Abstract:
A component (1) is formed by means of additive manufacturing by repeating a series of cycles, where each cycle has a depositing step for forming a powder layer (22) of substantially constant thickness; a pre¬ heating step, for pre-heating the powder layer (22); and a melting step, for melting some areas of said powder layer (22) by means of an energy beam so as to form a horizontal section (170) of the component (1) that must be obtained; at the end of all cycles, the top surface (21) of the horizontal section that has been formed is lowered until it reaches a predetermined height (Q); the pre-heating step is performed by moving a heat source (30) above the powder layer (22) at the same time as the depositing step, at least for an initial part of the pre-heating step.
