- PLA has a better surface finish, so PLA parts generally look better.
- ABS is more flexible, PLA is more brittle.
- ABS tends to warp more than PLA.
- ABS is soluble in acetone, making it “weldable.”
- PLA has less shrink, and tends to print more dimensionally accurate than ABS.
PLA is the more common material choice, so five of the six printers are dedicated to PLA.
