capabilities of Geomagic Studio were thenused to repair intersections, fill holes, and refine floating data and edges. The Select byCurvature command was employed to relax the structure while retaining detail. A NURBS (Non-Uniform Rational B-Spline) surface was created to finalize the mesh structure and export it as an.stl file. Once the 3D mesh is generated, the number of triangles comprising the mesh must bereduced in order to lower computing lag. MeshLab software was utilized to reduce the number oftriangles below 8,000. Autodesk Meshmixer allows for simple, yet detailed modification of .stlfiles through direct editing of a mesh geometry, a feature that is not available in SolidWorks.SolidWorks requires a subtraction command to generate the scanned

It is important to note that the A and B coefficients in the up and down positionsare the same. This means that system identification in the stable, downward position can be usedto experimentally determine the values

conducted trade studies. In the trade studies theylooked at different types of actuators, clamp actuators, injection methods, machine orientation, and machineoperation. Within each section they set up a table to compare the options available and set up a scoring system.By using a scoring system, it helped to identify which option would be the best for the application. The scoringwas done on a scale of 1- 4 with 1 being the least favorable and 4 being the most favorable, specifically accordingto their application. A copy of the trade study can be seen in Appendix B. In conjunction with the trade study,they looked to the survey results to see which options the trade studies yielded as the best fit, with whatequipment the educators had access to. For
