With 27.2 million euros raised in its ASX IPO, 6K Additive is accelerating a major expansion in Pennsylvania, scaling metal-powder output and adding new production technologies.

Additive manufacturing company 6K Additive has made a strong debut on the Australian Securities Exchange (ASX), raising A$48 million (approx. 27.2 million euros) in an Initial Public Offering that values the advanced-materials producer at 151 million euros. Trading under the ticker 6KA, the company attracted broad support from institutional and sophisticated investors in Australia and abroad.

The new capital fully funds the company's expansion plan at its Burgettstown, Pennsylvania headquarters, supported by a previously announced 23.4 million dollars Defense Production Act Title III grant. The project — already under construction — will enable a fivefold increase in metal-powder output, taking capacity from roughly 200 to 1,000 metric tons per year. It will also consolidate facilities and add commercial ingot-melt capabilities, expanding 6K Additive’s product offering for aerospace, defense, energy, space, and medical markets.

The IPO follows last week’s approval of a 27.4 million dollars low-cost EXIM Loan, providing further flexibility for additional growth initiatives, including new buildings, feedstock operations, and advanced equipment for titanium and nickel-alloy production. Together, the IPO proceeds, federal grant and EXIM Loan position 6K Additive to meet rising demand and invest in additional Unimelt plasma systems and downstream processing infrastructure.

As of the end of November 2025, the company’s sales pipeline has grown to 240 million dollars, reflecting continued strong interest in its premium metal powders and alloy additions.

“The IPO and resulting capital fast-track the realization of our vision and achieve the scale with attractive unit economics and unique material breadth required by customers in defense, aerospace, energy, and medical markets,” said Frank Roberts, CEO and Managing Director of 6K Additive. “As a strategic supplier to the U.S. Department of War and its Tier-1 contractors, our products, production processes and technology have been qualified in their supply chains, reinforcing these relationships. This growth enables a domestic supply of critical materials for applications such as hypersonics, nuclear fusion, medical implants, and rocket-engine development.”

David Seldin, 6K Additive Chairman of the Board and Managing Partner of Anzu Partners commented, “As an institutional investor in 6K Additive from its inception, I witnessed this organisation grow to the leading domestic provider of metal powders and alloy additions. The breadth and quality of 6K Additive’s products, the trusted relationship with the US Department of War and the dedicated employee talent, underscores the potential this organization has in the coming 3-5 years.”
