Multi-material Additive for Sinter-Based Materials

ABSTRACT: Multi-material additive manufacturing (MMAM) has been demonstrated in varying capacities, such as multi-color polymer extrusion, inkjet deposition of multiple photopolymers, or large-scale metal additive manufacturing (AM) with multiple alloys. A new concept for MMAM is the combination of sinterable materials such as powdered ceramics and metals, which are shaped via indirect AM methods and consolidated via sintering or other means. This presentation reviews current progress in MMAM for sinterable materials in shaping and consolidation techniques, identifies key application opportunities for sintered MMAM artifacts, and outlines a path forward for consolidation of multiple, sinterable materials combined in complex structures via AM.
