Best Filament Dryer for Nylon (2026): 5 Picks for Damp Spools

What to look for in the best filament dryer for nylon

Nylon is named in every listing here, but the boxes differ in how hot they run and how many spools they hold. The Comgrow SH03 reaches 85 degrees, the Creality Space Pi V2 names 75 degrees in its title, and the SUNLU S4 and SUNLU S2 Plus both reach 70 degrees, while the Creality Space Pi SE reaches 65 degrees. A higher maximum gives more room for damp spools, and the two 4-spool boxes suit a bench that runs several materials at once.

Print-while-drying matters as much as temperature. The Creality Space Pi SE has two rollers in the box so printing can continue while drying, and the SUNLU S2 Plus is described as a spool holder that dries during printing. The SUNLU S4 has eight filament outlets for several printers, and the Comgrow SH03 gives each chamber its own filament output tube. Fans also matter: the Creality boxes circulate hot air through 360 degrees, the SUNLU S4 uses three circulation fans, and the Comgrow SH03 uses a 360 degree hot air circulation fan.

Match the temperature range to the spool

Each box states a temperature range, and the ranges here run from 45 degrees to 85 degrees at the top end. The Comgrow SH03 adjusts from 45 degrees to 85 degrees, the Creality Space Pi V2 sets from 45 degrees to 70 degrees in its bullets while its title names 75 degrees, and the SUNLU S4 and SUNLU S2 Plus both set from 35 degrees to 70 degrees. The Creality Space Pi SE sets from 45 degrees to 65 degrees and reaches 65 degrees within 15 minutes. Compare the stated range with the material list for each box, and note that every box here names PA or nylon among its materials.

Capacity: one spool or four

Single-spool boxes fit one spool at a time and suit a maker who prints one material in a session. The SUNLU S4 dries up to four 1KG filaments at once, and the Comgrow SH03 holds up to four 1KG spools in two chambers of two rolls each. A 4-spool box takes more bench space: the SUNLU S4 measures 460 by 220 by 310 mm outside, while the Creality Space Pi SE measures 266 by 237 by 99 mm. Check the stated spool diameters too, since the SUNLU boxes accept 1.75mm, 2.85mm and 3.00mm filament, while the Creality and Comgrow boxes list 1.75mm and 2.85mm.

Controls and monitoring

Timers and displays decide how much attention drying needs. The SUNLU S4 and SUNLU S2 Plus set timers from 0 to 99 hours, the Creality Space Pi V2 sets from 0 to 48 hours, and the Creality Space Pi SE sets from 0 to 24 hours. The Comgrow SH03 runs for a maximum continuous operation time of 98 hours and adds an automatic drying mode that starts when internal humidity passes a preset threshold and stops after a 30-minute countdown. Touch screens appear on the SUNLU S2 Plus, the Creality Space Pi V2 with a 3.7-inch touch screen, and the Comgrow SH03, while the Creality Space Pi V2 also remembers its previous material and temperature settings after a power failure.

Project Match

• Nylon parts printed from a damp spool: any of the five picks, since each listing names PA or nylon.
• Several materials drying at once: the SUNLU S4 or the Comgrow SH03, both 4-spool boxes.
• Printing while a spool dries: the Creality Space Pi SE, with two rollers in the box, or the SUNLU S2 Plus, described as drying during printing.
• High-temperature drying: the Comgrow SH03 at 85 degrees, or the Creality Space Pi V2, whose title names 75 degrees.
• A small bench with one spool in use: the Creality Space Pi SE or the SUNLU S2 Plus, both single-spool boxes.

How the scores add up

Each dryer is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. A spec the listing does not publish scores nothing.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

FAQ: lasers and CNC

Do you need a filament dryer for nylon?

A dryer removes moisture that damp filament picks up from the air, and the listings here describe damp filament causing stringing, clogging and poor adhesion. Every box in this guide names nylon among its materials, so a dryer is a practical addition when spools sit open or prints show moisture problems.

How do you use a filament dryer?

Place the spool in the box, set the temperature and time for the material, and close the lid. The Creality Space Pi SE can print while drying through its two rollers, the SUNLU S2 Plus works as a spool holder during printing, and the SUNLU S4 feeds several printers through eight filament outlets.

How long do you dry filament in a dryer?

The boxes here give different timer ranges rather than one fixed drying time: the Creality Space Pi SE sets from 0 to 24 hours, the Creality Space Pi V2 sets from 0 to 48 hours, the SUNLU S4 and SUNLU S2 Plus set from 0 to 99 hours, and the Comgrow SH03 runs for a maximum continuous operation time of 98 hours. Set the timer for the spool in hand and check the result before printing.

Do I need a filament dryer if I print only occasionally?

Occasional printing leaves spools open longer between jobs, which is when moisture builds up. The SUNLU S2 Plus is described as reviving damp filament, and the Comgrow SH03 has an automatic drying mode that starts when internal humidity passes a preset threshold, so a box earns its place even between print sessions.
