Abstract Scope |
A potential issue that arises during the post-processing of binder-jet printed samples is incomplete binder removal, leading to carbon pick-up by the material during sintering. In this project, samples of wrought stainless steel with different carbon concentrations were heat treated to produce different extents of carbide precipitation. These samples were metallographically polished and etched to generate a set of images that will be used to test a computer-vision approach to classifying the extent of carbide precipitation, to be applied to sintered parts. In addition, the thermal response of cubes of different sizes will be measured during debinding treatment and the resulting thermal history will be used to fit the thermal diffusivity – since the heating rate can affect the extent of binder removal. |
