PLA vs PETG 3D Printing
PLA is the easiest filament to print and great for detail; PETG adds toughness, flexibility and water/chemical resistance while staying relatively easy to print — a popular middle ground.
| PLA | PETG | |
|---|---|---|
| Printability | Easiest; crisp detail | Easy-ish; can string, likes tuning |
| Durability | Rigid, brittle under impact | Tough, slightly flexible, impact-resistant |
| Heat & chemicals | Low heat tolerance | Better heat + water/chemical resistance |
| Best for | Models, prototypes, fine detail | Functional parts, outdoor, mechanical |
Choose PETG
Choose PETG when you need durability, a little flex, or moisture resistance.
