A light curing gradient material forming device and method

Abstract

The invention discloses a light-curing gradient material forming device and method. By setting a light-curing groove at the lower end of the forming platform, the forming platform is set on the upper end of the light-curing groove through a vertical driving device, and a light-curing molding lamp is arranged at the lower end of the light-curing groove The light-curing molding material required for printing is placed in the photo-curing tank; the mixing tank is connected with a feeding mechanism to realize the density adjustment of the photo-curing molding material. The flow of the light-curing molding material in the light-curing tank realizes the preparation of the gradient material. The device has a simple structure, simplifies the preparation process of the traditional gradient material, reduces the manufacturing cost, and reduces the required conditions for the formation of the gradient material. The operation is simple. The device can realize the preparation of density gradient materials with different performance requirements, only need to add different fillers in the filler tank, and add different fillers to improve the performance requirements of different parts.

Description

technical field [0001] The invention relates to the technical field of gradient material preparation devices, in particular to a photocuring gradient material forming device and method. Background technique [0002] With the continuous development of high technology and the continuous change in the field of material science, density gradient materials have emerged as the times require. Density gradient material is a kind of functionally gradient material whose density changes gradually along the thickness direction. According to specific requirements, the functions of two or more sides can be realized under the premise of ensuring the integrity of the material, so as to meet the performance requirements of parts in different occasions. [0003] The preparation methods of density gradient materials include: chemical vapor deposition method, self-propagating high temperature synthesis method, plasma spraying method, powder metallurgy method, centrifugal casting method and film...

AI Technical Summary

Problems solved by technology

For example, there are problems such as the interface with a sudden change in composition and the low bonding strength of each coating between the coatings of the plasma spraying method; the vapor deposition method can only prepare thin layers, and it is difficult to obtain large-scale materials with a certain thickness; in addition, this type of preparation method process Complex, requires large equipment, cannot be carried out in the laboratory, and the cost is high, which is not conducive to research and production
