In the context of current industrial needs, such as the 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 some results of fundamental study. First, we revealed the optimum stereolithography conditions by curing tests. Subsequently, we developed the special experimental stereolithography apparatus (SLA), and carried out the fabrication of the 1A1-type wheels and the mounted wheels using this SLA. Furthermore, the grinding tests were performed. The main superiorities of the 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) better surface roughness with lower wheel wear.
