  2. Current Plans • Use Compression Molding for the interference screw • Design mold of screw in SolidWorks • Machine mold out of Teflon • Matthew Harmon from UCHC is a good source for molds • Once mold is complete, use molding device at UCHC to fabricate screw from novel material

  3. Current Plans • Use 3-D printing for hamstring tendon casing • Tom Mealy from ME department is a good source for 3-D printing • Search for possibly ways of fabricating the tendon casing out of novel material

  4. Progress with Compression Molding • Dr. Kumbar’s Mystery Device • Looks similar to the device shown to the right • Contains a heating plate with temperature gauge • Contains a lever with pressure gauge • Can be used to manually compress any type of mold http://www.compositesworld.com/products/retrofit-refurbish-upgrade-kits-for-phi-bench-presses

  5. Progress with Creating Mold • Successfully “shut off” surfaces • Identified “Pull Direction” • Created a “Parting Line” • Need to create “Parting Surface,” but have been unsuccessful due to geometric conditions

  6. Progress with 3-D Printing • Ben is in touch with Tom Mealy • Trying to set up a good time to print our hamstring tendon casing

  7. Future Work • Finish creating mold in SolidWorks • If problems persists, contact Matthew Harmon • Visit UCHC on 2 / 22 / 13 • Set up date for 3-D printing
