ASA vs PC
Polymer · grade comparison
ASA and PC are both polymer grades, both multipurpose plastic. On the shop floor, PC sits in a lower cost tier (budget, $) than ASA (standard, $$).
PCChoose it when cost is the deciding factor.
ASA vs PC: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

ASA vs PC — frequently asked
What is the difference between ASA and PC?
ASA and PC are both polymer grades, both multipurpose plastic. On the shop floor, PC sits in a lower cost tier (budget, $) than ASA (standard, $$).
Which is cheaper, ASA or PC?
PC is the lower-cost material: it sits in the budget tier ($) while ASA is standard ($$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose ASA over PC?
Pick PC when cost is the deciding factor.
