3D printing materials are the raw materials used by a 3D printer to create a physical object. The most common materials used for 3D printing are plastics, such as PLA and nylon. PLA (Polylactic Acid) is a popular material that is biodegradable and derived from renewable resources such as corn starch or sugar cane. It is often used for prototypes, toys, and figurines due to its low cost and ease of use. Nylon, on the other hand, is a popular material for its strength, durability, and flexibility, and is often used for functional parts and prototypes. Each material has its own unique properties, such as temperature resistance, stiffness, and color options. It’s important to choose the right material for your specific application to ensure the best results.
