PLA, or polylactic acid, is a popular 3D printing material known for its ease of use, low cost, and biodegradability. It is a thermoplastic material that is made from renewable resources such as cornstarch or sugarcane and is widely used in consumer products, food packaging, and medical implants.
PLA is compatible with FDM (fused deposition modeling) 3D printers and is widely available in filament form. It is a relatively easy material to print with and produces parts with good surface finish and dimensional accuracy. PLA is also biodegradable and environmentally friendly, making it a popular choice for eco-conscious users.
When printing with PLA, it is important to use a heated build platform or adhesive to ensure good adhesion of the first layer to prevent warping or curling of the printed part. PLA has a lower melting temperature than other materials such as ABS, so it can be prone to softening in high-temperature environments.
Overall, PLA is a useful material for producing low-cost, environmentally friendly parts with good surface finish and dimensional accuracy, making it a popular choice in a variety of industries and applications.
