Since I’ve found very little information on printing PolyCarbonate, I’ll start a thread and see where it goes.
http://reprap.org/wiki/Polycarbonate doesn’t help a whole lot, but it’s somewhere to start.
I’m using a Hexagon hotend with Taz 4.
PC is very stringy, leaving tiny threads all over the place. Tried printing at a low temp, 260F and up to 290F, doensn’t seem to change stringiness. This is pretty annoying.
PC does not stick to anything it seems. PET, Painters Tape, ABS juice, Kapton tape, all don’t work for PC. 3M double sided tape works a little bit, but PC stick to the tape and ends up pulling the tape off the table. Tried bed temps of 60F up to 95F. Cooler temps are worse for sticking to the bed. I will be ordering some garolite and PEI to try those.
During one print I noticed when the extruder would retract the filament, it would lift that section off the bed at the same time. I’m going to play with retract settings to see if this can be fixed.
Had a little delamination when I left my enclosure open. Not as bad as ABS.
