Multi-Scale and Multi-Material Additive Manufacturing
报告摘要：
Manufacturing has long been a cornerstone of human life and a driver of transformative technological advancements. Additive Manufacturing (AM) has been recognized as a disruptive force across industries by enabling the creation of 3D objects with unprecedented geometric complexity and heterogeneous material properties. In the medical field, AM has enabled the fabrication of multi-scale structures, such as patient-specific implants with intricate micro-scale features that promote cell growth and macro-scale designs tailored to individual anatomy. Meanwhile, in aerospace engineering, AM has facilitated the creation of multi-material components, such as lightweight structures with integrated heat-resistant alloys and advanced cooling systems for improved performance. Such manufacturing capabilities open up new avenues for solving engineering problems. However, fabricating multi-scale and multi-material structures demands the integration of micro-, meso-, and macro-scale manufacturing processes and effective methods to process various engineering materials, which remains an ongoing challenge. In this seminar, Dr. Xu will delve into multi-scale and multi-material AM from a process-oriented perspective and present his methods for tackling the critical challenges in manufacturing.
制造业长期以来一直是人类社会发展的重要支柱，也是推动技术变革和产业进步的核心动力。增材制造（Additive Manufacturing，AM）因能够制造具有前所未有几何复杂性和异质材料特性的三维结构，被公认为具有颠覆性影响的先进制造技术。在医疗领域，增材制造实现了多尺度结构的制造，例如兼具微尺度精细特征和宏观个性化外形的患者定制化植入体。其中，微尺度结构能够促进细胞生长与组织再生，而宏观结构则可根据患者解剖特征进行精准设计。与此同时，在航空航天领域，增材制造推动了多材料构件的发展，例如将轻量化结构、耐高温合金以及先进冷却系统集成于同一部件中，从而显著提升装备性能。这些先进制造能力为解决复杂工程问题开辟了新的途径。然而，多尺度、多材料结构的制造需要有效融合微观、中观和宏观尺度的制造工艺，并实现对多种工程材料的高效加工与协同制造，这仍然是当前增材制造领域面临的重要挑战。
在本次报告中，徐阳教授将从制造工艺的视角深入探讨多尺度与多材料增材制造技术的发展现状与关键问题，重点介绍其团队在突破相关制造瓶颈方面所提出的方法与研究成果，并分享面向未来先进制造应用的发展思路与技术展望。
