Size, geometry and cost constraints posed problems for design engineers at Gyrus Medical in Minneapolis MN, when designing the jaws for a single-use bipolar open-forceps surgical instrument that uses RF energy. Tight tolerances over the length of the part (about 4.5 inches) were also an issue. The instrument will only perform properly if the surfaces remain parallel. Gyrus looked at casting and machining before choosing metal-injection molding. "Any time we need that kind of accuracy, we're going to look for a MIM-molded part," says Craig Stowell, director of engineering for Gyrus Medical. Phillips Plastics developed custom ceramic fixtures to support the parts to eliminate sagging during the production process. The parts then went through a calibration process to meet final print specifications.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
