增材制造（AM）的革命为制造复杂和新颖的产品带来了许多机会。可打印材料的增加和新型制造工艺的出现不断扩大工程系统的可能性，其中产品组件不再限于单一材料，单一规模或单一功能。事实上，工业中正在发生一种范式转变，从以几何为中心的使用转向支持功能需求。因此，工程师需要解决与功能设计相关的各种复杂和困难的问题。虽然AM已经实现了超越几何的更高程度的设计自由度，但在这个新的AM使能领域中，只有很少的计算设计方法可以设计具有定制属性和功能的对象。本综述的目的是概述最近的增材制造发展和当前的计算机辅助设计方法，可应用于多材料，多尺度，多形式和多功能AM技术。总结了计算设计方法中遇到的困难，并强调了未来的发展需求。本文还讨论了增材制造技术的一些当前应用和未来趋势。
The revolution of additive manufacturing (AM) has led to many opportunities in fabricating complex and novel products. The increase of printable materials and the emergence of novel fabrication processes continuously expand the possibility of engineering systems in which product components are no longer limited to be single material, single scale, or single function. In fact, a paradigm shift is taking place in industry from geometry-centered usage to supporting functional demands. Consequently, engineers are expected to resolve a wide range of complex and difficult problems related to functional design. Although a higher degree of design freedom beyond geometry has been enabled by AM, there are only very few computational design approaches in this new AM-enabled domain to design objects with tailored properties and functions. The objectives of this review paper are to provide an overview of recent additive manufacturing developments and current computer-aided design methodologies that can be applied to multimaterial, multi-scale, multiform, and multifunctional AM technologies. The difficulties encountered in the computational design approaches are summarized and the future development needs are emphasized. In the paper, some present applications and future trends related to additive manufacturing technologies are also discussed.
