3D bioprinting is a relatively new concept of 3D printing. 3D bioprinting of organ printing has gained a huge attraction over the past 10 years. It has potential to be the future of tissue engineering and regenerative medicine. Bioprinting involves a 3D printing process to fabricate scaffold structures with live cells. However, it is still distant from being something the mass people could experiment with. The goal of this project is to bring cheap and reliable 3D bioprinters to the masses. This allows schools to be able to acquire 3D bioprinters for undergraduate students. This will open the opportunity for commercial use in the industry and research laboratories. Over the past 15 years, traditional FDM 3D printing has become available to consumers around the world. Because of this, many open source firmware’s exist. These firmware’s are heavily documented and customizable. Being able to repurpose desktop 3D printers to print biomaterials will open a pathway for technological innovation. 


In this research, Creo 3D modeling was used to develop 3D design for the biomaterial extruder head and pneumatic dispensing system. We have designed a pneumatic biomaterial dispensing system with multiple independent extruders suitable for a wide range of biocompatible hydrogel materials. The control system integration with designed 3D bioprinter lets synchronously control the gantry and dispensing system to tell the extruder where to print. Proper quality system restraints will be used to make sure all the specifications are up to standard to allow for proper construction of the gantry.  


The advancement of 3D printing has brought in the availability of biomaterial printing. Constructing this bioprinter will allow for a cheaper option over the already made printer which are much higher in price. Using proper engineering standards and technical designs will ensure for a functional and affordable 3D bioprinter printer.
