4/11/2023 0 Comments Ratchet and clank 3d print modelsTU Braunschweig researchers recently published another paper, “ Development of a Robot-Based Multi-Directional Dynamic Fiber Winding Process for Additive Manufacturing Using Shotcrete 3D Printing,” about their continued work in this area. Integrating structural reinforcement into 3D printed concrete components is a big challenge in the additive construction industry, and while a number of strategies are currently being investigated, such as manually inserting conventional steel reinforcement into a 3D printed lost formwork, simultaneous printing with wire arc additive manufacturing (WAAM) technology, injecting nails and screws to vertically connect layers, and more. Automated application of shotcrete (a) robotic shotcreting process (b) first results of robotically shotcreting a winded reinforcement mesh (front and rear).įor a few years now, researchers at the Technische Universität Braunschweig have been working to develop an automated method for integrating textile reinforcement with concrete additive manufacturing, using the novel Shotcrete 3D Printing (SC3DP) method developed at the university, which not only extrudes the material but also sprays it with pressure to build a vertical 3D structure.
