Review: Good value, lightweight and effective - Very compact filament dryer. So far I have used it for ePLA and TPU spools while printing. Nice and lightweight so it sits on the top of the printer currently on a small custom printed plate (though it will be moved to a shelf soon). Recommended for those printers that do not have an AMS type changer system and want a good way to keep their filaments in good condition while they are printing.
Review: Good value, dries fine and helps stop spool issues. - For the price I am very pleased with this purchase. The filament does get exposed to air on its way to the printer so I just bought some ptfe tubing, a pc4-m10 fitting and printed out a fitting for the drier which someone had already uploaded to the web. I put it altogether and it works great. But I think it would work without this but hey, for a few quid I thought it was worth it. As the spool fits on the two rollers it helps to stop the filament rolling over the side and getting stuck which has happened before I got the drier and messed up prints for me. So that fixes another problem for me. Since getting the drier, and used it according to the filament manufacturers instructions, i have had no problems with stringing or bubbling. I used it for petg and pla. It doesn't go to as high a temperature as others so check what are the temperatures you need for the filaments that you use. But for me this completely works for the filaments that i use. I should note that I do keep my filament in air tight bags with most of the air removed. I don't know if this drier would work if you keep your spools in the open. But for me it's been an excellent purchase that I am very happy with.

## Questions & Answers

**Q: Does this come with an UK plug ?**
A: Yes it does.

**Q: Will this dry a badly moisture absorbed Tpu roll ?**
A: The box may in time dry out the material, but it will only stay on for I think 5 hrs. Your best bet would be to put it into a oven at about 6o to 70C for 8 hrs. Then you could use the box to keep it dry when you are printing that works for me.

**Q: How do you work out humidity?**
A: With pla it will be brittle and snap easily if it’s dry it will just bend

**Q: Can anyone tell me the maximum width of a spool that this can hold? Or if a Prusament spool will fit inside?**
A: The max size is the width of a 1kg spool, atleast thests the biggest I've put into it and that's quite snug

### ⭐⭐⭐⭐ A very simple device with some weaknesses, but good enough for the price.
*by A***E on 5 September 2025*

It's a very simple device that generally does what it's supposed to. You put the filament inside, turn it on, it heats up. A small fan circulates the air for more even heating. The manual is very sparse and doesn't really match what the buttons are actually doing. The QR code link to the full manual is broken. With a little experimentation I figured out how to use it (you have to hold the buttons to enter settings), but needless to say a manual that actually matches the product would be nice. One fundamental problem with how the device works is that there is no way for moist air to escape. You have to open and close it every 1-2 hours during operation to exchange the air. Otherwise you will just have hot moist air inside. I was still able to dry my PLA filament and achieved a noticeable decrease in stringing, so it does work. I'm only deducting 1 star for the downsides because the device is very cheap after all.
