| Abstract Scope |
Binder jet additive manufacturing (BJAM) can produce a wide range of geometries and unique features with a tolerance range comparable to most sinter-based processes. As such, BJAM of WC-Co has been demonstrated for use in many commercial applications, such as wear components and metal cutting tools. The development of a new product, and replication of a first article to small lot production to full scale manufacturing, has several challenges that must be overcome in achieving the necessary process capability. In addition, BJAM of WC-Co presents additional challenges due its high density (nearly 2x stainless steel) and the necessity of liquid phase sintering to achieve the intended properties for its applications. This presentation will discuss important considerations for minimizing process variation in the printing and sintering processes when scaling a BJAM component from prototypes to serial production. Recommendations for critical to quality metrics and appropriate data analysis will be discussed. |
