Fast, Ultra-Precise Metal 3D Printing Using PureForm™

PureForm from Greene Group Industries is a proprietary metal 3D printing technology that can produce rapid-prototyping, production, and replacement parts without compromising quality.

Leverage the PureForm Advantage

Fast metal printing is a low-cost option with no molds or time delays. PureForm 3D printing delivers prototype metal parts with surface finishes and feature resolution comparable to those of metal injection molding.

Utilizing PureForm metal additive manufacturing enables you to:

Save time and reduce time-to-market by bypassing the lengthy process of mold construction

Achieve surface finish and feature resolution beyond other additive manufacturing technologies

Scale quickly and economically for low-volume production runs

Easily transition to metal injection molding (MIM)

PureForm metal 3D printing utilizes a unique mixture of MIM powder and a photoresistive polymer binder to deliver complex, precision metal parts when you need them.

A Streamlined Path from Prototype to Production

Additive metal 3D printing with PureForm is a competitive advantage that helps you rapidly prototype and refine, enabling you to solve technical challenges and bring new products to market faster.

Complex metal components, on demand

In the PureForm metal 3D printing process, components are constructed layer by layer using specialized high-resolution, high-throughput optical printers. The subsequent “green state” components are then processed through debinding and sintering, yielding parts that comply with MPIF-35 standards. The backend process is virtually identical to MIM.

  • Production metals include 17-4PH stainless steel and 316 stainless steel
  • Produce components with features as fine as 50 microns with 100-micron walls
  • Options for post-sinter secondary processes (plastic over molding, machining, grinding, brazing, welding, crimping, assembly, etc.)

PureForm™ Metal 3D Printing Design Guidelines

Greene Group Industries’ PureForm additive manufacturing platform uses Digital Light Processing to produce intricate metal parts at production scale. The H200 industrial printer grows a batch of parts layer-by-layer by curing a slurry that mixes metal particles with a highly reactive photopolymer.

What Our Customers Say

“GGI has been a 5-star partner for us. After working with GGI through several projects over 6 years, I have found them to be incredibly responsive, and they have provided us with unparalleled quality on some of the most challenging MIM components. GGI has consistently developed novel ways to design their tooling to meet our demanding specifications on the latest surgical technology.”

Sr. Manufacturing Engineer,

Large Medical Device OEM

“GGI has remained a top-tier supplier long term. The highest levels of responsiveness and professionalism set them apart in support of rapidly changing requirements and extremely dynamic end customer requirements. Much of our success ties directly into these very high levels of support. Continuing thanks to GGI for all the support over all these years.”

Purchasing Manager,

Leading Equipment and Systems Manufacturer

“I wanted also to share that if I am ever asked to rank all of the vendors I have worked with according to responsiveness, achieving goals, communication, skill, and overall medical product knowledge, GGI wins, hands down. It is a pleasure seeing the project turn into a trusted process. Thanks to you both and your team!!!!”

Design Assurance Engineer,

Large Medical Device OEM

“Over the past several years GGI has worked with my project team to develop components for multiple innovative new devices. The complex nature of our designs makes these projects challenging and require a lot of personal attention, crisp communication, and creative problem-solving to meet our project targets of timing, cost, and superior quality. GGI has demonstrated their willingness and ability to deliver in these areas, making them a valued partner for our business.”

Director of Advanced Instruments

Large Medical Device OEM

“GGI’s project management support is the best of any MIM house we have worked with. We are confident when placing a new tooling PO with GGI that we are going to close the project on time. When we get into production, GGI partners with us to continually improve the process and cost over time. We ask GGI to help us compete and they are always there looking for new ways help us to advance.”

Sr. Buyer

Large Medical Device OEM

“GGI rapidly develops complex machined components and assemblies with the highest possible quality. They take on our most challenging parts right from the prototyping stages, support all development efforts and carry them through to production seamlessly. They support our development efforts as if they are part of the internal team and their level of communication is superb.

GGI has been essential to product success and bringing the highest possible quality devices to the customer. They take on real challenges and work to solve them, not only with highly precise machined parts but with a range of processes and capabilities.”
