It is important to know mechanical properties of micro structures fabricated as a micro machine component by micro-stereolithography(μSL). In the previous study, we reported that elastic modulus of a micro-cantilever fabricated by μSL is controllable by irradiation laser power and postcure processing time. In this study, micro-cantilevers are formed by changing lamination pitch (10μm to 25μm) and lamination orientation. Then, the relation between the load and the deflection of the cantilever is evaluated. Experimental results show that the elastic modulus of the cantilever decreases with the increase of the lamination pitch, also it depends on lamination orientation.
