PLA

PLA is one of the most common thermoplastics for FDM prototypes thanks to its low cost and easy printability.

Overview

PLA is one of the most accessible materials for FDM printing. It is a good starting point for visual prototypes, concept models, low-load parts, and fast iterations.

Troubleshooting

If the part will sit in sunlight or a warm environment, consider PETG, ABS, or an engineering-grade material instead of PLA. Leave tolerance around fitted surfaces and choose print orientation based on mechanical load.
