The latest research on zirconia ceramic DLP ceramic 3D printing.

 

Zirconia ceramics have become key materials in the aerospace and military defense fields due to their excellent thermal stability, corrosion resistance and wear resistance. The method of combining ceramic materials with specific structural designs (lattice structures) to increase the service limit of materials has attracted extensive attention from researchers. Recently Professor Li Ling from Shandong Industrial Ceramics Research and Design Institute published an article titled "Lightweight high-heat-resistance zirconia ceramic lattice screws" in Ceramics International prepared by photocuring 3D printing technology. They used finite element simulation to design and select a lattice model with low thermal conductivity, fabricated it using DLP ceramic 3D printing, and experimentally verified its mechanical properties.

The rapidly developing ceramic 3D printing technology enables products to have complex and multi-scale geometric shapes, providing a new solution for the preparation of complex lattice ceramic products. The research focuses on the technology of preparing lightweight and heat-resistant zirconia ceramic lattice screws using DLP3D printing technology. Firstly, through finite element simulation technology, a lattice structure suitable for 3D printing and with both thermal and mechanical properties meeting the requirements is selected. Then, through 3D printing technology, a ZrOceramic screw with excellent mechanical and thermal properties was designed and fabricated, and the screw was filled with a unique lattice structure inside.

Research methods and data on the production of zirconia ceramic screws by DLP ceramic 3D printing

 

In this paper, a low thermal conductivity and lightweight ZrOlattice model was first designed and selected through finite element simulation. Then, M10 zirconia ceramic lattice screws were fabricated and formed using ZrOslurry and photopolymerization 3D printing technology. The main conclusions can be summarized as follows:

(1) Through simulation and experimental screening, a ZrOlattice structure with a cell size of 3 mm square and a wire diameter of 1 mm was optimized. The heat transfer temperature at its tail was 79.184 , which was 98.654 lower than that of the solid ZrOstructure. The filling rate of the ZrOlattice structure is 74.10%, which is 25.90% lower than that of the solid structure. In addition, the flexural strength of this ZrOlattice structure can reach 433 MPa.

(2) Through the above screening and optimization, the preparation and molding of lattice-filled M10 standard screws were completed, achieving the transformation from theoretical simulation to component application, which is conducive to further promoting the application of ZrOin the aerospace field.
