| Abstract Scope |
Binder jet additive manufacturing (AM) is a growing field that presents large upsides in the production of metal parts. By utilizing powder metallurgy and the binder jet AM process, it is possible to create near net shaped parts, and binder jet has been shown to maintain higher productivity and lower operation costs than other metal AM methods. H13 is a tool steel that is utilized to create many hot working tools for manufacturing. Traditionally, binder jetting H13 parts that meet chemical specifications has been challenging due to the addition of carbon by the binder. One way to combat this challenge is to create parts utilizing minimal binder, but the low content of binder often leads to parts that break before they can be sintered. Thus, careful balancing between binder content and carbon pickup must be made. In this study, Oak Ridge National Laboratory researched processing parameters to minimize carbon pickup and to produce viable preforms for handling. |
