When PLA is the right choice
- Concept models and visual prototypes
- Fit checks against other parts
- Display pieces, architectural and presentation models
- Indoor fixtures and organisers that see light loads
When to choose something else
- Heat: PLA can deform in a hot car or near warm electronics. Use PETG or ABS/ASA.
- Impact and flexing: PLA tends to snap rather than bend. Use PETG or nylon.
- Outdoors: Use ASA.
Questions
Is PLA strong?+
PLA is stiff and fairly strong in tension, but brittle under impact and weak at elevated temperatures. For functional parts, PETG, ABS/ASA, or nylon are usually better.
Can PLA parts be used outdoors?+
It isn't recommended. PLA softens in heat and degrades in UV and weather over time. ASA is the outdoor choice.
