Current PlansUse Compression Molding for the

interference screwDesign mold of screw in

SolidWorksMachine 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

Current PlansUse 3-D printing for hamstring

tendon casing◦Tom Mealy from ME department is a

good source for 3-D printingSearch for possibly ways of

fabricating the tendon casing out of novel material

Progress with Compression MoldingDr. 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

Progress with Creating MoldSuccessfully “shut

off” surfaces Identified “Pull

Direction”Created a “Parting

Line” Need to create

“Parting Surface,” but have been unsuccessful due to geometric conditions

Progress with 3-D PrintingBen is in touch with Tom Mealy

◦Trying to set up a good time to print our hamstring tendon casing

Future WorkFinish creating mold in
