基于一般快速成型原理，采用激光熔化同轴输送的316L不锈钢粉末，在沉积基板上逐层堆积出薄壁金属零件，所制零件组织致密，成分均匀，具有快速凝固组织特征，力学性能与铸态及铸造退火态相当，可满足直接使用要求。
Based upon the mechanism of conventional rapid form, the thin wall parts of 316L stainless steel were obtained through the laser melting of metallic powders which were delivered coaxially and then deposited on the substrate layer by layer. The obtained microstructure is fully dense and evenly distributed with the characteristic of rapid solidified microstructure. The mechanical properties are equivalent to that of casting and wrought annealed materials, suitable to the requirement for real usage.
