Problems solved by technology

The advantages of light-curing forming materials are fast curing speed, high material utilization rate, low environmental pollution and very short forming cycle, etc., but there are still many shortcomings that need further research, such as poor transparency, poor surface quality, hardness Low, low toughness, poor heat resistance, curing of these defects prevents the formed part from being directly used as a functional part and cured, greatly reducing its application range
[0003] CN105949418A discloses a 3D printing resin for aluminum casting and its production method, which overcomes the shortcomings of the existing traditional resin for aluminum casting in terms of production cost, work efficiency and environmental protection, and has stable chemical properties and is suitable for 3D printing. Printing technology, low production cost, easy operation, and environmental friendliness, but there are problems with the tensile strength, heat resistance and bending resistance of the cured parts of 3D printing materials after printing

Abstract

A production process of 3D printing resin is disclosed. Through addition of graphene oxide, the photocuring rate of a composite material is increased, the volume shrinkage rate of photosensitive resinis reduced, the curing rate of the composite material firstly increases and then decreases along with the increase of the content of the graphene oxide, tensile and bending properties of the photosensitive resin can be improved through adding the graphene oxide, and tensile strength and bending strength firstly increase and then gradually decrease along with the increase of the content of the graphene oxide. The process has advantages of capability of allowing tensile strength, heat resistance and bending resistance of a cured product of the printed 3D printing material to be high, and a widemarket prospect.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a production process of 3D printing resin. Background technique [0002] The light-curing resin is cured, similar to paint, and after curing, it is similar to engineering plastics. The performance of the light-curing molding material directly affects the quality and cost of the molding, and the precision, mechanical properties and deformation of the molding are closely related to the molding material. The advantages of light-curing forming materials are fast curing speed, high material utilization rate, low environmental pollution and very short forming cycle, etc., but there are still many shortcomings that need further research, such as poor transparency, poor surface quality, hardness Low, low toughness, poor heat resistance, these defect curing make the formed part can not be used directly as a functional part to cure, so that its application range is greatly reduced.
