Prusament ASA sticking too well on PEI sheet
I have a textured sheet that has pulled some of the surface off. It tends to stick too much now. It is about 3 years old. I have saved it for certain hard to stick filaments.
I filled the defective areas on the PEI shett with 2 component epoxy glue and sanded the repaired areas clean flat.
I have made a short manual here (only in German language):
ohhh, the new satin sheet is in stock. Maybe this is the solution. I ordered it at least.
For me the list was new, maybe there are more who will find it helpful.
I was able to use this solution:
PETG as the first layer, peeling went well and surface is very flat and without warping.
Nice guide, thanks!
Back then when i’ve had delta printer i used abs-acetone solution which i put on kapton as preparation. I never had to use any kind of glue.
Finally, I printed ASA again.
Just quickly my findings:
- Brand: Fillamentum ASA
- Printer Mk3S in an enclosure, temperature goes up to ~40°C
- Sheet: Textured steel sheet from prusa
1) flat object, ca 15cm x 10cm
-> failed due to warping (corners came off)
2) smaller piece ca 10 cm x 3 cm
! Added 5mm brim to avoid the corners lifting off
-> worked well
3) two pieces 12 cm x 5 cm, 9 cm x 8 cm, again with 5mm brim
-> worked well, too!
For print 1+2 I struggled a bit to get it off afterwards.
In the third attempt, I took the build plate out immediately when the print was done. As soon as I heard the crackling sound (part coming off from build plate?) I flexed the plate a little and the print really popped off easily.
Summary: ASA + Textured Sheet + Brim works well so far. Cool down before taking the print off.
Good to know. I am going to have to try a brim on ABS-T.
With ASA, I have not needed one. I switched plates and ASA sticks well again.
I think I should add two more pieces of information:
- I am not very experienced in printing ASA. (Printed 7 parts so far, one failed due to warping)
So maybe, the things that I changed did not cause the success after all. I did not do testing brim vs no brim under otherwise identical conditions. Maybe doing a rain dance would have yielded the same results after all 😉 And never forget about Dunning Kruger 😉
- The part that lifted off had a very narrow contact area on the printbed, and on top of that, chamfered edges. I guess that makes warping more likely.
However, I thought and still think is is valuable to know a combination of settings, conditions,... which gives good printing results.
Also: I am printing a huge ASA part right now. It is 262mm long and mostly only 9mm wide. So far (75% done) the print is going flawlessly. I will post a picture once it is finished.
