Research on the Application of Discrete Minimal Surfaces in 3D Printing

Abstract

As a new disruptive technology in the manufacturing industry, 3D printing can meet personalized customization through the application of discrete minimal surfaces, providing a smooth channel for connecting with a large number of users, which has important practical value. Based on the design foundation of discrete minimal surfaces structure, 3D printing technology was used to produce porous TC4 titanium alloy with discrete minimal surfaces. The microstructure changes and compressive properties of the samples were compared and observed in diff erent states of deposited microstructure and after heat treatment. After research, it was found that using Rhino modeling software and the Grasshopper plugin, a discrete minimal surface model was generated. Further processing was carried out using 3-matic topology optimization software, which then processed the multi porosity of the discrete minimal surface. The compressive strength of the porous TC4 titanium alloy with discrete minimal surface increased with the increase of apparent density. The research results provide an important foundation for subsequent research.
