Title:
LIGHT-CURING THREE-DIMENSIONAL PRINTING PREVIEW METHOD
Document Type and Number:
WIPO Patent Application WO/2021/077493
Kind Code:
A1
Abstract:
A light-curing three-dimensional printing preview method, comprising the following steps: obtaining the relationship curves of the conversion rate of a photosensitive resin system versus time under different curing conditions by means of measuring the relationship between the absorbance of the photosensitive resin system under different curing conditions and the time; conducting fitting on experimental curves on the basis of a light-curing kinetic equation by means of an iterative solution method, and obtaining a light-curing kinetic constant of the photosensitive resin system; solving a light-curing reaction kinetic differential equation set by using a fixed-step Euler method, and obtaining the relationship curves of the space distribution of each component content of the photosensitive resin system in the light-curing reaction process versus time; and conducting simulation printing, in conjunction with the relationship curves of the space distribution of each component content versus time, obtaining a space distribution of each component content in each layer of structure in a three-dimensional printing product after printing is completed, and completing a light-curing three-dimensional printing preview, thereby filling the gap of three-dimensional printing control software in respect of the preview function.
