You've mastered PLA and you're ready to try something new. PETG is the natural next step — but how does it compare? Here's a practical breakdown.
The Quick Answer
- Use PLA for decorative prints, prototypes, toys, and anything that won't be exposed to heat or stress
- Use PETG for functional parts, mechanical components, outdoor use, or anything that needs to be tougher or more flexible
PLA vs PETG: Side-by-Side Comparison
| Property | PLA | PETG |
|---|---|---|
| Ease of printing | Very easy | Easy |
| Strength | Moderate | High |
| Flexibility | Brittle | Slightly flexible |
| Heat resistance | Low (~60°C) | Medium (~80°C) |
| Warping | Very low | Low |
| Print temperature | 190–220°C | 220–245°C |
| Food safety | Not recommended | Some grades are food-safe |
When to Choose PETG
- Phone cases or protective covers
- Mechanical parts like hinges, clips, or brackets
- Outdoor items exposed to sunlight or moisture
- Containers or bottles (food-safe grades)
- Anything that might be dropped or stressed
PETG Printing Tips
- Print slightly slower than PLA for better layer adhesion
- PETG sticks very well — use a release agent or PEI sheet to avoid it bonding too strongly to the bed
- Reduce cooling fan speed compared to PLA
- Dry your filament if you see stringing — PETG is more moisture-sensitive than PLA
We carry PETG in 16 colors including transparent options in clear, blue, green, and orange. Compatible with most FDM printers including the EasyThreed K7 and K9.
