MIM Producer Greene Group Industries Acquires Holo's Intricate Metal 3D Printing Assets

Greene Group Industries (GGI) has finalized a deal to buy out Holo’s resources. Holo, an Autodesk detachment, has been a frontrunner in large-scale digital production of complex metal pieces. Even though exact details of the agreement remain undisclosed, it has been revealed that GGI has bought Holo’s patented PureForm additive manufacturing tech, known for swift prototyping and the mass production of multifaceted metal components.

Throughout its centennial history, GGI’s expertise lies in delivering superior metal parts and services. It’s a proven leader in various metal shaping technologies like stamping, forming, CNC machining, wire electrical discharge machining (EDM), and metal injection molding (MIM). Their advanced manufacturing, sales, and support chain enable them to convert a primary product concept into a fast prototype followed by a short-run production process.

Prior to procuring Holo’s resources, GGI had allied strategically with a private equity company based out of New York, called Tinicum LP. It gets its monetary inflows on behalf of the Ruttenberg family, acknowledged for their influential presence in investment endeavors since 1940s. Alongside funds supervised by Tinicum Incorporated, Tinicum LP has bought a major interest in GGI with an ambition to fasten the pace of tech investments, enhance capabilities, and cater to the growing needs of global clients. As a result of this partnership, GGI can exploit Tinicum’s proficiency in industrial technologies and draw from the rich investment history of the Ruttenberg family.

“This new technology from Holo is a great complement to our vast offerings of metal injection molding, stamping, and accuracy-based machining. By enabling GGI to deliver prototype metal parts that are comparable to metal injection molding in terms of surface finish and feature precision, this deal ensures best-in-class delivery times of less than a fortnight,” said Alexis Willingham, GGI’s CEO. “The PureForm additive manufacturing technology bolsters our rapport with clients. It helps expedite iterations across the product lifecycle while allowing GGI to uphold its unparalleled engineering service and quality output.”

Holo’s flagship PureForm, additive manufacturing technology, uses a proprietary slurry consisting of MIM powder and a photoresistive polymer binder. This innovative approach allows for the construction of parts layer by layer using high-resolution, high-throughput optical printers specially developed by Holo. Initially, the parts are created in a “green state,” containing the binder material. This binder is then eliminated during a sintering process in a high-temperature oven, ensuring the densification of the parts and imparting strength, resulting in final products with qualities that closely mimic those of bulk materials. The PureForm technology facilitates rapid prototyping and the scaled production of complex designs that are challenging to achieve with traditional manufacturing methods. It is ideal for aerospace, automotive, medical, electronics, and industrial sectors.

Additionally, the result of the printing process is a green part that mixes metal particles and polymer binders. Subsequent processes de-bind the polymer and then combine the metal particles to form completely dense metal parts. This process is familiar in the industry and resembles the standard process used in various 3D printing technologies.

“The backend process is virtually identical to MIM,” as Holo states. This means that PureForm uses the same process as metal injection molding (MIM), where the polymer binder is removed, and the metal particles are sintered together to form fully dense metal parts.

Furthermore, PureForm uses MIM powder in its special metal-polymer mixture, which means it can potentially print metal items in various MIM powders. This makes PureForm different from regular MIM methods since it doesn’t need molds, it makes parts with surface finishes and details that meet or beat MIM standards, there’s no need for extra work after printing, and it can handle larger production volumes, making tens of thousands of parts each month possible. For large-scale production, Holo recommends traditional MIM processes, suggesting PureForm users consider designs compatible with injection molding for scalability.

Founded as a spinout from Autodesk and backed by top-tier Silicon Valley investors and strategic partners, Holo’s proprietary digital manufacturing platform produces high-resolution parts across a wide range of material classes, including metals, ceramics, and composites.

With the acquisition of Holo’s assets, GGI not only brings the innovative PureForm technology into its operations but also gains control over key aspects of Holo’s technology and intellectual property, including expertise in rapid prototyping, scaled production, and achieving surface finishes similar to metal injection molding. This integration will enhance GGI’s capabilities, setting higher standards for efficiency and quality in the industry and offering customers improved services, faster lead times, and an expanded array of metal-forming solutions.
