Frequently Asked Questions
Is CPE or ASA better for 3D printing?
ASA is generally rated higher (Tier A) compared to CPE (Tier null). However, the best choice depends on your specific needs: CPE is best for various applications, while ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between CPE and ASA?
CPE prints at 275°C nozzle / 90-110°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do CPE and ASA need an enclosure?
CPE: not needed. ASA: recommended.
Which is more beginner-friendly: CPE or ASA?
CPE is more beginner-friendly as it doesn't require an enclosure.
