Vibration isolation device for an additive manufacturing machine

An additive manufacturing machine (900) includes a build unit (904) that is supported by an overhead gantry (918). The build unit (904) includes a powder dispenser (906) including a vibration mechanism (922) and a scan unit (908) including a powder fusing device (910) for fusing or binding portions of a layer of additive powder. A vibration isolation device (932), such as a passive rubber damper (940) or an active vibration canceling mechanism (960), is positioned between the powder dispenser (906) and the scan unit (908) to prevent vibrations in the powder dispenser (906) from causing operational issues with the scan unit (908) and inaccuracies in the additive manufacturing process.

Systems and methods for additive manufacturing

An additive manufacturing system is provided. The additive manufacturing system includes a build platform and at least one workstation. The build platform defines a continuous workflow path and is configured to rotate about a build platform axis. The workstation is spaced apart from the build platform along the third direction and at least one of the build platform and the workstation is configured to move along the third direction. The workstation includes at least one particle delivery device, at least one recoating device, and at least one consolidation device. The particle delivery device is configured to deposit particles on the build platform. The recoating device is configured to distribute the deposited particles to form a build layer on the build platform. The consolidation device is configured to consolidate at least a portion of the build layer.

Electron beam melting additive manufacturing machine with dynamic energy adjustment

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.
