Abstract

Various embodiments include methods and related systems for laser-assisted casting. Some embodiments include a method including: performing P2 laser ablation to a preliminary wax casting model 6 to form a modified wax model 8 including at least one additional feature 10 absent from the wax casting substrate; coating P5 the modified wax model 8 to form a mold shape around the modified wax model 8; and removing P6 the modified wax model 8 to leave a casting mold 24 including the at least one additional feature 10.
