a) Schematic showing the microfluidic chip containing a moving part at the center of the bottom chamber. b) Computational domain of the finite element analysis built for an isotropic, incompressible, hyperelastic membrane supported on the rigid piston. c) Simulation result showing principle strain and stress values of the PDMS membrane at 4-mm displacement. d) Schematics showing the four-step bioprinting process inside the microfluidic chip for fabricating 3D objects. e-g) Examples of multi-component bioprinted constructs: e) a two-component GelMA-7% construct filled by fluorescent dyes (left) and a three-component pattern of colored PEGDA-50% (right); f) a 3D fluidic mixer made by three different colors (white, orange, blue) printed from PEGDA-50%; and g) a single-component (green) and a three-component (white, blue, purple) star-shaped pyramid of PEGDA-50%.
