Abstract

The invention discloses a 3D printing photosensitive resin for jewelry casting. The components and weight percentages are as follows: polyether acrylate resin 40%-60%; polyether monomer 30%-50%; photoinitiator 3% to 6%; UV absorber 0.5% to 5%; dye 0.02% to 0.15%; Initiator, ultraviolet absorber, dye and polymerization inhibitor are added into the reaction kettle according to the proportion of the formula, and stirred at a constant temperature of 70 ° C to 80 ° C for 0.5 to 1 hour. After the components are completely dissolved, they can be discharged and filled to obtain the finished product. The 3D printing photosensitive resin for jewelry casting of the present invention has the advantages of fully combustible performance, less residual ash, good jewelry casting effect, reduced polishing time, improved processing efficiency, and reduced processing cost.

Description

technical field [0001] The invention relates to a 3D printing material, in particular to a 3D printing photosensitive resin for jewelry casting. Background technique [0002] 3D printing technology is also called "additive manufacturing technology", which is a technology based on the principle of discrete and accumulation to realize manufacturing through the gradual accumulation of materials. In 3D printing, the computer divides the 3D model of the formed part into slices of a certain thickness, and finally superimposes to form a three-dimensional solid part. This manufacturing technology can realize the manufacture of complex structures that are difficult to process by traditional techniques without traditional tools or models, effectively simplifying the production process and shortening the production cycle. [0003] Light-curing 3D printing technology has the common advantages of shortening the product development cycle, reducing production costs, and realizing personal...
