Title: AUTOMATIC SPREADER BAR BLADE MATERIAL POSITIONING FOR ADDITIVE MANUFACTURING
Abstract:
In one example, an additive manufacturing system. The system includes a blade spanning at least a portion of a build bed along a y axis and movable across the build bed along an x axis orthogonal to the y axis. The blade includes blade material to spread build material on the build bed. The system further includes a blade positioning mechanism coupled to the blade to position a different portion of the blade material adjacent a given y position of the build bed.
