A new method of microscale 3-D printing features in-situ resin mixing, delivery and exchange, and a robotic material cleansing system to allow switching between materials of different modulus, or flexibility, without cross-contamination between properties. The method, called multi-material programmable additive manufacturing with integrated resin delivery, is featured in the journal Scientific Reports. The technology could be … Continue reading 3-D printed multimaterial with programmed stiffness
