Three-dimensional printing was used to fabricate various metallic structures by directly integrating a Br-containing vinyl-terminated initiator into the 3D resin followed by surface-initiated atomic-transfer radical polymerization (ATRP) and subsequent electroless plating. Cu- and Ni-coated complex structures, such as microlattices, hollow balls, and even Eiffel towers, were prepared. Moreover, the method is also capable of fabricating ultralight cellular metals with desired structures by simply etching the polymer template away. By combining the merits of 3D printing in structure design with those of ATRP in surface modification and polymer-assisted ELP of metals, this universal, robust, and cost-effective approach has largely extended the capability of 3D printing and will make 3D printing technology more practical in areas of electronics, acoustic absorption, thermal insulation, catalyst supports, and others.
三维打印通过直接将含 Br 的乙烯基封端引发剂整合到 3D 树脂中，然后进行表面引发原子转移自由基聚合（ATRP）和随后的化学镀，用于制造各种金属结构。已经制备了 Cu 和 Ni 涂层的复杂结构，例如微晶格、空心球，甚至埃菲尔铁塔。此外，该方法还能够通过简单地去除聚合物模板来制备具有所需结构的超轻多孔金属。通过结合 3D 打印在结构设计方面的优点、ATRP 在表面改性方面的优点以及聚合物辅助的金属电沉积（ELP）的优点，这种通用、稳健且具有成本效益的方法大大扩展了 3D 打印的能力，并将使 3D 打印技术在电子、吸声、隔热、催化剂载体等领域更具实用性。
