A 405nm dlp printing process of different interlayer colors

Abstract

The invention relates to a 405nm DLP process for printing different interlayer colors, which belongs to the technical field of 3D printing, and specifically includes creating a product model by using drawing software, and generating a .stl data model file; importing the .stl data model file into Dolphin Studio slicing software, According to the set thickness of each layer, slice the data model and generate a .3dp printing trajectory file; import the .3dp printing trajectory file into the DLP printer, and add photosensitive resin to the resin tank of the DLP printer to set the printing parameters , start printing; during the printing process, add different pigments intermittently and quantitatively through the pigment adding mixing and stirring device, and stir evenly, adjust the color of the photosensitive resin to the set color, and then continue printing; finally print products with different interlayer colors ; The present invention is simple to operate and easy to use, and can print different colors according to needs to meet individual needs.

Description

technical field [0001] The invention relates to a 405nm DLP printing process for different interlayer colors, belonging to the technical field of 3D printing. Background technique [0002] 3D printing, also known as additive manufacturing, is a new manufacturing technology that accumulates materials layer by layer to produce physical objects based on digital models. 3D printing equipment can process products with personalized and customized special structures. [0003] 3D printing photo-curing molding technology has higher printing accuracy and shorter printing time, so 3D printing photo-curing molding technology is developing rapidly. The principle of DLP (Digital Light Processing, digital light processing) rapid prototyping technology is to use slicing software to cut the three-dimensional model of the object into thin slices, transform the three-dimensional object into a two-dimensional layer, and then use the digital light source to make the photosensitive resin layer b...

Problems solved by technology

[0005] At present, DLP printing can only print a single color product, and the performance of the product cannot be changed, which limits the application and promotion of DLP printing equipment

When people require that the color (or performance) of the bottom of the product is different from the color (or performance) of other parts, especially in the field of medical dentistry, it is required that the part of the bottom of the product that is in contact with the root of the tooth has a lower hardness and a softer material, and the hardness of the cusp is higher. , DLP printers can't do it, and can't meet people's needs for individual requirements such as different colors and performances for different parts, which limits the application of DLP printers
