Development of an intuitive visualization system for measuring the melt electrowritten (MEW) jet diameter along the spinline

Melt electrowriting (MEW) is a young and promising additive manufacturing technology for producing high-precision scaffolds. In this study, we develop an intuitive visualization system enabling users to measure MEW jet diameters along the spinline without programming knowledge. The digital measurement adopts the same theory as our reported manual measurement. The maximum error between the digitally and manually measured data is smaller than 9%, suggesting that the open-source system developed here is reliable in measuring jet diameters.
