Manufacturing a propeller with investment casting consumes times due to the wax pattern molding process. Replacing the pattern material to polylactic acid (PLA) would improve process efficiency. This material can be printed with a 3D printer with results that are close to the size of the final product. This allows to cut the wax pattern molding process. This research aimed to make a propeller u…
