The invention relates to a method for manufacturing an object (O) by solidifying powder using a laser beam, including at least the steps of: a) depositing a first layer of powder onto a work area constituted by a plate; b) compacting said first layer; c) solidifying a first area of the layer compacted in step b) using a laser beam, said area corresponding to a section of the bottom of the finished object (O); and d) repeating steps a) through c) until the object is obtained. The method includes at least one additional step of: e) before step c), producing, by solidifying a powder using the laser beam, a member (12) for absorbing deformations to be arranged between the work area (1) and an area to be part of an area corresponding to a portion of a bottom (9) of the finished object (O) manufactured in step c). The absorption member produced in step e) includes a deformable substrate (12) consisting of a plurality of blades capable of connecting a surface (2) of the plate (1) to the first area constituting a surface (9) of a bottom of the object (0). |
