The Carpenter Cobalt-Chromium-Molybdenum - Middle Carbon (CCM-MC) alloy powder is being evaluated as a viable material for component fabrication via Binder-Jet Printing (BJP) additive manufacturing. Results from sintering experiments where obtained at temperatures of 1285°C, 1300°C and 1325°C. Initial sintering response was measured through assessment of final densities. Densities of 80 to 100 percent of theoretical were obtained with some evidence of liquid phase sintering. Binder saturation levels seem to have an effect not only on printing dimensional anisotropy, but also on optimum sintering temperatures and resultant chemistry. The chemistry, microstructures and mechanical properties of BJP CCM-MC are compared to those of laser powder bed fusion (LPBF) additive manufacturing.
