Problems solved by technology

[0002] As an important symbol of the third industrial revolution, 3D printing technology has been applied to many fields with its characteristics of personalized manufacturing and additive manufacturing. Among them, the additive manufacturing of resin materials is one of the main directions of 3D printing, but for transparent resin Materials are still a technical problem to be solved urgently
The University of Washington has also developed a 3D quantum dot LED printer and a contact lens with a built-in display, but it is not yet suitable for the manufacture of transparent optical resin lenses

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] see figure 1 , the present invention comprises the following steps:

[0026] Step 1. According to the visual inspection parameters of myopia patients and the refractive index of the selected material, the three-dimensional model is designed according to the requirements of optical design to realize individual optical correction, and the simulation optimization is carried out in Zemax optical design software;

[0027] Step 2: Select a transparent resin material whose refractive index and other parameters meet the optical performance, and can realize 3D printing;

[0028] Step 3: Determine the 3D printing process according to the performance parameters and molding requirements of the resin material;

[0029] Step 4: According to the material performance parameters of the resin material, the printing model and the characteristics of the printer, set the appropria...

Abstract

The invention discloses a method for printing an individual myoporthosis resin lens based on 3D. Firstly, three-dimensional model individualized design is carried out according to myopia check parameters of myopia patients; secondly, WaterShedRXC 11122 transparent resin materials are adopted, meanwhile, printing parameters are set, and a photocuring forming process is used for conducting 3D printing; and thirdly, the molded lens obtained after printing is subject to follow-up treatment including polishing, grinding and burr removing. The transparent lens printed through the method can achieve individual high matching of the myopia patients, and can reduce optical correction loads of the high myopia patients; and meanwhile, a way and method of application of the transparent lens for hook face lens molding are achieved.

Description

technical field [0001] The invention belongs to the field of 3D printing, in particular to a method based on 3D printing individual myopia correcting resin lenses. Background technique [0002] As an important symbol of the third industrial revolution, 3D printing technology has been applied to many fields with its characteristics of personalized manufacturing and additive manufacturing. Among them, the additive manufacturing of resin materials is one of the main directions of 3D printing, but for transparent resin Material is still a technical problem to be solved urgently. According to the survey, the optical correction lenses manufactured by the existing traditional technology have low adaptability, resulting in incomplete correction for the glasses wearers; in addition, since there is no mold for correcting lenses for patients with high myopia, the cost of all manual glasses is high. This invention intends to realize the molding and manufacturing of individual myopia co...
