Description

technical field

[0001] The invention belongs to the technical field of 3D printing, and in particular relates to a high-performance 3D printing piezoelectric part and a preparation method thereof. Background technique

[0002] 3D printing technology is a non-traditional advanced manufacturing method that has developed rapidly in recent years based on CAD model data by adding materials layer by layer. Selective laser sintering (selective laser sintering, SLS) technology is one of the main technologies of 3D printing. It uses computer-controlled high-energy laser beams to melt powder materials, bond them into thin layers, and stack them layer by layer to prepare three-dimensional parts. It has high molding accuracy, With the characteristics of high material utilization and no need for support, it can prepare parts with complex shapes that cannot be prepared by traditional processing. It is widely used in high-tech fields such as aerospace, medical equipment, and personalized c...
