1. Additive manufacturing technologies
Material consolidation can be achieved by material deposition or by selective consolidation of a previously deposited material. Material deposition can be achieved by extrusion-deposition of a bead or by droplet projection. Selective consolidation involves scanning an energy beam (laser, electron or ion) through a bath of powder or liquid.
1.1 Material deposition additive manufacturing
Material deposition is the most natural printing method in additive manufacturing. Before the material is deposited, it needs to be brought into a "malleable" state, because after deposition, the new volume of material needs to "anchor" onto the previously deposited material. Coalescence is necessary to ensure this cohesion. The layer of material receiving the deposit must also...
