ASA warping CORE one and satin poweder sheet
Ok,
I bought an CORE one everything i print is very clean without issues.
Last night i tried asa on satin powder coated sheet.
I had chamber fans on 2% because i have my house ventilation above the rear exhaust to reduce smells
I printed a model that is not really big but it warped like crazy. The print head was rubbing the infill till the point the nozzle got clogged and it did not turned out nice.
I intelntionally bought the satin powder sheet for this instance.
0.2 structural
90% infill
No glue
Chamber fans 2-3%
No brims or support
Esun ASA+ on prusament ASA profile.
What am i doing wrong?
I must not use the smooth pei sheet right?
Add glue or no glue?
Add very much brims?
Google and everything is ver contradicting about glues and sheets
Thank in advance

P.s. i had this same problem on a large ~230mm Pursament PETG tray for the side. It also warped 1-2mm on both sides. On the textured satin sheet
RE: ASA warping CORE one and satin poweder sheet
I solved it.
Added a 15-20mm brim
Turned print fan down to 10%
And slowed max speed to 80mm/sec
RE:
Looking at some of your settings, I think that 90% infill is in the vast majority of occasions a waste of time and filament. Besides, it increases a lot the chances of warping, If you want a strong print, add more vertical/horizontal perimeters,
Medium-large size models printed in ASA with sharp corners are an ideal candidate for warping. You want all the help possible to fight this problem. No need to recommend the use of an enclosure, with a CoreOne that’s already solved.
What I’d do next :
1- Reduce infill to 40% maximum. I think as well that 4 top /bottom layers and 4 perimeters would be enough to get a strong part.
2- Use a large brim with 0 mm gap. Set elephant foot compensation to a minimum or to zero.
3- Use adhesive, but not that messy glue stick. Hairspray based products ( 3Dlac, Laverneer .. ) are cleaner and easier to apply. Dedicated adhesives like Dimafix or Magigoo are also good but more expensive. Of course, the plate must sprayed beforehand out of the printer.
4- A satin plate is usually a good choice for almost all types of filaments but when warping is likely to be a big problem, it’s preferable the better adhesion provided by a smooth plate. Don’t forget that ASA and other filaments absolutely need an intermediate layer of adhesive when printing on this plate. Otherwise you risk damaging the PEI sheet
5- the higher the temperature inside the enclosure, the better. When the print is done, let it cool down slowly before removing it. Don't open the doors of the enclosure.
