Researchers from the Iranian Research Organization for Science and Technology have designed and produced dual-nozzle 3D printers that allow two-color prints with application in medical field.
Shahin Khoshsokhan, the project manager, said while most 3D printers developed in the country are limited to just one nozzle and one color, his project is aimed at developing dual-nozzle printers that allow two-color prints, Mehr News Agency reported.
3D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. This type of printing is achieved using an additive process, where successive layers of material are laid down in different shapes.
“This 3D printer has two motors mounted at the back, which bring the materials to the nozzle. The dual-nozzle option allows the final design to be constructed without having the flow interrupted,” he said. According to Khoshsokhan, his 3D dual-nozzle printer has seven motors, a metal body and does not shake at all while working. "The 3D printer is able to construct a design in 22 x 15 x 15 centimeters," he said. Khoshsokhan noted that 3D printing can have applications in improving education in schools, universities, dentistry and jewelry-making among other fields. Iranian researchers obtained the technology to develop 3D printers in 2013, making the Islamic Republic first in the Middle East to have achieved this technology.
