Plastic 3D Printing
Plastic 3D printing is the most developed form of 3D printing, and it offers the widest variety of materials. For 3D printing professionals, ABS, polypropylene, Nylon, and high temperature plastics such as polyetherimide are among the most popular. Most plastic 3D printing requires curing and post-processing, but it can still reduce lead times by weeks compared to traditional fabrication.
Acrylonitrile butadiene styrene (ABS): an all-around popular choice, providing good aesthetics and a balanced spread of mechanical properties. Found in toys, kitchen appliances, telephones, and other everyday products.
Polypropylene (PP): cheap, chemical resistant, and able to form living hinges, yet flammable and degrades with UV light. Household containers, lab equipment, and textiles are made with PP.
Nylon: strong, rigid, and durable, yet expensive and not resistant to strong acids and bases. Commonly found in under-the-hood components and other applications that require high mechanical properties.
Polyetherimide (PEI): 3D printing plastic designed to withstand high heats. This material makes good injection mold tools and heat-resistant components, but it comes with a hefty price tag.
