Today WASP has unveiled a new LDM Extruder which they are selling as an add-on to other 3D printers. They say it can be hooked up to virtually any 3d printers on the market, and it prints with precision very close to what is seen with typical plastic extrusion systems. The results of some of their prints are really incredible. they can even 3D print ceramic rings. Read and see more on this at: http://3dprint.com/82963/ldm-wasp-extruder-ceramics/
