Jonathan Holman is currently a student at the University of Pittsburgh at Johnstown, majoring in Mechanical Engineering. He founded a club devoted to researching and learning about the Additive Manufacturing process through hands-on projects at UPJ. He spends lots of time working with various FDM (Fused Deposition Modeling) 3D printers. Ranging from professional systems, to RepRap style kit printers, he works on all of them. When he isn't working on 3D printers, Jonathan is learning more about them through research projects, and experiments, ranging from testing materials for strength, to experimenting with new ways to implement design and process techniques for Additive Manufacturing. He is currently engaged in numerous projects in the field of Additive Manufacturing covering a range of topics.

Analyzing the Composite 3D Printer Frame for Rigidity Abstract Additive Manufacturing offers a wide variety of options when it comes to the construction of a part. Different infill patterns, infill densities, varying shell thickness, and different materials all have different effects on the final strength of a functional 3D printed part. This paper studies the benefits of using a fused deposition modeling (FDM) process to print a part completely hollow and fill the completed hollow shell with epoxy resin to create a solid component. FDM is also known as fused filament fabrication (FFF). Often times, large functional FDM parts can take quite a long time to complete printing due to high strength setting requirements. Hollow parts can print much faster than parts with infill, then be filled with an epoxy resin to create a solid part in much less time. When cured, the resin filled components will produce a stronger and more rigid finished product than a printing the part with comparable print settings. To illustrate this, a 3D printer frame was designed, analyzed with an FEM simulation and fabricated.
