PLA filament is a type of 3D printing material made from polylactic acid, a biodegradable plastic derived from renewable resources like corn starch or sugarcane. It is popular among hobbyists and professionals for its ease of use, low warping, and vibrant color options. This filament is ideal for creating prototypes, models, and decorative items. It prints at lower temperatures compared to other materials, making it compatible with a wide range of 3D printers. Additionally, PLA is known for its environmentally friendly properties, as it breaks down more easily than traditional plastics.
