Industrial 3D printing materials manufacturer 6K Additive has completed an initial public offering on the Australian Securities Exchange (ASX), raising A$48 million through the sale of CHESS Depositary Interests (CDI) priced at A$1.00 each.
At that offer price, the company entered the public market with an initial market capitalization of approximately A$267 million and an enterprise value of about A$206 million. The CDIs are trading on the ASX under the ticker symbol 6KA.
The offering included new institutional investors, family offices, and other sophisticated investors in Australia and overseas, alongside existing shareholders. The proceeds are intended to support an expansion program to increase production capacity and supply metal powders and alloy additions to aerospace, defense, space, medical, energy, and automotive markets.
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.”
Capital supports production scale-up
The IPO funding complements a US$23.4 million grant awarded to the company under the US Department of Defense (DoD) Production Act Title III. Taken together, the equity proceeds and grant funding are expected to increase metal powder production capacity from about 200 to approximately 1,000 metric tons annually and enable the start of commercial ingot production.
Work related to this expansion is already underway at the company’s 45-acre global headquarters site in Burgettstown, Pennsylvania. The project includes expanding existing powder production operations to accommodate up to 10 additional UniMelt plasma systems, constructing new facilities for feedstock preparation and ingot melting, and building a dedicated refractory production facility.
The company’s capital structure has been further bolstered by the recent approval of a US$27.4 million long-term loan facility from the Export-Import (EXIM) Bank of the United States. The EXIM loan builds on the previously awarded DPA Title III grant and is intended to help finance the construction of four new buildings and the acquisition of equipment used to produce titanium and nickel powders and alloy additions.
With funding in place from the IPO, the DPA grant, and the EXIM loan, 6K Additive said it plans to complete its near-term Burgettstown expansion on schedule, invest in additional plasma and downstream equipment to increase titanium and high-performance nickel alloy powder production, and pursue growth opportunities with aerospace, defense, energy, and industrial clients.
On the commercial side, the manufacturer reported a US$240 million sales pipeline as of the end of November 2025, an increase of approximately US$10 million over the prior two months. 6K Additive said expanded production capacity and improvements to operating metrics are intended to support anticipated demand once construction is completed and additional equipment is placed into service.
IPO activity across 3D printing sector
Public listings have become more common across the 3D printing sector as companies look to raise additional capital.
For instance, California-based metal 3D printer manufacturer Velo3D listed on the Nasdaq after offering 5,833,333 shares at $3.00 apiece, raising $17.5 million. The company said the funds will be used for working capital, capital spending, and general corporate purposes.
Trading under the ticker VELO, the listing moves Velo3D from the OTCQX market, where it previously traded as VLDX, after having earlier traded on New York Stock Exchange (NYSE) before being delisted in September 2024 for failing to meet ongoing listing requirements.
Separately, California-based medtech firm Carlsmed Inc. completed an initial public offering that generated approximately $100.5 million in gross proceeds. Carlsmed began trading on the Nasdaq on July 23 after pricing 6.7 million shares at $15.00 each under the ticker CARL, with underwriters granted a 30-day option to purchase up to an additional 1,005,000 shares.
The company said the IPO funds will support manufacturing scale-up, commercial expansion, and further development of its aprevo platform for 3D printed personalized spine surgery.
