On November 5, SOLIZE PARTNERS and NTT DATA ZAM Technology announced the signing of a Memorandum of Collaboration on AM Business, establishing a strategic partnership to create an additive manufacturing (AM) mass production market and jointly drive Japan's AM industry from prototyping toward mass production. The two companies have complementary capabilities. SOLIZE PARTNERS brings a customer base centered on the automotive industry, end-to-end support from design and analysis through prototyping and low-volume production, and more than 35 years of accumulated AM business experience with a proven track record in polymer AM. NTT DATA ZAM Technology contributes the introduction and maintenance of EOS AM systems (polymer and metal), development of metal AM applications, materials, and build processes, contract manufacturing with quality assurance, and mass production technical support, along with a track record in the space sector. Both are leading-scale players in Japan's domestic AM market. The collaboration covers three areas: joint proposals in polymer and metal AM mass production, seamless support from design and development through to production deployment, and the creation of concrete AM mass production cases and market expansion through joint proposals. Value for buyers: the merger of Japan's two leading players in polymer AM and metal AM strengthens mass production engineering capabilities and the EOS metal equipment channel (NTT DATA ZAM will also begin domestic sales of EOS's new metal 3D printer, the EOS M4 ONYX, from Q1 2026). This represents a competitive signal for Chinese AM equipment and powder suppliers entering the Japanese market and is worth monitoring.
