CPE - Co-Polyester
Technical polyester with strong chemical resistance and cleaner printing.

About the material
CPE is a technical co-polyester often seen as a higher-performance alternative to standard PETG in demanding use. Properties: - Better heat resistance than typical PETG - Good chemical resistance and dimensional stability - Usually less stringing than poorly tuned PETG profiles Best for: chemical-contact parts, warmer environments, transparent or technical covers. Related: PETG, Filament, Chemical Resistance.
Pros
- ✓Improved heat resistance over many PETG profiles
- ✓Good chemical durability
- ✓Can print cleaner with reduced stringing when tuned
Cons
- ✗Usually costs more than standard PETG
- ✗Less common profiles and community tuning guides
Best for
- •Chemical containers
- •Heat-exposed components
- •Technical covers
- •Functional transparent parts
