Additive Manufacturing Services

GPI Prototype uses a variety of cutting-edge additive manufacturing technologies to produce plastic and metal parts in a wide range of materials. The additive manufacturing processes used to create parts rapidly impact product design and development time cycles, resulting in significant time and cost savings. Notable additive manufacturing services include Direct Metal Laser Sintering (DMLS), 3D printing, Stereolithography (SLA), Selective Laser Sintering (SLS) and Fused Deposition Modeling (FDM). These technologies build directly from CAD data, and are ideal for low to mid volume production of metal and plastic components.

Additive Manufacturing Services Include:

Metal 3D Printing also known as DMLS/DMLM is an additive manufacturing technology that provides high precision metal parts. The layer additive process is suitable for all industries requiring custom fast turnaround metal parts. Production injection molding tooling created offers injection molding companies extended possibilities for high performance manufacturing. This design freedom allows the integration of conformal cooling channels, which improve the quality and speed of injection molded parts.


3D Printing (3DP) is a rapid prototyping technology that provides high precision plastic 3D models. The layer additive process is suitable for proof of concept models and inexpensive prototypes of new products.

Stereolithography (SLA) produces accurate models from a wide range of UV curable resins, comparable to ABS, Polycarbonate and Polypropylene. The resulting prototypes are suitable for form, fit and function testing as well as urethane casting patterns.

Fused Deposition Modeling (FDM) is a rapid prototyping and additive manufacturing technology that can produce ABS, PC and ABS/PC parts without the need of expensive tooling. This is ideal for short run parts with quick turnaround times.

Selective Laser Sintering (SLS), provides accurate models from sintered nylon powder. They can be used for form, fit and function testing as well as limited run production. This process is ideal for complex parts as supports are not needed during the build process.
