Epson and DBJ invest in U.S.-based 3DEO to promote additive manufacturing

Supporting advanced metal 3D printing technology

Seiko Epson (“Epson”) and the Development Bank of Japan (“DBJ”) have jointly invested in 3DEO, a California-based startup specializing in metal additive manufacturing (AM). 3DEO offers fully integrated services, combining patented 3D printing hardware and software, to enable the design and production of complex metal parts.

Through partnerships focused on design for additive manufacturing (DfAM), 3DEO helps accelerate the development of competitive products in industries such as aerospace, medical/healthcare, semiconductors, and industrial equipment.

Bridging global innovation and Japan’s manufacturing landscape

The adoption of metal AM has been expanding globally in recent years, especially in high-performance industries seeking faster development cycles, reduced costs, and lightweight designs. Applications have broadened to include automotive and industrial tooling, such as spare parts and functional molds.

In contrast, Japan’s manufacturing sector still heavily relies on traditional precision casting and machining, which has historically supported high-quality supply chains. While R&D efforts around AM and DfAM are ongoing, the implementation of such technologies at production sites has faced high entry barriers, slowing broader adoption.

Strategic investment for innovation and competitiveness

This investment reflects DBJ’s mission to promote technological innovation and industrial transformation, and aligns with Epson’s vision of “manufacturing innovation” under its Epson 25 Renewed Corporate Vision.

The funding was provided via the DBJ Startups and Innovation Fund, part of DBJ’s Specified Investment Operations, with the goal of supporting 3DEO’s expansion in North America and Japan while contributing to enhancing innovation and competitiveness in Japanese manufacturing.
