Noyau de fonderie pour aube de turbine de moteur d'avion fabriqué par stéréolithographie
Precision casting core for a turbine vane for a plane engine, manufactured by stereolithography. This core is positioned in a mould, also made from a ceramic material. This means it is left inside after demoulding of the metal part, which is cast at a high temperature (around 1500°C). The core is then removed by chemical etching, leaving a cavity for cooling the turbine vane, in this application.
