The additive manufacturing (AM) industry has progressed a long way since the first rapid prototyping machines were invented with the launch of stereolithography and filament deposition method (FDM) 3D printers more than three decades ago. This talk will provide an overview of the state of the industry and industrialization journey, how it has progressed from rapid prototyping applications to playing an increasingly pivotal role as a manufacturing process enabling new product design paradigms and a wide spectrum of new emerging applications. As the green energy transition and decarbonization effort gather pace globally, developing more sustainable ways of production through circular design, resource efficiency and distributed manufacturing enabled by AM has become paramount. Despite the undoubted value proposition of AM technology being a more sustainable production method over traditional manufacturing using subtractive or formative methods, there remains formidable barriers to its adoption for mass manufacturing. For AM to establish itself as a viable method in modern manufacturing augmenting traditional manufacturing processes, the need for the industry to collaborate becomes paramount. This is especially needed in developing material specifications and technical references towards industry-driven standards in AM process qualification methodology - moving from part-based qualification, supported by the incorporation of digital process models. This will enable scalability and create confidence for increased end-use adoption through the reduction in AM part qualification and certification cost, lowering one of the barriers for the AM community to scale adoption.

铁和铝作为工业生产中最广泛应用的两种金属材料，已在我们日常生活中比不可少。金属增材制造技术，尤其是主流粉末床体系，在融入已有工业体系的过程中将不可避免的面对以铁和铝为基础的多种合金体系带来种种“挑战”与“机遇”。因此，理解这两种合金体系在粉末床增材制造技术过程中的材料与工艺特征将对粉末床增材制造技术的产业应用起到重要的推进作用。本次报告将以法国巴黎高科MSMP团队在该领域的几个产业应用实例为切入点进行讨论，将涉及新装备、新材料、与新工艺等方面。

在数字光处理打印中，离型膜的脱落方式决定了机器打印速度。通过建立多物理场模型，考虑离型膜大变形、光化学反应、流体运动、光固化相变、和氧阻聚等效应，研究离型膜脱落机理。并进一步提出图案光方案提高打印速度。

增材制造(AM)在航空航天工业中的应用，使得喷气发动机部件(包括涡轮叶片)等非常复杂的部件的生产可以使用增材制造工艺进行制造，而其他任何传统制造工艺都难以制造这些部件。然而，在打印过程中，无论大小，表面和边缘都可能出现缺陷，从而影响喷气发动机的性能和安全。针对精度差、效率不高的问题，我们提出了一种算法进行喷气发动机涡轮叶片表面、缺口和边缘缺陷检测的深度学习方法。该方法具有较高的精度和速度，是一种实用的增材制造涡轮叶片试件表面缺陷检测方法，成功地检测并识别了涡轮叶片数据集中的缺口、边缘缺陷和表面缺陷，与之前的自动缺陷识别过程相比，仅在0.078小时内就实现了高达99.5%的缺陷检测精度。
