PLA

PLA (Polylactic Acid) is a biodegradable thermoplastic. It is one of the most popular and widely used materials for FDM 3D printing due to its ease of use, low printing temperature, and good surface finish. PLA is ideal for rapid prototyping, offering decent mechanical properties with minimal warping or shrinkage.

Benefits

Good surface finish and dimensional accuracy

Wide variety of colors

Good stiffness and strength

Easy to print

Cost-effective

Limitations

Low heat resistance

Quite brittle

Poor UV and weather resistance

Low chemical resistance

Industries

PLA is primarily used in rapid prototyping, hobbyist projects, educational purposes, and decorative items. It is favored for concept models, visual prototypes, architectural models and toys due to its ease of use and aesthetic qualities. Its eco-friendliness also makes it popular in sectors focused on sustainability and green manufacturing, though it is less common for demanding mechanical or outdoor applications.
