Creating a Terminator Skull Using the Lost PLA Casting Process #SciFiSunday

On AndysMachines, Andy creates an amazing Terminator skull starting off by fabricating most of the parts using lost PLA casting. This is when you 3D print models of parts, create a mold around them, and then heat up the mold to melt away the PLA plastic inside so that it’s ready for a metal pour (in this cast aluminum).

As Andy points out, it’s not a tremendously precise process and there was a lot of post-processing, but it definitely saves time over having to hammer sheet stock and machine all of the skull pieces.
