The research aims to take an advantage of the knowledge from the past and integrate with today’s technology to construct novel and complex forms. The intention is to integrate fibers during the 3d printing process to support the cantilevers in wet state as well as find the optimized method to lay the fibers. This method may include the anchor points at various levels around the structure and digital tools to locate the optimized fiber locations and orientations.
The research focuses on the design and fabrication aspect of the optimized placement of fibers, to support the earth 3d printed cantilevers through digital analysis of the geometry, to identify the orientation of the fiber placement and evaluating the most feasible method to add fibers in the wet state during 3d printing.
Additives and fibers have been a significant part of the Earthen mixes, as they provide the necessary strength, binding properties, weather resistance as well as aesthetics to the structure.
The Geometry was modified to improve the stability and printability.
The real scale model was scaled down and added with the thickness of a double layer for stability. And infill was introduced to improve the slicing distance and printability of the geometry
Here we embeded fiber as a element to fix the weakest part of the geometry which is the edge. As it it regulates the deformation of the geometry, different pattens bring different stability as well as certain extra stiffness to the structure.
Here we realized to be able to using this tool, a structure simulation should be developed for example, fiber reinforcement in FEA, weak properties extraction and buckling model to verify the printing results.
Till now, a strong conclusion being established in terms of the phases of printing. The weak points are changing and shifting during the printing, the weakest point sometimes appears in the mid stage of producing.
