Injection molding is a traditional manufacturing process that involves injecting molten material into a mold to produce parts. In 3D printing, the term injection molding is often used to describe a similar process, which involves injecting molten plastic into a 3D printed mold. This allows for the production of complex parts with intricate details that may be difficult to achieve with traditional 3D printing methods. The process can be used for both small and large production runs and offers a cost-effective solution for producing high-quality parts. While 3D printing injection molding requires specialized equipment and materials, it is becoming an increasingly popular manufacturing method for producing parts for a variety of industries, including aerospace, automotive, and consumer goods.
