Using Collaborative Robots to Assist with Travel Path Development for Material Deposition Based Additive Manufacturing Processes
Abstract. Additive manufacturing (AM), or 3D printing, is a manufacturing solution where a CAD model is sliced into layers, and each layer manufactured using 2D travel path solutions. The final component is the resultant of a set of stacked layers. Typically the outer boundary contour are created first (either by depositing material or applying a heat source onto deposited material), and then a raster scan zig-zag pattern is used to fill the interior of the layer. For thin walled components, simple contours may be stacked to create a 3D component. The AM fabrication strategy is advantageous compared to the thin wall problem set, as there is significantly less material usage. For the hexagonal shape, the deposited material is approximately 12.5% of a solid hexagon with the same perimeter contour or 8% of a cubic stock block (a bounded cube). Consequently, the material deposition AM family of solutions introduces significant materials savings opportunities, especially for expensive, exotic metal alloys (i.e. superalloys, titanium, etc.).
