This article discusses how researchers have now been able to utilize standard red, green, blue, and violet LEDs instead of ultraviolet (UV) light to 3-D print objects with speed and detail, equaling that of cutting-edge printers. Prior to this discovery, the use of UV light to transform liquid resins into solid objects has been the most efficient way to craft intricately detailed objects in the world of 3-D printing. However, according to chemists, this new development could decrease the expense and vitality utilization of 3-D printing and could open a few novel applications.
