HEX #000000TD 0.3
PETG sits between PLA and ABS. It's durable and impact-resistant like ABS, but you can print it without an enclosure or fume handling. Black PETG is made from virgin PETG copolyester.
Key properties
- Durable, impact-resistant and temperature-resistant
- No enclosure required
- Can't be acetone-smoothed (unlike ABS)
Printing notes
- PETG bonds very strongly to glass and smooth PEI. Use a release agent such as a glue stick or WELD3D, or the print or the build plate can break when you remove it.
- PETG absorbs moisture. Store it sealed with desiccant, and dry it if you hear popping.
Specs
- Base resin: virgin PETG copolyester
