Research On Crystallize Printing Construction And Design Based On Finite Element Analysis

The system that combines the robotic arm platform with lattice-based printing can achieve the goal of printing large-scale building components and entire buildings in a single print in the field of architecture.By combining structural optimization techniques with the 3D printing technology based on the robotic arm spatial positioning platform,the advantages of both can be maximized.The advantage of the robotic arm platform is its ability to flexibly approach any position in space from different angles,and it has a programmable control for automated processes.The advantage of 3D printing technology is its ability to print complex-shaped building components using simple linear paths.This study is based on the wide-ranging application scenarios of robotic arm lattice printing,and uses finite element simulation to analyze the mechanical structure,as well as digital simulation analysis and printing tools based on Rhino-Grasshopper platform.Through the structural analysis of the length and type of unit paths,the specific operation method of spatial printing is more closely related to the actual printing.Different additive materials and printing methods are also analyzed.Then,different shapes of components are established based on a large number of structural analysis simulations and data.The optimized generation method of variable crosssection shells proposed in this paper provides a design idea for the overall form of lattice printing structure.In the process of actually printing these components,a series of structural performance optimization and printing path optimization were carried out.The distributed optimization method used in this paper improved the overall structural performance,and the stiffness of the overall lattice printing building based on the distributed optimization design method was greatly improved.The discrete path planning method was used for the printing path,which has better editability compared with the common continuous space printing path planning method.The nodes in the unit path were also optimized for stiffness improvement.Finally,we summarized and experimented with the optimization methods mentioned in this paper based on an actual case,and provided a complete set of methods for spatial lattice printing.Through robotic arm lattice printing technology,not only can the appearance of buildings be enriched,but also the printing components can no longer be limited to decorative purposes,but can be used for spatial building structural components.The application of this technology will greatly improve the feasibility of printing buildings and bring more possibilities to the construction industry.Architects can explore the non-linear structures and emerging technologies in buildings,as well as opportunities and challenges in the practical process.Finally,this paper briefly discusses and summarizes the remaining problems and future work suggestions in this research.
