I only skimmed for now and will keep a lookout for the mentioned post about the Creality.

But all filament dryers I've seen so far seems to be pure garbage I'd never trust in my home. Which kind of makes sense, they are easy and cheap to make so only bottom of the barrel crap can compete.

But if anyone knows better or have recommendations about proper units / brands please let me know.

Hey, I'm the author of the blog article. I saw your comment and decided to write a detailed critical review of the dryer and write about the specifications. you can find it here: https://syntaxglow.com/2025/02/08/creality-space-pi-filament... or just look at my blog for the latest article :) I'm curious of what you think.

Thanks! And good job, it is quite thorough. I have not done my research and I feel that I completely lack intuition for this. (How much ventilation is needed and how come many of these dryers don't / barely let the humid air out? And inversely how good/bad is for storage considering the ventilation. How good are desiccant bags anyway etc.)

But it looks good, best I've seen.

Would be nice with an electrical teardown just get a feel for the safety (I have no clue about the creality brand).

I like the one from Polymaker, though that is mostly because it's modular which I needed for a hard to reach space. It claims to have a thermal fuse. https://polymaker.com/introducing-polydryer

The plastic feels solid, but I did not take it apart to check if it has decent crimping or electronics.

If you trust your 3d printer, you could do what the article suggested and use your heatbed.

I have a Sunlu S4, and it works well.

Thanks, the S4 looks really nice. But it seems like they shafted their kickstarter supporters. Risk is of course part of the deal but Sunlu is an established brand and is actively selling the same device they don't deliver to the people that helped to fund it...

Also, Sunlu (S2) didn't seem to impress that much so overall, not too eager to support / try them out.
