Comment on I like big beds and I cannot lie, pt 2. Any hints to improve ASA adhesion?

I am having the same problems as you with ASA (and ABS also). If the footprint is large I get warping. If the footprint is small, I get warping and also the friction from the nozzle rubbing on the top layers pushes the part loose from the sheet. So if you do try that, keep an eye on it!

I’ve tried Magigoo and that helped a bit. I ordered a Fabreeko “Honey Badger” sheet that some people online were raving about as solving all their problems. But I’m expecting I won’t actually solve the problem unless I have a somewhat heated enclosure.

I’m hoping to see something else to try in this thread, though!

I don’t have any problems with small parts. For example, I reprinted my Stealthburner with zero issues. I’ve done some larger parts as well, but I designed those to be easier print with large radius corners.

I’ve mulled over the same PEI sheet, lol. Did you get smooth or textured? I have better adhesion on the smooth side of my current sheet.

  I did some Stealthburner parts in ABS and everything came out okay but the one with the overhang never printed quite right for me, so it looks sloppy. I think the difference is that it had too much surface area, cooled, and warped. That’s what I’d be afraid of printing a box upside down, the heatbed has to compete against more air.
  
  We must have found the same comment sections :) I’m going for a smooth one myself, I also saw better results on my current smooth sheet.

    I didn’t have any issues with any of the stealthburner overhangs. There is the one bridge on stealthburner_printhead_rapido_rear_cw2 that’s not perfect, but it’s certainly good enough. Some pictures are here.

    I ran into people on the Voron forums vouching for it. It sounds like there was a double sided honey badger offering at one point, but that’s no longer the case :( I wonder if buildtak would mind facing the bed from time to time…
