<p>The invention concerns a part obtained by selective melting of a powder on a support plate (3), said part (1) comprising a main element (5) and rigid secondary elements (7), said secondary elements being disposed between the main element (5) and the support plate (3), the secondary elements being intended to be detached from the main element (5). All or some of the secondary elements (7) comprise a body (9) of thickness E and a head (11) of width L greater than thickness E of said body (9), the body (9) being linked to the support plate (3) and the head (11) being linked to the main element (5). All or part of the secondary elements (11) comprise a connection area (13) between the head (11) and the body (9). The head (11) of the secondary element extends, at most, over half of height H of this element (7).</p> |
