日本名古屋大学的生田幸士教授等新近开发出简单的微机械制作方法,可以制作直径几十微米的齿轮、车轮、链条等部件。用聚焦成非常细的激光束照射光硬化树脂,以1μm以下的精度形成部件。仅需3～5min时间即可根据要求制成立体形状部件。目前研制的是装在粗10μm、长100μm旋转轴上的直径47μm的齿轮。该齿轮有8个齿, Japan’s Nagoya University, Professor Shi Tianshizhi newly developed a simple micro-mechanical production methods, you can make the diameter of tens of microns of gears, wheels, chains and other components. The light-cured resin was irradiated with a very thin laser beam focused to form a member with an accuracy of 1 μm or less. Only 3 ~ 5min time can be made according to the requirements of three-dimensional shape parts. Currently developed is mounted on the coarse 10μm, length of 100μm axis of rotation 47μm diameter gear. The gear has eight teeth,
