Problems solved by technology

The current common method is: use 3D printing equipment to make dental molds, and the dental molds are cleaned and dried with alcohol or isopropanol and then post-cured to complete the processing of dental molds. However, the cleaning process of dental molds consumes a lot of alcohol or isopropanol. Generates process risks, contamination and large amounts of waste

preparation example Construction

[0037] A water-washable DLP3D printing dental mold resin formulation, the preparation method of which specifically includes the following steps:

[0038] Step 1: Add water-based urethane acrylate oligomer, acrylate monomer, surfactant and photoinitiator into the beaker, mix and stir evenly;

[0039] Step 2: ultrasonically disperse for 5 minutes after stirring evenly;

[0040] Step 3: Add the ultrasonically processed product to the LCD 3D printer to print the mechanical spline;

[0041] Step 4: Preliminarily clean the surface of the printed mechanical spline with water;

[0042] Step 5: ultrasonically treat the cleaned mechanical splines in water for 5 minutes;

[0043] Step 6: The mechanical spline is taken out and cured after ultrasonic treatment in water;

[0044] Step 7: The cured mechanical splines are used for the testing of mechanical properties and thermal properties.

Abstract

The invention provides a washable DLP 3D printing dental cast resin, which is characterized by comprising a waterborne polyurethane acrylate oligomer, an acrylate monomer, a photoinitiator and a surfactant, the preparation method comprises the following steps: uniformly mixing and stirring in a beaker, and performing ultrasonic dispersion treatment; adding a product subjected to ultrasonic treatment into an LCD3D printer to print a mechanical spline, cleaning the surface with clear water, performing ultrasonic treatment in water, taking out and curing; the cured mechanical sample strip is used for testing mechanical properties and thermal properties; through a specific formula, the step of cleaning and drying the dental cast by using alcohol or isopropanol before curing the dental cast is changed into the step of replacing the step by using clear water, so that the risk and pollution in the process of manufacturing the dental cast are effectively solved, the problem that a large amount of waste liquid is generated in the process of manufacturing the dental cast is solved, and the cost is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing technology, in particular to a water-washable DLP 3D printing dental mold resin. Background technique [0002] 3D printing technology, also known as rapid prototyping technology, is a technology that constructs objects by layer-by-layer printing using bondable materials such as powdered metal or plastic based on digital model files. 3D printing technology is widely used in the field of dental invisible orthodontics. At present, the common method is: use 3D printing equipment to make dental molds. The dental molds are cleaned and dried with alcohol or isopropyl alcohol and then post-cured to complete the processing of dental molds. However, the cleaning process of dental molds consumes a lot of alcohol or isopropyl alcohol. This creates process risks, contamination and a lot of waste. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes a wa...
