3D printing has evolved quickly from rapid prototyping to true mass production. This is reflected in the use of the term additive manufacturing (AM) to emphasize the use of the technology in actual manufacturing of high-value products and finished goods. Consequentially, the requirements on the materials and processes have become more stringent and challenging to satisfy. Furthermore, various manufacturing industries have their own unique sets of requirements, and these are difficult if not impossible to satisfy with neat polymers alone. Therefore, additives are playing an increasingly critical role for satisfying material requirements for AM applications. In this article, challenges are identified that will need to be addressed as AM matures toward manufacturing applications. These include speed of production, mechanical performance and durability of the products, their interaction with the environment, and readiness for manufacturing. The use of additives to overcome these challenges is discussed in terms of current trends and with the help of specific examples. These include, but are not limited to, reinforcements, thermal stabilizers, antioxidants, and flame retardants to improve performance and meet thermal, environmental, and flammability requirements in demanding applications like aerospace, defense, and automotive. Further, colors, pigments, and dyes are needed for aesthetics. Bioactive or bioinert materials are needed for specific medical applications, and electrically dissipative or thermally conductive materials are often needed for electronics applications. This article provides a critical look at the current state of AM and how the roles of additives in AM are expected to expand, including identification of future opportunities.

添加剂在 3D 打印中的现状和未来作用——一个观点
3D 打印已经从快速原型快速发展到真正的大规模生产。这反映在使用增材制造 (AM) 一词来强调该技术在高价值产品和成品的实际制造中的使用。因此，对材料和工艺的要求变得更加严格和难以满足。此外，各种制造行业都有自己独特的要求，仅靠纯聚合物很难甚至不可能满足这些要求。因此，添加剂在满足增材制造应用的材料要求方面发挥着越来越重要的作用。在本文中，确定了随着增材制造向制造应用的成熟而需要解决的挑战。这些包括生产速度，产品的机械性能和耐用性、它们与环境的相互作用以及制造准备情况。根据当前趋势并在具体示例的帮助下讨论了使用添加剂来克服这些挑战。这些包括但不限于增强剂、热稳定剂、抗氧化剂和阻燃剂，以提高性能并满足航空航天、国防和汽车等苛刻应用中的热、环境和可燃性要求。此外，为了美观，还需要颜色、颜料和染料。特定的医疗应用需要生物活性或生物惰性材料，而电子应用通常需要电耗散或导热材料。
