Most lithography-based micro-forming technology has the limitations in materials selection, forming efficiency and the complexity of micro-parts etc. It is urgent to develop the efficient low-cost micro-forming method in batch. This paper introduced the state-of-the-art of sheet metal micro-forming technology with laser-induced ultra-high strain rate involving the loading modes, processes and forming fundamental. Then, the application of the micro-forming of ultra-high strain rate induced by laser shock is extended into the bulk forming domain, micro bulk forming. It is pointed out that the further investigation on micro bulk forming method focuses on scale effects, forming mechanism, loading and control modes.
