Questions about PC-ABS
What temperature should I print PC-ABS at?
Nozzle 250–280 °C and bed 95–110 °C are the usual range. Start in the middle and tune with a temperature tower; an enclosure helps with larger parts.
How many metres of PC-ABS are in a 1 kg spool?
About 378 m at 1.75 mm (density 1.1 g/cm³). One metre weighs 2.65 g.
Does PC-ABS need drying?
Yes — it is moderately hygroscopic. Dry at 80 °C for 8 hours before printing if it has been open for more than a few days.
How much does PC-ABS shrink?
About 0.7% linear. To compensate, scale X and Y by 100.70% in the slicer, or measure a test print and use the shrinkage calculator.
