(57) Abstract:
The disclosed invention resolves the problem of manufacturing three-dimensional objects by stacking two-dimensional
layers of material in the third direction z. Described are a machine and a method for additive manufacturing of three-dimensional objects
in which a predetermined final object is fabricated using the steps of the printing process (100) of individual curved three-dimensional
print volumes (1, 2, 3...Z) in a sequence (51). Powdered material (102) is melted in a melting volume (280) which is inside an intersection
volume (28) and in which the energy exerted by at least two particle clusters (160,170) emitted from at least two spatially positioned
sources (11, 12) of particles with mass adds up and exceeds the threshold required for melting of the powdered material. Machine and
method according to the disclosed invention enable the fabrication in multiple different printing directions simultaneously.
