  • Electron beam melting additive manufacturing machine with dynamic energy adjustment
    Patent number: 11491575
    Abstract: An electron beam melting machine and a method of operation are provided which maintains constant energy absorption within a build layer by adjusting an incident energy level to compensate for energy not absorbed by the additive powder. This unabsorbed energy is detected in the form of electron emissions, which include secondary electrons, backscattered electrons, and/or electrons which are transmitted through the build platform.
