Questions about ASA
What temperature should I print ASA 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 ASA are in a 1 kg spool?
About 389 m at 1.75 mm (density 1.07 g/cm³). One metre weighs 2.57 g.
Does ASA need drying?
Rarely for fresh spools. ASA 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 ASA 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.
