Additive manufacturing, also known as 3D printing, provides new opportunities in the production of highly complex, mass-customized structures. Binder jetting is a fast, low-cost manufacturing method for creating stress-free structures with complex internal and external geometries. We use binder jetting (ExOne M-Flex) to produce metal frameworks for removable partial dentures. An existing framework is scanned using micro-computed tomography (μCT) and printed. Sintering results in > 99% density with controlled shrinkage. Microhardness of the densified framework is ~285 HV0.1. The printed and then sintered part fits well in the cast model indicating that the μCT model and the afterward sintering condition are properly chosen. These results demonstrate that binder jetting can be used to produce mechanically sound thin walled complex-shaped overhanging structures as shown here on a denture metal framework model.
