Light curing preparation device of gradient material and light curing preparation method

Abstract

The invention discloses a light curing preparation device of a gradient material. The device comprises a horizontal motion table, a light curing system, a horizontal driver, an upper and lower mobile station, and an upper and lower driver. The invention also discloses a light curing preparation method based on the device. The method is as below: first, modeling a biological functionally gradient material to obtain a model; then calculating the contour information of each layer of the model by the 3D printing layered software, and generating light curing code by using the contour information; then, placing different light curing composite solutions in different solution baths; and at last, controlling the light curing device according to the code for light curing molding to prepare the graded material, so as to realize proportion control of the gradient material.

Description

technical field [0001] The invention relates to the field of preparation of gradient materials, in particular to a photocuring preparation device and a photocuring preparation method of gradient materials. Background technique [0002] Biofunctionally graded materials (bio-FGM) are heterogeneous composite materials whose raw material components, material composition and properties change continuously or discontinuously along the thickness or length of the material. In recent years, the development of medicine has led to a corresponding increase in the requirements for medical biomaterials. Therefore, the research and development of novel and feasible biofunctional gradient materials and their preparation equipment has gradually become a frontier topic in the current medical field. Because human bones, teeth, and joints have the characteristics of high hardness, wear resistance, and good toughness, artificial bones, knee joints, dental implants, and optimized hip prostheses m...

Problems solved by technology

[0008] However, there is uneven control of the proportion of each component in the preparation of biological functionally graded materials by the above-mentioned traditional technical equipment, and the actual value of Young's modulus of the prepared biologically functionally graded materials is different from the expected value of Young's modulus calculated according to the mixing law of composite materials. The values ​​are quite different, which will affect the quality and reliability of biofunctionally graded materials, and then affect the practical application.
