Printing tips
- Enclosure is close to mandatory above palm-sized parts; drafts cause cracking.
- Turn the part fan off or near off.
- Ventilate: ABS releases styrene fumes while printing.

Questions about ABS
What temperature should I print ABS at?
Nozzle 240–270 °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 ABS are in a 1 kg spool?
About 400 m at 1.75 mm (density 1.04 g/cm³). One metre weighs 2.50 g.
Does ABS need drying?
Rarely for fresh spools. ABS absorbs moisture slowly; dry at 70 °C for 6 hours if it has been open for months or prints with unexpected stringing.
How much does ABS shrink?
About 0.8% linear. To compensate, scale X and Y by 100.81% in the slicer, or measure a test print and use the shrinkage calculator.
