SPAR3D

Research, study and demonstration of strategies to obtain profitable metal spare parts in additive manufacturing processes for the automotive industry.

The SPAR3D project focuses on additive manufacturing (AM) or 3D printing, a disruptive technology that is increasingly used in the manufacturing and repair of metal parts.

SPAR3D proposes an integrated process route that covers the additive manufacturing process itself and the subsequent treatments coupled to metallic materials (steel and aluminum).

In the project, steels and aluminum alloys are designed and manufactured using L-PBF technology and MEX-HP techniques, generating fundamental knowledge about metallurgy and the evolution of the microstructure in the time-temperature history characteristic of AM.

On the other hand, SPAR3D studies and optimizes post-processing treatments to improve mechanical response in working conditions similar to the operating conditions of spare parts obtained through 3D printing.

Additionally, the project optimizes advanced characterization techniques to evaluate the fatigue behavior and other relevant properties of 3D printed components.

Eurecat participates in SPAR3D through its Metallic and Ceramic Materials Unit, in charge of designing new aluminium alloys for AM based on the L-PBF technology and developing new advanced characterization methods for AM metallic alloys.

During the project, a new rapid testing method to assess the fatigue properties of AM alloys in a reduced time is optimized, which will allow for a significant reduction of costs. Furthermore, other relevant parameters for these kinds of alloys are studied, such as the effect of the surface finishing on mechanical properties and their hydrogen embrittlement susceptibility.
