3-D printing improves cell adhesion and strength of PDMS polymer
Most research is done using casting or micro molding, but this fabrication yields materials with weak mechanical properties and also weak cell adhesion. PDMS is used to make lab-on-a-chip devices, organ-on-a-chip devices, two- and three-dimensional cell culture platforms, and biological machines. Sylgard 184, an elastomer of PDMS, is not viscose enough to use in 3-D printing-the material simply flows out of the nozzle and puddles.
