    摘要: The disclosure relates to a selective laser sintering method of manufacturing a tread molding element, said tread molding element including at least a fine lamella adapted to mold a shallow ripe in a tire tread, the fine lamella having a length (L2). The fine lamella is sintered in a plurality of portions (p2) at different layers (N), in each layer (N) the laser beam sinters the portion (p2) of the fine lamella in only one passage in the length (L2) of the fine lamella without round-trip passage of the laser beam, the direction (D1) of this passage being the same at the different layers (N) for building the different portions (p2) of the fine lamella. The thickness (w) of the fine lamella is smaller than 0.2 mm, and the height (h) of the fine lamella is smaller than or equal to 2 mm.

    摘要: The invention concerns a part obtained by selective melting of a powder on a support plate (2), said part (1) comprising a main element (3) and rigid secondary elements (5a, 5b, 5c), said secondary elements (5a, 5b, 5c) supporting the main element (3) between a lower surface (7) of said main element and the support plate (2). The secondary elements (5a, 5b, 5c) are intended to be detached from the main element (3). The lower surface (7) of the main element thus comprises a first surface portion (9) and at least one second surface portion (11), and the first surface portion (9) forms, with the support plate (2), an angle α1 less than a predefined value, and the second surface portion (11) forms, with said support place (2), an angle α2 greater than or equal to said predetermined value. The first surface portion (9) is then completely supported by the secondary elements (5a) and the second surface portion (11) is partially supported by the secondary elements (5b). The predetermined value is between 20° and 30°.

    摘要: The invention relates to a moulding element for a mould for a tyre, produced from a metal powder melted layer by layer. The moulding element (1) comprises a body (3), said body comprising a first surface (5) for moulding all or part of a tread surface of the tyre and a second surface (7) which opposes the first surface and is to be brought into contact with another part of the mould, the thickness (E) of the body of the moulding element being between 1 and 6 millimetres. The moulding element comprises at least one cavity (9) which opens out onto the second surface of said body. The moulding element also comprises a plate (11) arranged across the cavity and forming a single component with the body of the moulding element, said plate being on the same level as the first surface (5) of the body. The plate (11) comprises at least one hole (13) allowing air to pass between the first surface (5) of the moulding element and the second surface (7) thereof.
