Method for manufacturing an object by solidifying powder using a laser beam with the insertion of a member for absorbing deformations

Method for manufacturing an object (0) by solidifying powder (3) using a laser beam (4) including at least steps consisting of:

• a) depositing a first layer (6) of powder (3) onto a work area constituted by a plate (1),
• b) compacting said first layer (6),
• c) solidifying a first area (7) of the layer compacted in step b) using a laser beam, said area corresponding to a section of the bottom wall (9) of the finished object (O),
• d) repeating steps a) to c) until the object (O) is obtained,
• e) before step c), producing, by solidifying a powder (3) using the laser beam (4), a member (12) for absorbing deformations arranged between the work area (1) and an area to be part of an area (7) corresponding to a section of the bottom wall (9) of the finished object (O) produced in step c), wherein the absorbing member produced in step e) comprises a deformable substrate (12) consisting of a plurality of strips (120) suitable for connecting a surface (2) of the plate (1) to the first area (7) constituting a surface (9) of the bottom wall of the object (O).
