Problems solved by technology

However, when this solution further increases the printing speed, it is easy to cause cross-color problems between the boundaries on the model surface
The main reason for this problem is that in the fast printing state, when the coloring ink is continuously sprayed to the aperture after the coloring contour cutting, it tends to permeate irregularly to the lower paper surface, and it solidifies on the paper surface when the boundary waste is removed after molding, resulting in The color reproduction effect of the final color 3D solid printing is not ideal and is not accepted by customers.

Abstract

The invention provides an optimization method for color reproduction of paper-based full-color 3D printing. According to the optimization method, a step-by-step cutting and jet printing integrated control strategy is adopted, and all the function states and positions of a laser beam emitter for cutting and an ink nozzle for coloring mounted on a cutting and jet integrated unit module are adjustedthrough model layering information. According to the method, the operation steps and the parameter setting of a step-by-step cutting method and a step-by-step coloring method of a pre-gluing printingpaper coloring profile are proposed, the higher printing speed can maintained, the problem of cross color of the ink at the bottom layer paper surface boundary in the printing process can be solved, the application of paper-based full-color 3D printing technology in high-precision and high-speed color reproduction is greatly satisfied, and the industrialization in the field of cultural creation ispromoted.

Description

technical field [0001] The invention relates to an optimization method for color reproduction of paper-based full-color 3D printing, which belongs to the technical field of 3D printing. Background technique [0002] As an innovative digital manufacturing technology, 3D printing has been applied to personalized product customization in various industries. With the optimization of color 3D printing process, customized products are more realistic and low-cost. Common color 3D printing processes mainly include paper-based full-color 3D printing process, powder-based full-color 3D printing process, plastic-based full-color 3D printing process, etc. Among them, paper-based 3D printing process is required to be accurate because of its environmental protection and low cost of printing consumables. The cultural and creative field of color reproduction is more widely used. [0003] The paper-based full-color 3D printing process was launched by the IRIS series of 3D printers first rel...
