Abstract
A part obtained by selective melting of a powder on a support plate having a main element and rigid secondary elements arranged between the main element and the support plate, and adapted to be detached from the main element. All or part of the secondary elements comprises a body of thickness E and a head of width L greater than the thickness E of this body, the body connected to the support plate and the head connected to main element. All or part of the secondary elements includes a region of connection between the head and the body. The head of the secondary element extends over at most half the height H of this element.
