(A) Overview of the experimental set-up composed of a 12-well plate, 3D printed silicone positioning systems, GelMa coated circular glass slides and printed patterns of NIH3T3 cells. (B) Overview of the theoretical printing patterns in printer software. (C) Printed drops (15 nL) of alginate hydrogel used to setup size and distance between droplets. (D) Printed drops (15 nL) of NIH3T3 immediately after bioprinting. (E) Close-up image of the bioprinted nozzle filled with NIH3T3 cells. Scale bars: 500 μm.
