Abstract

An apparatus for manufacturing a three-dimensional object by selective additive manufacturing comprises: a support () suitable for supporting at least one layer () of additive manufacturing powder, a laser source () suitable for emitting a laser beam (), a scanning device () suitable for directing the laser beam onto the powder layer so as to scan at least a portion of the powder layer, and a device () for modulating the scanning trajectory, arranged upstream of the scanning device, the modulating device comprising a modulating mirror () suitable for reflecting the laser beam emitted by the laser source and for directing it towards the scanning device, the angle of incidence of the laser beam emitted by the laser source on the modulating mirror being between 20 and 45°.
