So tried out some PETG for the first time, and the first couple prints went really well. but I believe it’s picked up quite a bit of moisture, sitting in the basement.

What’s the current recommendation for a filament dryer? there was one on /r/3dprintingdeals a bit back, a Sunlu S2. is the S1 good enough, or should someone who’s fairly recreational with everything spring for a S2? I see food dehydrators recommended sometimes, is there anything specific to look for in one?

    With all the rain we’ve been getting the past month I’ll probably need a dryer too… I heard an oven works pretty well in a pinch.

      The number of photos I’ve seen of completely melted filament rolls, due to either poor oven thermostats or inattentive users … I cannot endorse this technique.

      If you’re on a budget, probably better to just power up your heated bed, with a box over top, and dry your spool inside there.

      Repurposed food dehydrators seem to rate highly, if you can find a used one for cheap.

      I ended up biting the $40 bullet and grabbing a Filadryer S2 when it was on sale.

    I have Sunlu S1 dryer. I added fan and changed thermistor position. I tried it with PLA, PETG, ASA with good experience. S2 have two heater plates, touch display. But for me, it have filament out way in bad position.

    I have a couple S1s that I like. They don’t have a built in fan or hygrometer like the new ones, but they seem to work. You can print mounts for cheap hygrometers if you want (not necessary but interesting to see the humidity change with the dryer running). I usually run the dryer with whichever spool I’m using when printing and it seems to keep the filament in good condition.

    Thats pretty cool. I wish I knew this before I bought my Sunlu. I used to use my toaster oven that had a food dehydrator function, but my so got tried of me using it for hours. I had to get a dedicated dryer.

    A food dehydrator or the purpose built Sunlu would work great for this purpose, but in my opinion there are easier procedural ways that don’t require additional appliances.

    I just keep my spools in a large sealing storage tub with an oven safe tray of loose silica desiccant beads at the bottom. Every few weeks the tray of desiccant gets put through a heat cycle in the oven (about 150-75 for 10-15 minutes) and goes right back in the bin. You really only have to fight the moisture that gets absorbed by the spool while on the printer before going back in the tub, and the moisture within the air exchange every time the tub is opened.

    Keeps my spools nice and dry without much fuss.

      I do something similar. I keep mine in large zip lock bags I got from Ikea with the desiccant packs that came with the spool. These spools then all go in a large Rubbermaid container (which holds 13 1kg spools) so they’re doubly sealed and all packed neatly in one place.
