ADDITIVE MANUFACTURING SYSTEMS AND METHODS INCLUDING ROTATING BUILD PLATFORM

Abstract:

Methods and systems for fabricating a component by consolidating a particulate include a build platform configured to receive the particulate, a particulate dispenser configured to deposit the particulate onto the build platform, and a consolidation device configured to consolidate at least a portion of the particulate to form a component. The methods and systems also include a first actuator assembly configured to induce rotation of the build platform about a rotation axis at a first speed. The rotation axis extends through a center of the build platform. The methods and systems further include a second actuator assembly including an actuator and a shaft extending along the rotation axis. The actuator is configured to cause rotation of the shaft about the rotation axis at a second speed different from the first speed. The shaft is coupled to the build platform and configured to induce linear movement of the build platform along the rotation axis upon rotation of the shaft.
