| Research Abstract |
We developed the micro cutting instrument and micro molding instrument which fuse the stereo-lithography techniques and the molding ones. The cutting instrument is same as the AFM(Atomic Force Microscope) structure. The diamond tip mounted on a top of the AFM cantilever contacts the sample surface under constant normal load and the sample is moved along X and Y direction to cut the surface. Then, the deflections of the cantilever were measured by laser displacement meter to keep constant normal load. The movement of Z direction and X-Y direction are controlled by PZT stage and pulse motor stage, respectively. The each instruments are controlled by the personal computer and connect the GP-IB or RS232C interface together. Therefore the shape of parts which can be created in this system are 2.5 dimension.
The micro molding instrument can mold the micro parts which made of photopolymerizable resin. The instrument consists primarily of 1) die sets, 2) core and cavity and 3) UV(Ultraviolet Rays) irradiation instrument. The minimum shape of micro parts which can be made is approximately ten μm wide and one μm depth. The maximum shape is approximately ten mm width and a few ten μm depth. It is recognized that the transfer between molded part and mold shape is very good. Also the ejection property depends on the amount of resin and lubricant on the cavity. So the technical problems of mass production of micro parts make clear in this study.
