PETG is the friendly middle ground between PLA and ABS for FDM, and a useful alternative to ABS in injection molded packaging. Food-safe in standard grades, decent UV resistance, and clean processing.
Mechanical and physical properties

| Density | 1.27 g/cm³ |
| Modulus | 2.1 GPa |
| Max service temperature | 75 °C |
| Optical transmission | ~85% |
| Machinability rating | Average |
Typical applications
- Food and beverage packaging.
- FDM functional prototypes.
- Light fixture diffusers.
- Display cases and signage.
Why PETG over ABS
PETG prints with less warp, has better food contact certification, and is easier to glue. Choose ABS only when you need higher service temperature or solvent welding.
Specifying it on Uretyco
- 1Pick PETG from the dropdown
Clear or color stock for CNC; pellet grades for IM.
- 2Specify food contact if needed
Standard grade is FDA-compliant; specify on the order.
- 3Avoid acetone vapor smoothing
PETG does not respond to acetone; use heat polish or coatings.
- 4Plan for thicker walls
PETG is more flexible than ABS; over-engineer thin sections.
