Melt electrowriting (MEW) is an emerging high-resolution additive manufacturing technique based on the electrohydrodynamic processing of polymers. MEW is predominantly used to fabricate scaffolds for biomedical applications, where the microscale fiber positioning has substantial implications in its macroscopic mechanical properties. This review gives an update on the increasing number of polymers processed via MEW and different commercial sources of the gold standard poly(ε-caprolactone) (PCL). A description of MEW-processed polymers beyond PCL is introduced, including blends and coated fibers to provide specific advantages in biomedical applications. Furthermore, a perspective on printer designs and developments is highlighted, to keep expanding the variety of processable polymers for MEW.
熔体电写（MEW）是一种基于聚合物的电流体动力学加工的新兴高分辨率增材制造技术。MEW主要用于制造生物医学应用的支架，其中微观尺度的纤维定位对其宏观力学性能有重大影响。本文综述了通过MEW加工的聚合物数量的增加以及金标准聚己内酯（PCL）的不同商业来源。介绍了除PCL之外的MEW加工聚合物，包括共混物和涂层纤维，以在生物医学应用中提供特定优势。此外，还强调了对打印机设计和开发的展望，以不断扩大MEW可加工聚合物的种类。
