Bosch and Nikon SLM Solutions 3D Print a Full V8 Engine Block

Bosch Additive Solution Center in Nuremberg, Germany, has produced a complete V8 engine block as a single printed part. The component was manufactured in AlSi10Mg aluminum on a Nikon SLM Solutions NXG XII 600 laser powder bed fusion machine. The partners say the demonstrator proves additive manufacturing is ready for complex, high-value automotive applications.

Why a V8 block matters

A conventional V8 engine block requires tooling that takes weeks or months to develop. Design changes mean expensive tooling modifications. By printing the block directly from a digital file, the team eliminated that lead time entirely. The process also opened up geometries that casting cannot reliably achieve, including integrated cooling channels and topology-optimized structures.

The single-piece aluminum block is not headed for production, but it is a practical proof of concept. It shows that large-format metal AM can move beyond prototyping and into applications where weight, complexity, and lead time all matter.

What the partnership covers

The collaboration goes beyond a single machine installation. Nikon SLM Solutions provided the NXG XII 600 along with materials qualification, process parameter optimization, data preparation software, quality assurance, and application engineering. Bosch Industry Consulting contributed decades of automotive manufacturing expertise to assess how the demonstrator could translate into repeatable industrial production.

The two companies are targeting the tier 1 and tier 2 automotive supply networks. An estimated 60 to 80 percent of components in a finished vehicle are made by outside suppliers, not the OEM. By working with Bosch, Nikon SLM Solutions aims to move AM from capability to production reality at that level of the supply chain.

What comes next

The V8 block demonstrates that current metal AM systems can handle large, geometrically complex aluminum parts. The next step is qualification for repeat production runs. The partners believe the technology is ready, the workflows are in place, and the production systems exist to take complex aluminum components from design to finished part without castings, without tooling, and without the long lead times conventional manufacturing requires.
