Need nylon parts fast? Try vacuum casting them using a new rapid prototyping process developed by MCP Systems and offered in North America by Vantico A&T US Inc. (www.vantico.com). Thanks to a new nylon program module, MCP's vacuum casting machines can produce complex nylon parts with walls as thin 0.02 inch—and do so in as little as six minutes. MCP also introduced new nylon 6 formulations for the new process. Properties include flexural modulii from 108,750 to 137,750 psi, tensile strengths from 4,640 to 6,090 psi, and heat deflection temperatures from 169 to 269F (at 66 psi).
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
