Real solution.

“The tool we developed combines the two existing tools into a single unit,” says design engineer Richard Franks. “As the surgeon squeezes two handle pieces together, the ratchet tightens the screws.” The engineers produced a working polycarbonate ratchet strong enough to withstand testing on stainless steel set-screws and durable enough to survive an autoclave. In addition, says senior engineering manager Troy McDonald, “Surgeons are really rough on these prototypes while trying them out, so we have got to have tough material. FDM gave us the strength and durability we needed.”
“The models that we were outsourcing were not as accurate as what we are getting from our Stratasys printers.”
