[sudo-discuss] Lost wax casting [was Re: robot arm]

On the topic of lost wax casting... If someone knows a jeweler who has the equipment to 3D print in wax and then cast in metal, let me know! This is the process Shapeways uses for their precious metal 3D prints, but they charge an arm and a leg for them. I would love to be able to produce 3D printed jewelry at the same rates as these guys have figured out: https://www.kickstarter.com/projects/fireandbone/fire-and-bone-tiny-digital… Also - you can totally do lost "wax" casting using 3D printed PLA instead of wax! Lost PLA Casting from 3D Prints <http://3dtopo.com/lostPLA/> Or you can even use low-melt alloys to cast directly into 3D printed ABS molds: Metal Casting with Your 3D Printer <http://makezine.com/projects/guide-to-3d-printing-2014/metal-casting-with-your-3d-printer/> Patrik PS: The "Field's metal" mentioned in the last link is a non-toxic alloy that melts at 144°F, and is named after its inventor, local South Bay mad scientist Simon Quellen Field.
