3D Printing Technology Could change the Optical Fibre Industry

3D printing of silica glasses and silica optical fiber preforms has recently been proved experimentally. One challenge of 3D printing silica optical fibers performance is how to extend the recent reports of small-scale glass “bulk or slice” printing from a few millimeters to centimeters.


Dr. Yushi Chu and Prof. Jianzhong Zhang of Harbin Engineering University (HEU), and Prof. Gang-Ding Peng of the University of New South Wales (UNSW) led a research team to extend small-scale glass printing by several orders of magnitude. The paper, titled “Additive Manufacturing Fiber Preforms for Structured Silica Fibers with Bismuth and Erbium Dopants,” proved that optical fiber preforms could be made through 3D printing.


The centimeter-scale optical fiber preform was successfully fabricated by DLP 3D printing technology, and single-mode and multi-mode optical fibers were obtained by controlling the parameters during fiber drawing. On this basis, the research group further extended this work, bismuth ions and erbium ions were co-doped into the single-core and seven-core fibers. They realized the fabrication of multi-component fibers and structured fibers. For further information see the IDTechEx report on 3D Printing Hardware 2022-2032: Technology and Market Outlook.
