Claim 0:
1. A system for printing biological materials comprising:
a bioprinter communicatively coupled to a processor and non-transitory memory comprising instructions to control the operation of the bioprinter;
the bioprinter further comprising:
a first cartridge configured to store a cell-laden material;
a second cartridge configured to store a hydrogel;
an electromagnetic radiation (EMR) module configured to emit EMR;
a modified surface configured to receive a deposited material, the modified surface comprising a polydimethylsiloxane (PDMS) coating; and
a dispensing mechanism coupled to the cartridge configured to dispense and distribute the cell-laden material and the hydrogel onto the modified surface, wherein the dispensing mechanism comprises:
an atomizer needle couplable to the second cartridge, and
a brush configured to distribute the deposited material on the modified surface, the brush configured to form a pattern in the deposited material as it is distributed on the modified surface;

wherein the instructions, when executed by the processor, cause the bioprinter to:
dispense, via the dispensing mechanism, the cell-laden material onto the modified surface,
dispense, via the atomizer needle, the hydrogel onto the dispensed cell-laden material up to a predetermined amount, wherein the brush forms the pattern in the hydrogel as it is dispensed, and
cure, via the EMR module, the dispensed cell-laden material and the dispensed hydrogel.
