Additive Manufacturing of Shape Memory Polymers: Effects of Print Orientation and Infill Percentage on Mechanical and Shape Memory Recovery Properties
DownloadFall 2017
Material Extrusion Additive Manufacturing (MEAM), also known as Fused Deposition Modeling (FDM), is a manufacturing technique in which three-dimensional objects are built. These objects are built by repeatedly extruding thin layers of molten materials through a nozzle in different paths and...

Geometric Tolerance Quantification and Prediction Framework for Additive Manufacturing Processes
DownloadFall 2021
Additive Manufacturing (AM) is an advanced manufacturing technology used to manufacture custom and geometrically complex parts using a layer-by-layer material addition process. Variations in the AM process lead to ‘deviations’ in the manufactured part, resulting in geometric non-conformance. To...
