Although, injection molding and 3D printing are distinct processes – Mainly they are used in manufacturing. Plastic products Manufacturing , Auto Parts Manufacturing etc.
Prototyping: 3D printing is commonly used to create prototypes of parts before investing in injection molding tooling. It allows for faster iteration and design validation,
reducing costs and time associated with traditional mold making.
Mold Manufacturing: 3D printing can be used to produce molds or mold inserts for injection molding. This approach, known as rapid tooling or bridge tooling, enables faster turnaround times for mold production, especially for low-volume production runs.
Injection mould are used in heavy Injection mould Machines where molten materials are injected on high pressure inside the mould to produce desired products. After cooling down the products become hard and ready to use.
