Abstract
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.
