Water pollution is still one of the leading causes of death in developing countries. Equipment capable of measuring and improving water quality is urgently needed, especially in remote areas. In a paper entitled "Portable device for the detection of colorimetric assays," a group of researchers from the University of British Columbia discusses how they used 3D printing to create an inexpensive, portable diagnostic device for rapid water quality, acidity and nitrate concentration detection.
In other cases, 3D printing is used to develop equipment to measure and/or improve water quality. The 3d printing material was developed earlier this year with the potential to move pollutants from water and air, and the idea of simple water filtration systems from college students to primary school students, using 3d printing technology for prototypes or production to reduce costs and time. The device, developed by researchers at the university of British Columbia, does not filter or clean water, which is currently only a proof of concept, but it shows many hopes of detecting harmful pollutants in the water, potentially preventing disease and death. Its portability means it can be used easily in remote areas where water quality testing is most critical, and its easy, inexpensive manufacturing means it can be deployed quickly around the world.The proof of this concept also has great application potential in agriculture and medicine.
