
- Requires electricity for its heating and monitoring functions
Best for: Makers who want one-spool active drying, humidity monitoring, sealed storage, and printer feed-through in one setup.
Not ideal for: Buyers who need documented temperature settings or simultaneous drying for multiple spools.
- Capacity:1 kg filament
- Filament diameters:1.75 mm, 2.85 mm, 3.00 mm
- Supported materials:PA Nylon, PLA, PVB, PETG, ABS, ASA, TPU
- Humidity monitoring:Built-in hygrometer
- Storage:Sealed storage box
- Item weight:1.3 kg
- Material:Plastic
Our verdict“Choose the Polymaker Dryer Dock if you want integrated one-spool drying and protected storage, and can work with the unspecified heating details.”
How We Picked
I compared the 15 listed products against the needs of nylon and TPU printing, not just general filament storage. The main criteria were stated material compatibility, temperature information, heating and airflow details, spool capacity, ease of feeding filament while drying, and whether the design also offers sealed storage. A feature only counted when the product listing named it; I did not treat a broad claim like “filament dryer” as proof of suitable nylon settings.
The ranking favors options whose listed features speak clearly to flexible and moisture-sensitive materials, then weighs capacity and day-to-day usefulness. That puts the SUNLU S4 models and the Creality Space Pi SE Pro 2.0 ahead of simpler single-spool choices for versatility, while storage-focused Polymaker models serve a different need. Similar names do not guarantee identical specifications, so I distinguish versions and avoid assuming that a feature on one model applies to another. Buyers should confirm the unit’s actual temperature range against the filament maker’s drying guidance before use.
Factors to Consider When Choosing Filament Dryer For Nylon And Tpu
Choosing a dryer for nylon and TPU is less about collecting the most features and more about matching heat, capacity, and storage to your routine. These factors can help you avoid a common mismatch: buying a box that holds a spool but cannot run at the conditions your filament requires.
Match the Temperature Range to the Filament
Start with the drying instructions from the filament manufacturer, then compare them with the dryer’s stated temperature range. Nylon and TPU are not interchangeable with PLA: a setting suitable for one material may be unsuitable for another, and different formulations can have different requirements. Do not infer a dryer’s maximum temperature from its product family or another version with a similar name. A dryer with a higher listed maximum can offer more flexibility, but only if its controls let you select the needed setting. If a listing omits temperature details, treat that as an information gap and verify the exact model before buying.
Choose Capacity Around Your Actual Workflow
Count the spools you need to dry at once, not just the number of printers on your desk. A single-spool unit can be a sensible fit for occasional nylon or TPU jobs, while a multi-spool design helps when several materials are in rotation. Extra capacity may take more space and can be unnecessary if you usually dry one spool at a time. Also check whether the dryer can feed filament directly to the printer while the spool turns freely. A spool that fits inside the chamber but cannot feed smoothly may create more friction or handling than expected.
Look for Useful Heat Distribution Details
Drying performance depends on more than the heater’s stated maximum: air movement and how heat reaches the spool also matter. A listing that names fan circulation or 360-degree hot air offers more information than one that only says it has a heater. Still, airflow claims do not replace checking the temperature range or following filament-specific guidance. Avoid assuming that a faster heating claim means a spool will be fully dry sooner; spool size, material, starting moisture, and drying time all affect the result. When details are sparse, favor clear controls and instructions over impressive-sounding labels.
Decide Whether You Need Drying, Storage, or Both
A dryer actively applies heat, while a storage box primarily limits exposure to ambient humidity; some products are designed to cover both tasks. For nylon and TPU, drying a spool before printing may not protect it once it sits out beside the printer. If you print those materials often, consider how the unit seals after the heating cycle and whether filament can stay inside while feeding. A storage-focused box can be useful between jobs, but do not assume it can replace a controlled drying cycle. Buyers who print intermittently may get more value from a combined approach than from extra heating features alone.
