Abstract

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.

摘要

熔体电写（MEW）是一种新兴的高分辨率添加剂制造技术，基于聚合物的电流体动力学加工。MEW主要用于制造生物医学应用的支架，其中微尺度纤维定位在其宏观力学性能方面具有重要意义。本综述介绍了通过MEW加工的越来越多的聚合物以及金标准聚(ε-己内酯)（PCL）的不同商业来源的最新情况。介绍了PCL以外的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，强调了打印机设计和开发的前景，以不断扩大MEW可加工聚合物的种类。
