Aluminum samples were additive manufactured with different laser conditions, such as the scan speed, hatch distance, scan interval, and laser power. The effects of various laser conditions on the electropolished surface were studied. It was found that the laser power was of critical importance for the electropolished surface quality. This is because the final polished surface is closely related to the initial surface quality which was mainly determined by the applied laser power.

铝样品用不同的激光条件增材制造，例如扫描速度、舱口距离、扫描间隔和激光功率。研究了各种激光条件对电解抛光表面的影响。结果表明，激光功率对电抛光表面质量有着重要的影响。这是因为最终抛光表面与初始表面质量密切相关，初始表面质量主要由所施加的激光功率决定。
