Abstract
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 sipe in a tire tread, the fine lamella having a length (L). The fine lamella is sintered in a plurality of portions (p) at different layers (N), in each layer (N) the laser beam sinters the portion (p) of the fine lamella in only one passage in the length (L) of the fine lamella without round-trip passage of the laser beam, the direction (D) of this passage being the same at the different layers (N) for building the different portions (p) 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.
