RISEffect of Thermal Deformation on Part Errors in Metal Powder Based Additive Manufacturing Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In metal additive manufacturing (AM) processes, parts are manufactured in layers by sintering or melting metal or metal alloy powder under the effect of a powerful laser or an electron beam. As the laser/electron beam scans ...
Increasing Part Accuracy in Additive Manufacturing Processes Using a k d Tree Based Clustered Adaptive Layering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Additive manufacturing (AM) is widely used in aerospace, automobile, and medical industries for building highly accurate parts using a layer by layer approach. The stereolithography (STL) file is the standard file format ...
Adaptive Slicing in Additive Manufacturing Process Using a Modified Boundary Octree Data Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In additive manufacturing (AM) processes, the layerbylayer fabrication leads to a staircase error resulting in dimensional inaccuracies in the part surface. Using thinner slices reduces the staircase error and improves ...
Error Minimization in Layered Manufacturing Parts by Stereolithography File Modification Using a Vertex Translation Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Layered manufacturing (LM) machines use stereolithography (STL) files to build parts by creating continuous slices on top of each other. An STL file approximates the surface of a part with planar triangles. This results ...
