Abstract
A method of fabricating a part by additive fabrication, in particular by melting or sintering particles of powder by means of a high energy beam. The method includes supplying a digital model of a part to be fabricated; orienting the model relative to a construction direction for constructing the part; modifying the model by adding a sacrificial balancing fraction configured so as to balance the residual stresses that appear in the part while it is being fabricated; making a rough part layer by layer using an additive fabrication technique on the basis of the model as modified in this way, the layers being stacked in the construction direction; and using a material-removal method to eliminate the sacrificial portion from the rough part as results from the sacrificial balancing fraction of the model, thereby obtaining the part that is to be fabricated.
