Our project solves the problem desalination plants bring by eliminating the negative effects of dumping toxic brine into the ocean. Brine is the byproduct of reverse-osmosis, the process desalination plants all over the world utilize to create fresh drinking water. Our printer is just a prototype, illustrating our essential goal of 3D printing housing by using brine while cheapening the cost of making other construction materials. This printer will be using a coaxial extruder to create its prints. The extruder combines two different materials to make one cohesive filament to print with. By using a modified printer with this attachment we should be able to create the print and complete our goal.
