We know that a RepRap can (mostly) reproduce itself, but have you ever actually seen this happen? Pictures or it didn’t happen! Now we can see this process when Gavilan Steinman of onshoulders.tv takes a Darwin RepRap printer to produce parts to build a new RepRap Mendel 3D printer. Then (thankfully in high-speed motion, up to 25,000x normal speed) Gavin assembles the new Mendel 3D printer before our eyes.
