Description Simulation: An extensive simulation phase is required and includes:
Macro-scale process simulation with AMTOP by ITACAe for the optimization of orientation, prediction of distortions and process time and costs;
Full-scale process simulation with GENOA by ALPHASTAR for the prediction of temperature, voids and stress distribution, mechanical properties of the 3d-printed part;
Mechanical test simulations.
Production and quality assesment: The production and experimental test phase includes: Components production with LPBF technology, AlSi10Mg material;
X-Ray Tomography for defects, porosity and deformation analysis; Experimental mechanical tests.
Model validation: This phase includes:
Methodology for numerical-experimental comparison;
Validation of numerical models.
