3D design and study on fatigue specimens for metal printing
Design study and work were carried out for the MAM baseplate. For IN718 and Ti-6Al-4V, manufactured with SLM 280 2.0. With power up to 400W, 0.03mm layer thickness and varied hatching distance and velocity, two baseplates of the same design were produced for testing, while more design was created an...
