3D Spark expands investor base for AI platform for manufacturing optimization

The Hamburg-based startup 3D Spark has completed a new, privately placed funding round and is bringing on board a number of experienced industry figures as angel investors and advisors. The company is developing an AI-powered platform that supports manufacturers in selecting suitable production processes, as well as in cost calculation, lead time estimation and CO₂ footprint – with a focus on additive manufacturing. Following a two-million-euro seed round at the beginning of the year, this current community investment is intended primarily to expand the network rather than the capital base.

“This round was about more than funding – it was about building a community around our mission,” said Ruben Meuth, Founder and CEO of 3D Spark. “We’re honored to have such outstanding leaders from industry, research, and entrepreneurship join us in driving more efficient, sustainable, and digital manufacturing globally.”

The new supporters include, among others, former executives from Siemens, SLM Solutions and Airbus, as well as researchers from the environment of Fraunhofer IAPT and Helmut Schmidt University. They contribute expertise in laser and additive technologies, smart factory, software scaling and international sales.

Technically, 3D Spark targets companies that want to automatically check the manufacturability of parts early in the development process – initially focusing on 3D printing. The software evaluates geometries, materials and batch sizes and provides recommendations on whether, for example, laser powder bed fusion, binder jetting, conventional machining or sheet metal processing is more economical. The goal is to reduce scrap and manual quotation rounds while at the same time providing robust data for decision-making in purchasing, design and sustainability reporting.

With the expanded advisory circle, 3D Spark plans to enter additional industries beyond its currently strong rail vehicle segment and to cover further manufacturing technologies in addition to additive processes. Market entry in the USA is also on the agenda. At Formnext 2025, the team plans to demonstrate at Booth 12.1 D72 how the platform can be used to reduce manufacturing costs, lead times and emissions in both 3D printing and conventional production.
