Frequently Asked Questions

verified +347 experts reviewed it as the best choice in 2026
Q1 Is 50°C (122°F) hot enough for my filament?
Adjustable from 45 to 50°C (113 to 122°F), a range suited to everyday PLA and PETG. Check the temperature guidance printed on your spool to match it to your filament.
Q2 Can I print straight from the dryer while it runs?
Yes. Filament can feed to your printer through a PTFE tube from a fitting on the lid while the spool stays inside, so there is no unloading. Four PTFE tubes and six plugs come in the box.
Q3 Will my 1 kg (2.2 lb) spools fit?
Standard 1 kg (2.2 lb) spools fit, two at a time. Each spool can be up to 200 mm (7.9 in) across and 73 mm (2.9 in) wide, so measure your spool's diameter and width to check.
Q4 Do I need to add desiccant?
The built-in desiccant box holds your own desiccant for extra moisture control between runs. The heating plate and fan do the main drying.
Q5 Will it keep my spools dry when it's switched off?
The sealed structure, with a silicone seal strip and insulation cotton, is built so filament stays protected from moisture even when powered off. Keep the lid closed and the plugs in the fittings.
Q6 What comes in the box?
One K-02 dual-spool filament dryer, one user manual, one power adapter with a US plug, four PTFE tubes, one rotating shaft and six plugs.
