Bioprinting Industry Highlights of Q2 2018

New Methods
Researchers at UCLA, Harvard, UC San Diego, University of Santiago de Compostela, Brigham and Women’s Hospital, and Sharif University of Technology have collaborated to create a stereolithographic bioprinting platform capable of printing with multiple materials [1]. This novel device utilizes a digital micromirror device, a moving stage, and a microfluidic device with four pneumatic valves to rapidly switching between various bioinks for multimaterial printing [2]. The micromirror incorporates a UV lamp, digital mirroring device chipset, Keplerian optical setup, and a microscope objective to focus and adjust light intensity on a DMD chip [3]. The light beam is generated into different patterns on the chip using CAD. The microscopic objected focuses the selected pattern at the optimal length where photosensitive hydrogels can be be exposed to UV light to crosslink, solidify, and create complex structures [4]. While the bioprinter has successfully demonstrated printing with f…
