I managed to print a few PC parts, however I did not get a single good part.
- 0.6mm nozzle, line width 0.6mm, no bottom support, 25mm/s print speed, 250 deg extruder temp, 80 deg heated bed temp
(The nozzle to bed z-home distance was set to 0.4mm.)
1) The extruded filament would ball up around the nozzle, to the point where the part could break away from the heated bed. [Perhaps the nozzle was too close to part.]
2) The layers did not adhere well together, to the point that they would delaminate when bending the clip.
