SLM is emerging as a key technologies for the production of functional metal prototypes, series parts and components in various industries. The SLM280 2.0 used by SZEngine features a build envelope of 280 x 280 x 365 mm3, along with a patented multi-beam technology.

As a pilot project, SZEngine began by printing the timing side of the two-part crankcase, although in total nine engine components were produced using SLM, including the cylinder, cylinder head and cylinder head cover, as well as the covers for the clutch, timing belt, oil filter and oil pump.

Following production on the SLM machine, the components were then mechanically processed and measured at the MAC. After being tested both individually and then together on the SZEngine team's test bench, the engine was installed in the team's test car.

Ralf Frohwerk, global head of business development at SLM Solutions, is pleased with the ground-breaking project: "Every day, our customers are placing greater trust in SLM technology. This impressive project from SZEngine and Audi Hungaria in Győr clearly shows that metal-based 3D printing is not just suitable for prototypes, but can also be deployed successfully for series production, especially small batches. The customer's experience in component design for 3D printing shows how additive manufacturing can enable improvements both in terms of function and performance.”
