Yes. PLA can be sanded, filled, primed, and painted easily.

PLA is moisture-resistant but not waterproof over long periods.

PLA offers excellent dimensional accuracy and is ideal when tight tolerances and sharp detail are required.

No. PLA degrades with UV exposure and heat and is not recommended outdoors.

No. PLA softens at relatively low temperatures (around 55–60 °C). It is not suitable for hot environments, car interiors, or near motors.

PLA is stiff but brittle. It works for light-duty functional parts but is not suitable for impact, flexing, or load-bearing applications.

PLA is best for prototypes, visual models, jigs, fixtures, and parts where dimensional accuracy and surface finish matter more than heat or impact resistance.
