Effect of Infiltrating Action on the Mechanic Property for 3DP Technology

Abstract

Three-Dimension Printing(3DP) technology integrates computer aided design and manufacturing (CAD, CAM), automatic control technology and digital printing technology. The ink with bonding function contained in the nozzle is used as the binder, which is sprayed on the medium powder as needed to bond and form, and is widely used. The precise forming of inorganic powders such as gypsum can be realized by 3DP technology, but the mechanical properties of the technology are poor due to many factors. The infiltrating action in the reprocessing process is considered as the research object, the effects of infiltration times, infiltration modes, and infiltration interval on mechanical properties are explored by the compressive strength, SEM, and EDS, where the compressive strength is measured by materials testing machine. The experimental results show that the mechanical properties of the formed parts can be effectively improved by multiple infiltrations and gradually increasing the infiltration interval. The research results provide a reference for the infiltration action of post-treatment of 3DP formed inorganic powder materials.
