Product designers and engineerswould create makeshift proof-of-concept models with basic tools, but producing functional prototypes and production-quality parts often required the same processes as finished products. Traditionalmanufacturing processeslike injection molding require costly tooling and setup, which...
Modern 3D printers are advanced enough to create complex structures and geometries that would be otherwise impossible to build manually. They can be used to build a range of objects, from simple prototypes to intricate final products, such as medical instruments, aircraft parts, eco-friendly buildin...
As aplastic, polypropylene is blow-molded into bottles for foods, shampoos, and other household liquids. It is also injection-molded into many products, such as appliance housings, dishwasher-proof food containers, toys, automobilebatterycasings, and outdoor furniture. When a thin section of molded...
