Additive manufacturing (AM) with high-performance polymers (HPPs) represents simultaneously one of the most desirable and challenging feats in the AM arena. The very properties that make HPPs so attractive in a broad range of applications also make them nearly impossible to process using common AM equipment. Furthermore, when AM is achieved, it often brings the caveat of compromised mechanical properties of the final parts, in comparison with those made via injection molding. The demand to have advanced fabrication methods, rapid prototyping, and customization of parts while maintaining high performance in the finished products has inspired creative innovations that integrate chemical synthesis, materials science, mechanical engineering, and other fields into a multidisciplinary approach to advance AM with the seemingly “unprintable” HPPs. In this Viewpoint, we summarize several standout developments in the area and offer our perspective on future directions and challenges.

高分子科学观点 100 周年：将化学与工程相结合，用高性能聚合物实现增材制造

使用高性能聚合物 (HPP) 的增材制造 (AM) 同时代表了增材制造领域最令人向往和最具挑战性的壮举之一。使 HPP 在广泛的应用中如此具有吸引力的特性也使得它们几乎不可能使用普通的 AM 设备进行加工。此外，当实现增材制造时，与通过注塑成型制造的部件相比，它通常会带来最终部件机械性能受损的警告。在保持成品高性能的同时拥有先进的制造方法、快速原型设计和零件定制的需求激发了创造性创新，将化学合成、材料科学、机械工程和其他领域整合到多学科方法中，以推进 AM看似“不可打印”的 HPP。
