Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and in particular relates to a three-degree-of-freedom precision operation device and an excitation method for forming microstructures on the surface. Background technique [0002] Rapid prototyping technology is a "growth" manufacturing method based on the idea of ​​"discrete / stacking". It usually integrates computer-aided design and computer-aided manufacturing with the help of modern means such as computers, lasers, micro-injection, precision transmission and numerical control. The 3D data model designed on the above can directly manufacture products or samples in a very short time. Rapid prototyping technology is a new manufacturing concept, that is, additive manufacturing. Compared with the traditional subtractive material removal method, the additive additive manufacturing method has obvious advantages of high processing accuracy, high material utilization rate and the ability to...
