Powder-based additive manufacturing method for parts for tire molds, in particular lining blades and related reinforcing elements

摘要

An additive manufacturing method of at least one part by powder sintering or powder melting using at least one energy beam, comprising: a) depositing and selectively melting the stacked powder layers; At least one local area extending in a direction substantially parallel to the stacking direction of the layers, having a split tube shape surrounding each of the side end faces of the part and facing each of the front faces adjacent to the end face of the part A manufacturing step for producing at least one intermediate element comprising a structural reinforcement element; and b) a separation step for separating the part and the local reinforcement element.
