Holo Welcomes John Buffington as Head of Product Engineering

Metal additive manufacturing company Holo scales commercial development with key product engineering leadership appointment.

John BuffingtonNEWARK, CA, USA, March 14, 2023 -- Holo, the metal additive manufacturing company, today announced the appointment of industry veteran John Buffington as the Head of Product Engineering. This leadership role will further solidify Holo’s momentum in scaling growth of metal part production and commercial delivery.

“Seeing how Holo is accelerating their customer’s development cycles, saving tooling costs, and providing them a smooth path from engineering development to production for complex and high-accuracy metal AM components, was an eye opener,” said Buffington. “I’m excited to be joining the already outstanding talents at Holo, providing our customers with dedicated support  and helping fulfill the promise of digital manufacturing of metal parts.”

Holo, which 3D prints highly-precise metal parts in prototype to production volumes for customers’ exacting requirements, is scaling capabilities and setting new expectations for additive manufacturing. In order to take its place in an increasingly noisy marketplace, the company is prioritizing a strong strategy as a focused vertical supplier built on its reliable, repeatable, and scalable manufacturing technology, PureForm™.

With the rapid growth Holo has experienced over the last year delivering True to CAD™ parts to customers, Buffington’s role in leading the Product Engineering function is a key decision for the company to continue its trajectory.

“Under John’s leadership, Product Engineering will continue to expand to meet the growth in demand from our customers, including Fortune 500 companies and leaders in the medical, consumer electronics, semiconductor, and other industries, to ensure rapid delivery of highly intricate metal parts, from engineering development through to volume production,” said Arian Aghababaie, PhD, Co-Founder, President, and Chief Strategy Officer, Holo.

Buffington joins Holo from a seven-year career at manufacturing solutions provider Jabil. As Senior Manager Engineering Services, Additive Manufacturing, Buffington worked to drive adoption of additive manufacturing as a viable solution for progressively larger opportunities at scaled production. The global focus at Jabil enabled a truly broad focus for what scalable additive manufacturing offers to an array of end users adopting advanced technologies.

"Coming from Jabil, John has extensive experience leveraging additive manufacturing to deliver high-quality products to the world's most demanding customers. This makes him a perfect fit for Holo. We are very excited to have him join us,” said Hal Zarem, CEO, Holo.

In addition to his tenure at Jabil, Buffington brings experience in engineering, development, and leadership from his years at battery case and accessory manufacturer mophie and speciality bearings producer RBC Bearings. These professional successes set him on a track to excel at Holo.

Holo’s PureForm technology produces parts with features less than 50 microns, holding tight tolerances across a wide variety of sizes. With this precision and MIM-like surface finish, Holo’s parts generally do not need post-processing, further reducing cost to the end customer. As demand continues to rise for complex metal parts, Holo is poised for growth.

Keeping up with the latest demands and advancements in what is technically possible with advanced metal additive manufacturing, Product Engineering needs are on the rise. Continuing to iterate on Holo’s offerings, Buffington will lead the team in developing state-of-the-art solutions to real-world customer needs in demanding end-use industries.

Holo will have a senior leadership presence next week at AMUG 2023. Meetings can be scheduled directly to meet with Aghababaie and VP of Sales Jason Bassi during the course of AMUG in Chicago at
