Abstract: A 3D printing system can include an extruding system, curing system and feedback system. The extruding system can include a feed pipe coupled to a printing material source and a nozzle that extrudes a printed material. The feedback system can include a processor and sensors and can detect the temperature and location of the curing system during the printing process. The curing system cures the printed material after extrusion and includes curing sources coupled to a mounting arrangement, which can be a curved surface. The curing sources can each be directed toward a focal region located proximate the nozzle outlet and can combine to emit a combined curing energy to the focal region. The curing sources can be LEDs and the curing energy can be UV light. The curing system can rotate about an axis during printing and curing to facilitate rapid movement and printing of complex 3D objects.
