Printing ABS in a cold acrylic 1/4" sheet seems to be good to prevent warping. Bigger problem become removing the print without breaking the acrylic because it sticks too well. Any suggestions to easy removal after printing on acrylic?
Wait wait…you printed right on a piece of acrylic? It may have bonded with it. Isn’t acrylic not far away (chemically) from ABS…at least to be subject to fusing at these temperatures? Did you consider 2 options: scaffold that can be discarded and broken off for each print, or, dabbing the base of the print with acetone to loosen it off?
@Samer_Najia , acetone will cause acrylic to “craze” and fracture. I’m afraid @Greg_Nutt may be very well screwed in this situation.
I have successfully printed and removed a number of times from the acrylic sheet. ABS sticks beautifully and doesn’t warp. BUT, the proximity seems to be the key on the first layer. Too close and it bonds too hard and becomes very difficult to remove. To far and it starts to separate. I broke my acrylic on the last attempt but the part did separate.
There must be a way to take advantage of this cold ABS option on acrylic.
I’m also wondering if extruding the first abs layer at the coolest possible will create a weak enough bond on the acrylic so it sticks enough for printing but breaks off easily enough. I think that may have worked for me already as my first prints started at 200C, but the last print, which broke the acrylic, was at 240C.
I would love to hear your results and I think I can replicate them. What thickness acrylic?
I was using 1/4" thick (6mm).
