Holo, a metal Additive Manufacturing company headquartered in Newark, California, USA, has launched PureForm™ MicroAM, a high-resolution Additive Manufacturing platform capable of processing copper, stainless steel and other metals.

Based on a Vat Photopolymerisation (VPP) process, PureForm MicroAM can produce parts with features less than 50 µm, enabling a wide range of applications including electrical components, jewellery, and medical and dental devices.

“Traditional manufacturing approaches, such as Swiss CNC, moulding and casting are either too costly for volume production or cannot produce complex parts with such fine features,” stated Hal Zarem, Holo’s CEO. “PureForm MicroAM enables our customers to access parts at a lower cost and produce geometries that cannot be made any other way.”

Holo introduced its PureForm technology earlier this year and is ramping up its 1900 m2 production facility in the San Francisco Bay Area where it has capacity to produce tens of thousands of parts per month.

PureForm MicroAM is already said to have unlocked capabilities for customers in the electronics industry, producing fine-featured micro inductors coils, built with 400 µm strands and in high-end custom jewellery.

Simon Evans, Senior Manager, Diamond Center Wales, commented, “We’ve been blown away by the resolution and surface quality of the parts Holo can produce and are excited to explore the direct metal printing of jewellery with them. Leveraging the design freedom of additive and the fine features of PureForm will allow us to create truly unique, custom pieces for our clients that couldn’t be made using other manufacturing processes.”

Other AM applications that have been enabled by PureForm MicroAM include stainless steel biopsy scoops used in medical applications with sharp point features, down to 20 µm and dental abutments with additively manufactured functional threads that hold a 200 µm pitch.

Arian Aghababaie, co-founder and Chief Strategy Officer, Holo, added, “We are excited to continue to offer new capabilities to our customers, enabling us to support a host of new MicroAM applications, from surgical equipment and dental, to micro-electronics, micro-robotics, consumer electronics and jewellery.”

Series B investment

In addition to introducing its PureForm MicroAM, Holo has added two new investors, Lam Capital and Atreides Management, to its Series B investment round. The round included participation from existing investors Prelude Ventures, Tao Capital Partners and Lightspeed Venture Partners.

Upon the closing of its latest financing round, Holo states that it plans to grow significantly in 2021 and 2022, doubling the size of the company, accelerating the development of its 3,000 cm3/hr high throughput production system and continuing to expand its materials portfolio.

Spun out of Autodesk in 2017, Holo was co-founded by the team that developed and led Autodesk’s Ember Additive Manufacturing product.
