This presentation will review a new Additive Manufacturing technique for metals to fully support a part during processing, while making it simple to remove the support structures once complete. Many complex shapes are candidates for additive manufacturing. Such shapes often require structural supports for printing and post processing. While the removal of such supports is fairly trivial for AM plastics, the removal of metallic supports represents a large cost and barrier to adoption to additive manufacturing of metals.
We will explain the process which enables a fully dense metallic part to be lifted off of its support structure after post-processing. This presentation will detail the technique used for supporting metal parts and will address impacts of such a technique on the parts including material efficiency, dimensional accuracy, and material properties.
