It will be a 240x280x70ish speaker stand. The first go ground with it flat and support free resulted in warping despite a 60°C chamber, so I stood it on its end, cut print speed by a third, and added the breaks to reduce stress.
This will take a while…
Note that the bottom has a chmafer, so although there’s a shadow it’s not warping.
Looks good so far. Make sure to vent/not breath too many ASA fumes.
Vent and filter! I have one of these under the bed and the printer is vented.
But it stinks so good!
I’ve had good results with reversing print-direction on odd layers but for all layers, not just for overhangs.
That’s an interesting suggestion. What failure mode have you found that to help with? I am under the impression that the temperature gradiant between the bottom of the print and the top of the print, combined with thermal expansion, is the reason why printed parts warp. ABS/ASA expand/contract twice as much as PLA.
It seems to help reduce warping in general for ASA in my experience. I haven’t done a deeper investigation to collect actual data, but anecdotally I seem to have way less issues with large ASA prints warping since I started using it.

Tip: large prints can lift your mag sheet when they warp, some clips like we used in the old days would help. This one doesn’t look big enough for that tho.
Make sure the fan is off, recent abs and asa presets in slicers have it enabled. The fan-speed view in the slicer can help.
