| Abstract Scope |
The Bound Metal Deposition (BMD) process extrudes a bound metal mixture to a green part and then finishes with a sintering cycle to produce the final component. The process involves several steps and results in a final component that is approximately 15-20% smaller than the original green part. This process represents a way to prototype metal parts using Additive Manufacturing without the need for special environmental controls required for powder-based processes. However, the multiple processes involved (printing, debinding, and sintering) can result in dimensional variability in different directions in the part. This study measured the effects of wall thickness on the dimensions, microstructure, and hardness at different stages of the process and in different orientations to develop design rules and gain an understanding of the dimensional sintering scaling factors required to produce parts to match the input design CAD. |
