Result description
L-PBF as-built samples meet the partner specifications in terms of Young modulus, Tensile Strength, Yield Strength and elongation. Dimensional accuracy of the parts was validated thanks to a good coupling with the power tool. They also performed well under torsion static test and their fatigue performances were confirmed with 200.000 loading cycles without failure. The study also showed that a 87% reduction of CO2 emissions can be reached thanks to 90% powder recycling. Consumption measurements (gas-flow, electricity consumption) were performed during the 3D-printing operation.
