Systems and methods for non-continuous deposition of a component

A method of manufacturing using an additive manufacturing process includes providing a deposition system, the deposition system configured to provide a plurality of cells to form a blank of a part, depositing a first layer of the blank, the first layer comprising a first deposited cell, a second deposited cell spaced apart from the first deposited cell, and a third deposited cell spaced apart from the first deposited cell and the second deposited cell, and depositing a second layer of the part on the first layer, the second layer comprising a fourth deposited cell, a fifth deposited cell spaced apart from the fourth deposited cell, and a sixth deposited cell spaced apart from the fourth deposited cell and the fifth deposited cell. Each of the first layer and the second layer are formed using non-continuous deposition to form the blank.

Dynamic detection of layer thickness for an additive manufacturing process
11826829 · 2023-11-28 · ·

A method for dynamically controlling layer thickness during an additive manufacturing process of building a block including an object with layers of powder material, detecting a height of the block after each layer is compacted, determining a delta between the detected height and a height in a computer model defining slices of the block and compensating for the determined delta in subsequent cycles. A cycle in the additive manufacturing process includes selectively printing a layer pattern, spreading a powder layer over the layer pattern with a spreader and compacting the powder layer with the layer pattern.
