3D Printing Integrated Fabrication of CathodeHeater Assembly

摘要

This paper reports on a new type of cathode-heater assembly and uses the selective laser melting (SLM) technology in 3D printing to achieve an integrated fabrication process. A thermal resistance of about $0.4Omega$ reached after the excess heater sub-support columns are fused with a high energy laser. After applying a heating power of 21.6 W, the heater generated by the SLM reached a temperature of 1250 °C.
