In the context of present-day industries needs, such as improvement of resin-bonded grinding wheels, the authors propose a promising method for fabricating the resin-bonded grinding wheels (the authors named "Resin-Piled wheel : RP wheel") by stereolithography. In this proposal, the photohardenable resin/grain mixture is used to fabricate the resin-bonded grinding wheel. This paper describes the results of fundamental study. First, we revealed the optimum stereolithography conditions by curing tests. Subsequently, we developed the special experimental apparatuses (SLA and RCA), and carried out the fabrication of the 1A1-type wheels and the stick type wheels using these SLA and RCA. Furthemore, the grinding tests were performed. The main superiorities of RP wheel compared to the commercial wheels are as follows; (1) drastically decreasing of fabrication time within 10 min, (2) few coagulation of abrasive grains, (3) lower wheel wear in grinding with smaller surface roughness.
