Hi Viktor!, I think you mean about the focus spot size?. When the focus size is big, you will have a gradient and the heat is not applied efficiently in the spot. In the case of electron beam, you can control the focus size. Regards!by chucrutcito - MetalicaRap
Hi Viktor!, I dont have experience welding Kovar and Inconell yet. Maybe is more difficult. I can test later. I have welded stainless steel with the electron beam and I find it relatively simple to position the electron beam in welding applications. I have uploaded this video for showing the electron gun testing: I can upload more videos later. You can assign a trajectory to the beam (spiral, sby chucrutcito - MetalicaRap
Many thanks Viktor!, The price estimation is around 6.000USD for this 3D Metal Printer if you make it yourself, using the final design. The research & development is more expensive. If you support me with the development, i can continue working fulltime in this project and publish the designs, schematics, tests, etc. The advantage of using an electron beam, is the faster XY speed using coilsby chucrutcito - MetalicaRap
Hello!, My name is Agustin. I'm from Chile. I have been reading and following MetalicaRap for many years, and I would like to share with you my creation. I'm making a 3D Metal Printer using an electron beam. Is a very expensive project, and I have worked many years on it. Now I'm opening the project to the community inside a crowdfunding model. I'm going to share the design, tests, updates, so Iby chucrutcito - MetalicaRap
