在航空航天、医疗、新能源汽车等高端制造领域，金属增材制造（3D打印）技术正发挥着越来越重要的作用。它能够快速制造复杂结构的零部件，大幅缩短研发周期，并降低生产成本。然而，尽管这项技术前景广阔，但其在实际应用中仍面临诸多挑战。
目前，基于激光粉末床熔融（laser powder bed fusion, LPBF）的金属增材制造大多通过激光扫描光斑实现加工。然而，传统激光光斑的能量分布呈高斯分布，即中心能量高、边缘能量低。这种不均匀的能量分布会使熔池产生很大的温度梯度，从而容易导致加工件表面出现毛刺，同时内部产生残余应力，影响零部件的精度和使用寿命。这些问题成为制约金属增材制造技术进一步发展的瓶颈。
为了解决高斯光斑带来的问题，业界提出了光束整形的方案。目前主要采用的技术路径包括：异形镜头、微透镜阵列和DOE（衍射光学元件）。然而，这些方案存在一个共同的缺陷——光束整形不可调。在实际应用中，不同材料、不同形状的零部件需要不同的光斑形态，而现有技术无法灵活调整光斑形状，也无法通过现有理论模型模拟找到最优解。因此，光斑的可调性成为制约这些方案广泛应用的关键问题。
理论上，空间光调制器（LCOS-SLM）可以完美解决光斑可调性的问题。它能够灵活调整光斑形状，适应不同的加工需求。然而，金属增材制造在加工过程中需要对金属颗粒进行熔化，因此对激光功率的要求极高，单光束功率需要超过300 W，而传统的空间光调制器无法满足这一功率需求。因此，空间光调制器在金属增材制造领域的应用一直处于空白状态。
直到2024年，滨松公司推出了700 W高功率LCOS-SLM，成功填补了这一技术空白。这款产品不仅承受高功率激光，还能实现灵活的光束整形，为金属增材制造提供了全新的解决方案。
为了让业界更深入了解700 W高功率空间光调制器在金属增材制造中的应用，滨松中国将于2月20日15:00举办一场专题直播讲座。本次讲座由滨松SLM算法开发者、资深工程师王梓博士主讲，将详细介绍滨松700 W空间光调制器，以及光束整形在金属增材制造中的多个实际案例，并将同时分享基于滨松空间光调制器的硬件模块方案、算法方案。从硬件到软件，从产品到应用，王梓博士会带领大家切实了解在实际应用中如何更好地发挥出空间光调制器的作用，实现更高质量的加工。
如果您对这个话题感兴趣，或正在寻找金属增材制造加工的创新方案，这场直播讲座将为您带来全新的视角和启发，更有惊喜福利待您抽取。立即报名，与行业同仁们共同见证金属增材制造的新可能吧！
