Choose PLA when
You want a clean indoor prototype, display model, organiser, spacer, enclosure mock-up or hobby item. PLA is often the most economical place to start when heat and repeated impact are not important.

PLA or PETG: which should you choose?
PartPact currently supports two useful everyday FDM materials. PLA is a dependable default for clean prototypes and indoor objects; PETG is often better when a practical part needs more toughness or temperature resistance.
Quick comparison
| Property | PLA | PETG |
|---|---|---|
| Print finish | Usually crisp and tidy | Often slightly glossier |
| Rigidity | Rigid and predictable | Tough with a little more flex |
| Heat resistance | Lower | Better for warmer everyday conditions |
| Impact behaviour | Can be more brittle | Generally more impact resistant |
| Typical use | Models, organisers, prototypes | Brackets, covers, functional parts |
Choose PETG when
The part needs more toughness, a little flex, or improved resistance to warmth and moisture. PETG can suit brackets, tool holders, covers and other non-critical functional parts.
Important limits
Material choice does not make a home-printed part certified or safe for every use. PartPact does not accept medical, food-contact, vehicle-safety, mains-electrical, weapon or other safety-critical jobs. Check the prohibited parts list before ordering.
