METHOD OF LASER-FORMING ALUMINUM

摘要

A method of laser-forming aluminum, the specific steps thereof comprising: step 1, utilizing a computer establishing a geometric model and generate a forming track; step 2, prepare a vacuum or a protective gas machining environment; step 3, provide a raw material to a machining region, and utilizing a laser having a wavelength of 700-900 nm, melt the provided raw material; step 4, determine whether or not machining is complete, and if not, enter step 3 and scan a next layer, and if so, enter step 5; step 5, clean and recover an excess of the provided raw material; step 6, remove a product. The method fully utilizes the high absorbance of aluminum, aluminum alloys and aluminum-based composite materials with respect to a laser having a wavelength of 700-900 nm, reducing as far as possible the reflection of the laser by the aluminum, aluminum alloys and aluminum-based composite materials, resulting in a high energy utilization efficiency of the forming process, rapid forming, and high forming accuracy, realizing faster 3D printing.
