Hi there I live in San Francisco and I am trying to understand a status of the Metallica RepRap 3D Printer. Has anyone been able to build a prototype of Metallica RepRap with Electron guns using EBM.I see Arcam has some EBM 3D printers. Are these essentially the same as described in the Metallica RepRap? If funding is the only issue, then I think I can help to raise the funds for a project andby mmajumdar - MetalicaRap
