ADDMAN Deepens Space Industry and Refractory Metals Expertise Via Castheon Acquisition

Bonita Springs, FL Jan 3, 2022: ADDMAN Engineering (“ADDMAN”) announced that it has acquired Castheon Inc. (“Castheon” or “Company”), a leading provider of additive manufacturing technologies for mission-critical space applications.

Founded in 2016 by Dr. Youping Gao, Castheon is an innovative developer of additive manufacturing processes and a leading metals additive manufacturer for demanding end markets. The Company has deep expertise in metals printing and has developed processes that promise to meaningfully expand the use of traditionally difficult to manufacture refractory metals. Castheon partners with next generation spacecraft companies to design, develop, and print complex components with quick turnaround times.

“This investment affirms ADDMAN’s strategic proposition in space. We believe that the technologies created by Dr. Gao will revolutionize the additive manufacturing industry and transform thinking around component development for the end markets that Castheon serves. Dr. Gao’s accomplishments represent the cutting-edge of additive manufacturing, especially in refractory metals applications and solutions for the space industry,” said Joe Calmese, ADDMAN CEO.

Dr. Gao added, “Castheon has made major breakthroughs in technology to print refractory metals, including demonstrated success in difficult applications such as reaction control system (“RCS”) thrusters for spacecraft customers. Castheon’s technology and know-how, combined with ADDMAN’s scale and resources, will supercharge the next chapter of Castheon’s growth. ADDMAN brings a national manufacturing and engineering footprint with over 300 employees, dozens of additive manufacturing machines and key quality certifications, and over 100 traditional subtractive machines to Castheon’s customer base.”

Kevin Wilken, Partner at AIP, commented, “The ability to efficiently produce certain refractory metals via additive manufacturing is a breakthrough for customers who depend on high temperature structural components. Castheon’s offerings, which include solutions to print Niobium and other refractory metals, have the potential to transform the way additive serves advanced industries. AIP is fully committed to support the continued growth of the combined company.” Mr. Wilken added, “We welcome Dr. Gao to the ADDMAN team and look forward to delivering innovative solutions that enable our customers’ success.”

Castheon is ADDMAN’s 3rd acquisition in 10 months.
