Based on recommendations from other sites (whatever that may be worth in the AI spam age) the Creality Space Pi is supposed to be good and is available here in Germany. Any experience with that? Is there anything significantly better (e.g. smaller temperature gradient across the spool)?
DIY solution would be fine too as long as it doesn't require printing parts.
Single spool is likely to be good enough; must be able to dry / keep dry while printing. Suitable for at least PLA and PETG.
2/3
@blue_led I have used a modded food dehydrator and a PolyMaker PolyDryer, and I much prefer the PolyDryer. Better temperature regulation and end result, even if it does take longer than the dehydrator. I have ruined multiple spools of filament in the dehydrator because they got too hot for various reasons, even when it was set at/below what should have been the proper drying temp.
Also with the PolyDryer you don't need to prop it open to vent moisture like many others do
@blue_led I have one dryer+box and two add-on boxes and they all came with orange -> blue indicating desiccant.
Power level isn't exact but it's close enough to a temp range. I'm not sure if there is any compelling reason to dial it in more accurately, there is a guide with power levels for different filaments that get in the right ranges.
There are also printable rigs to dry multiple spools but I haven't tried any of them.
Attached: 4 images Got a PolyDryer now. Being who am am, of course I placed a bunch of temperature sensors in it and did a test run first (plus I wanted to know what temperatures the "power levels" mapped to). The results surprise me; I would have expected the hot air to circulate around the spool; instead it seems to take an intentional(?) shortcut at the bottom. Anyone know why it's designed this way? 1/3 #3DPrinting #FilamentDrying #PolyDryer
