Additive manufacturing systems and methods including rotating build platform

A method of fabricating a component using an additive manufacturing system, said method comprising:

• rotating a build platform about a rotation axis at a first speed using a first actuator assembly, the rotation axis extending through a center of the build platform;
• rotating a shaft about the rotation axis at a second speed different from the first speed using a second actuator assembly, wherein the shaft extends along the rotation axis and is coupled to the build platform to translate the build platform along the rotation axis upon rotation of the shaft;
• depositing a particulate onto the build platform;
• consolidating at least a portion of the particulate using a consolidation device;
• and
• adjusting at least one of the first speed and the second speed based on a characteristic of the component and an operating parameter of the consolidation device.

An additive manufacturing system comprising:

• a build platform configured to receive a particulate;
• a particulate dispenser configured to deposit the particulate onto a central region of said build platform;
• a first actuator assembly configured to rotate said build platform about a rotation axis, the rotation axis extending through a center of said build platform;
• a second actuator assembly configured to translate said build platform along the rotation axis;
• at least one recoater blade positioned adjacent said build platform, wherein said at least one recoater blade is fixed in position during rotation of said build platform and is configured to contact the particulate deposited on the central region of said build platform and to distribute the particulate across said build platform;
• and
• at least one consolidation device configured to consolidate at least a portion of the particulate to form a component as said at least one recoater blade distributes the particulate.
