Increasing porosity and generating expected internal structure for metal-bonded grinding wheel are the critical enabling technologies for high performance grinding wheel fabrication. Conventional hot pressing sintering (HPS) fabrication process has little capability in active formation of pore structure. In this paper, metal 3D printing technology is applied to fabricate the composite used for metal-bonded diamond grinding wheel. Through the measurement of morphological properties, mechanical properties and forming limits, the formability and performance of 3D-printed composite are evaluated. To predict the mechanical performance and understand the failure behavior, the representative volume element (RVE) model is developed for the 3D-printed metal matrix composite. And final grinding experiment indicates that 1) The 3D printing technology for composite and complicated internal structure exhibits promising potential for high performance grinding wheel fabrication with inter-connected lubrication channel and sufficient mechanical strength; 2) The 3D-printed porous wheel demonstrates sufficient durability in grinding process and superior performance in grinding capability.
