Development of an innovative composite 3D printer Fig. 2: " Core shell " method - printing procedure Fig. 3: Printed Sample by " core shell " method expected to become usable for applications that were previously considered to be incompatible with existing 3D printers. For example, it is expected to be used in the manufacture of resin parts for sports equipment and nursing care products that require high physical properties while being lightweight, prototypes that require high rigidity and strength, and in situ manufacturing of jigs for factories. Toray Engineering will continue to work on the development of composite 3D printers to expand the market and further promote the use of composite materials.