Check Spool Fit, Feed Path, and Material Compatibility
Spool width, diameter, and material can affect whether a roll turns freely in a dryer. Check the maker’s supported spool dimensions, especially if you use large, cardboard, or nonstandard spools. Confirm the filament diameter and feed outlet suit your printer setup; compatibility with 1.75 mm filament does not automatically mean every spool fits. For TPU, a smooth, low-resistance path matters because flexible filament can be less forgiving of snags than rigid filament. A little time spent checking fit can prevent buying a dryer that technically holds a spool but proves awkward to print from.
Pay for Features That Solve a Real Bottleneck
Extra capacity, circulation fans, and touch controls are worthwhile when they address a repeated problem in your setup. A multi-spool unit makes more sense for several active materials; a simpler dryer can be the better choice when you only need to condition one spool occasionally. Do not pay for a feature based on a similar model’s description: compare the exact version, including color or generation, because listings can differ. If your main concern is keeping filament dry between prints, prioritize sealing and storage details over a higher heat setting you rarely need. When nylon is a regular material, favor explicit temperature and material information over a low-detail listing.
Frequently Asked Questions
Can one dryer handle both nylon and TPU?
It can, provided its temperature range and controls match the drying guidance for both specific filaments. Nylon and TPU do not necessarily use the same drying settings, so a single preset may not suit every spool. Check the filament maker’s instructions and verify that the exact dryer version allows the needed temperature and time settings. In this roundup, the SUNLU S4 listings explicitly name both materials, while compatibility details vary across other products. Do not treat a general dryer label as confirmation that a particular nylon or TPU is supported.
Is a multi-spool dryer worth choosing if I only print one spool at a time?
Usually, a multi-spool design pays off when you need to dry several spools together or keep multiple materials ready. If you print one spool at a time and have limited desk space, a single-spool model may be easier to place and operate. Capacity alone does not tell you whether the dryer can independently control each spool or suit every material at once. Check how you would use it, including whether you can print directly from the unit. The SUNLU S4 is the clearest multi-spool option in this group, but its extra capacity may be more than a casual user needs.
Can I print directly from a filament dryer?
Many dryer designs include a filament outlet, but you should confirm that the exact model supports feeding while the spool rotates. The outlet’s position, spool clearance, and resistance along the filament path can matter as much as the presence of a port. This is especially relevant for TPU, where snags or excessive drag can interfere with feeding. Check whether your printer’s location lets the filament travel cleanly from dryer to extruder without sharp bends. If the listing does not explain direct feeding, verify the manual before making it a deciding feature.
Will a dry box keep nylon or TPU dry after the heating cycle?
A sealed box can reduce exposure to humid air, but that is different from actively removing moisture with heat. How well it protects a spool depends on the seal, how often the lid is opened, and the conditions around the printer. Some products combine drying and storage, while others emphasize one role more than the other. Look for clear information about sealing and whether the filament can remain inside during printing. If you print nylon or TPU over several days, plan for both a drying routine and sensible storage between sessions.
What should I do when two listings have nearly the same product name?
Compare the complete model name and its listed specifications rather than assuming the versions are identical. This roundup includes repeated SUNLU S2 and S4 names, plus multiple Creality Space Pi dryers and Comgrow SH01 variants. Check the maximum temperature, named material compatibility, spool capacity, airflow features, and included controls on the exact listing you intend to buy. Color or “upgrade” wording alone does not establish which features changed. If a key detail is missing, consult the product manual or manufacturer before relying on that dryer for nylon settings.
Conclusion
For the broadest match to nylon and TPU plus multi-spool flexibility, I’d choose the SUNLU S4 as the best overall option, checking the exact version’s controls before ordering. The Creality Space Pi SE Pro 2.0 is my pick for buyers who prioritize stated 360° circulating heat in a one-kilogram-spool format, while the Polymaker PolyDryer suits those who value filament storage alongside drying. For a simpler starting point, a single-spool Creality Space Pi or SUNLU S2 may be easier to fit into a basic setup, but verify nylon and TPU compatibility rather than assuming it. The best value depends on which features you will use: choose a straightforward single-spool dryer for occasional jobs, and pay for multi-spool capacity or added circulation only when it solves a real workflow need. For specialty materials, let the filament maker’s drying guidance and the dryer’s documented temperature range decide the final choice.
