The utilization of the microfabrication technique to fabricate advanced computing chips has exponentially increased in the last few decades. Needless to say, this fabrication technique offers some unique advantages to develop micro-systems. Though many conventional microfabrication techniques today uses very harsh chemicals, the authors believe that the manipulation of system components and fabrication methods may aid in the utilization of the microfabrication techniques used in fabricating computer chips to develop advanced biological microfluidic systems. Presented in this paper is a fabrication approach in which popular fabrication methods and techniques are coupled together to develop an integrated system that aids in the fabrication of cell-laden microfluidic systems. This system aims to reduce the uses of harsh chemicals and decreases the lengthy fabrication time. Additionally, this integrated system will enable the printing of cells as the microfluidic chip is being fabricated. To demonstrate the unique capabilities of the integrated system, an advanced microfluidic chip is being fabricated and investigated. The advanced chip will feature the investigation of cancer cells in a co-cultured microfluidic environment. The investigations presented demonstrate cocultures in a microfluidic chip, advanced cell printing with localized surface enhancement, cell integration, and full additive fabrication of a microfluidic chip.
