PLA filament (Polylactic Acid filament) is a biodegradable thermoplastic derived from renewable resources like corn starch or sugarcane. Widely used in 3D printing, PLA is favored for its ease of use, low printing temperatures, and minimal warping. Although it is environmentally friendly and produces less odor during printing, PLA is less durable and heat-resistant compared to other filaments like ABS. Its moderate strength and rigidity make it suitable for prototyping, educational projects, and decorative items, but less ideal for functional parts requiring high impact resistance or flexibility. PLA's popularity stems from its accessibility and eco-friendly properties.
