Binder jetting 3D printed cemented carbide: Mechanical and wear properties of medium and coarse grades

Selective laser melting (SLM) is the most widely used additive manufacturing (AM) technology to 3D print metals. Several researchers have tried, unsuccessfully, to produce cemented carbide by SLM. Binder jetting 3D printing (BJT) and micro-extrusion-based methods are 2 AM technologies that have been...

Zusammenfassung:Selective laser melting (SLM) is the most widely used additive manufacturing (AM) technology to 3D print metals. Several researchers have tried, unsuccessfully, to produce cemented carbide by SLM. Binder jetting 3D printing (BJT) and micro-extrusion-based methods are 2 AM technologies that have been successfully applied to the printing and sintering of cemented carbide. We report the development of medium and coarse WC-Co powders for BJT with Co contents of 10%, 12%, and 17%. The free flowable (Carney flow
