The μCOP system and culture study parameters. a) Schematic of the μCOP system which consists of a programmable DMD, using digital masks to control millions of individual mirrors to pattern light onto a liquid volume. The computer controls the light source and exposure time and digital patterns which are paired with the high-precision stage to create 3D-scaffolds. b) Two sets of digital patterns including a simple set of parallel lines of 5% GelMA with encapsulated hESC-CMs. c) A multiprint mechanical tester including a HAGM base layer, 10% GelMA cantilevers, and parallel lines of 5% GelMA/hESC-CMs printed across the cantilevers.
