I have some very consistent issues with warping when printing ASA/ABS, which is really annoying since I’m trying to print my voron parts. It’s not warping massively, but enough to mess things up.
I print with these general settings, on a textured PEI flex-plate.
- heated chamber @ 45-47C (can’t go much higher)
- bed temp @105C
- first layer 255C, other layers 245C
- fan off, unless it’s an overhang >=50% or layer time is <10s. Fan maxes out @70% unless bridging.
- speed 200/120 mm/s inner/outer walls
- first layer 50mm/s, 80mm/s infill
I’ve tried both with my regular Z-offset which creates a good uniform first layer, and slightly lower to kind of push it more on to the plate (but worse looking)
- I’ve cleaned the plate with pure IPA
- I’ve tried glue stick
- I’ve tried brim both skirts/mouse ears, which help but don’t eliminate it. (5mm, 0.15mm space)
ABS seems to be a little easier to print than the ASA. I’m using filament from Polymaker
May not help at all, but one thing I noticed with my prints was that if I removed it before the bed cooled, it would often warp. I’ve since left it until it cools to room temperature and have got much better results.
Does it warp and lift from the base plate during the print, or does it stay stuck down? The former could be because of lack of adhesive and a raft/brim/glue may help, but the latter may just be lifting it off too early.
It warps during printing, raft/brim and glue doesn’t fix it.
