Additive layer manufacturing (ALM) has revolutionised the near-net-shape fabrication of precision componentsand advanced cellular and microlattice materials in industries such as aerospace, automotive & medicaldevices. The laser is the primary component and expense in ALM machines but despite high costs (>£25k), thecost and performance of current laser sources particularly for stereolithography result in manufacturingcosts only supporting prototyping. Applied Materials Technology and Euriscus Ltd seek to address thisrequirement through a novel enabling laser technology for stereolithography with a radical improvements tothe cost, power density, compactness, stability, switching speed, reliability, longevity, tuneability, compactnessand electrical efficiency. The step change in the expense, functionality, performance and size of lasers forstereolithography will significantly improve laser scanning speeds, improve part quality and bring opportunitiesto introduce high speed raster scanning systems to promote ALM as an industrial production technology fornovel components and advanced materials.

在航空航天、汽车和医疗设备等行业中，附加层制造(ALM)彻底改变了精密元件和先进的细胞和微晶格材料的近净形状制造。激光器是ALM机器的主要部件和费用，但尽管成本很高(&gt；GB 25k)，当前激光光源的成本和性能，特别是用于立体光刻的激光光源，导致制造成本仅支持原型制造。应用材料技术和Euriscus有限公司试图通过一种新型的激光立体光刻技术来满足这一要求，该技术在成本、功率密度、紧凑性、稳定性、切换速度、可靠性、寿命、可调性、紧凑性和电效率方面都有根本改进。用于立体光刻的激光器在价格、功能、性能和尺寸方面的阶段性变化将显著提高激光扫描速度，改善零件质量，并带来引入高速光栅扫描系统的机会，以促进ALM作为一种新型元件和先进材料的工业生产技术。
