Abstract

The rapid growth of 3D printing has led to many new iterations of additive manufacturing techniques. However, the current 3D printing techniques encompass only one printing method and have gradually expanded the ability to print multiple materials simultaneously. In this research, a hybrid 3D printing system is created by integrating direct ink writing (DIW) into volumetric additive manufacturing (VAM) to achieve multi-material printing. Compared to traditional DLP and SLA printing systems, the hybrid DIW-VAM system can create parts 95% faster. Meanwhile, the developed hybrid system takes advantages of DIW's precision to suspend a secondary liquid resin through extrusion into a glass cylinder containing a primary UV photopolymer resin. The suspended UV photopolymer resin has a tensile strength of 50 MPa while the primary UV photopolymer resin is a flexible photopolymer material with a tensile strength of 5.5 MPa. Such a dual-material printing capability can create a part with two different mechanical properties in a 3D-printed structure. From the perspective of potential applications, the hybrid DIW-VAM printing system could create artificial human organs with complex geometries and internal structures that are made of different materials. It can also be used to create interlocked or embedded structures such as building a soft flexible structure over a curved hard-core material or integrating a sensor network into 3D-printed structures.
