GPI Prototype specializes in metal 3d printing and additive manufacturing services for rapid prototypes and short run manufacturing of complex parts. GPI was one of the first rapid prototyping companies in the United States offering Direct Metal Laser Sintering and has 6x DMLS machines from EOS and 4x direct metal printers from 3D Systems at their Lake Bluff, IL facility.

GPI Prototype started in 2007 offering prototypes using Objet 3d printing. As popularity grew for 3d printing services, an EOS M 270 metal 3d printer was added to the service offerings. Each year machines were added and capacity increased for metal 3d printing. In 2015, GPI Prototype decided to focus on metal additive manufacturing and remodeled part of the warehouse space into a showroom for their direct metal laser melting machines. We are now one of the largest privately owned service providers in the world for metal 3d printed parts and have the manufacturing capacity for large production orders.

Over the past 30 years our product development and prototype expertise have been utilized to support diverse and challenging projects. Today, GPI Prototype is taking all of its rapid prototype capabilities and offering them to every major industry.

GPI Prototype is ISO 9001:2015, ISO 13485:2016, AS9100D certified and ITAR registered.
