X-Winder: Carbon Fiber Wrapping

ScreenShot035

One of our readers just sent us a tip about this interesting kickstarter project. [Turner Hunt] is bringing carbon fiber manufacture into the hands of makers — at considerable cost savings!

So how does it work? The machine wraps the filament around the workpiece, not unlike a CNC lathe in reverse. Actually it’s kind of a new breed of 3D printer! As the machine feeds the filament, it dips it through a bath of epoxy resin before being wrapped around the workpiece. A finishing step wraps heat shrink tape around the finished project using a heat gun, which then provides a glossy surface finish very similar to commercial carbon fiber products.

By purchasing carbon fiber filament and epoxy resin and using this machine, you can create structural carbon fiber tubes for about 80% less than they would cost commercially. The system comes with its own software that controls the machine via g-code, and you can also specify different wrapping patterns for different applications. While tube-shapes work best, you can also wrap other shapes including flat bars, wing skins, turbine blades and more — anything that is wrappable and under 6″ in total diameter. Is anyone else thinking about custom wrapped quadcopter frames?
