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.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
