Material comparison
Polycarbonate (PC) vs PETG
Both make tough, clear parts. Polycarbonate leads on impact and heat resistance; PETG is easier to form, lower cost and food/medical-friendly.
Polycarbonate (PC) vs PETG — side by side
| Polycarbonate (PC) | PETG | |
|---|---|---|
| Impact | Highest | High |
| Heat resistance | High (HDT ~127 °C) | Lower |
| Formability | Needs drying, higher temp | Easy, no whitening |
| Cost | Higher | Lower |
| Typical use | Guards, high-heat/impact covers | Medical, food, guards, displays |
Choose Polycarbonate (PC) when…
- Maximum impact and heat resistance
- Safety guards and demanding covers
Choose PETG when…
- Easy forming and lower cost
- Food and medical clear parts
- Deep draws without whitening
The verdict: Choose polycarbonate for the highest impact and heat resistance; choose PETG for easier forming, lower cost and food/medical clear parts.
