Study on the Joining of 2D Microstructure during the Fabrication of 3D Micro-Mold
Bin Xu,Xiao-yu Wu,Jian-guo Lei,Feng Luo,Chen-lin Du,Shuang-chen Ruan,Zhen-long Wang 한국정밀공학회 2014 International Journal of Precision Engineering and Vol. No.
The 3D micro-mold which is fabricated by the femtosecond laser cutting and micro electric resistance slip welding is formed throughthe lamination of multilayer 2D microstructures. By using this technology, the 3D micro-mold with a high depth-width ratio can bemanufactured. In order to improve the laminated precision and joining strength of each layer of 2D microstructure, this researchapplied layer-by-layer micro electric resistance slip welding to weld each layer of 2D microstructure. Firstly, the proper technicalparameters were obtained through the experiments of layer-by-layer micro electric resistance slip welding. Secondly, through thelayer-by-layer micro electric resistance slip welding, multilayer 2D microstructures were weld together and a 3D micro-mold wasformed. Moreover, the anti-shear stress test of 3D micro-mold was done. In the layer-by-layer slip welding process, electrode couldproduce some losses and the losses could deposit on the surface of micro-mold. This research also studied the deposition effect ofthe electrode. Finally, based on the above studies, the micro square-hole array and the micro-gear cavity were fabricated by joiningmultilayer 2D microstructure.
