Catalytic curing type 3D printing technology and printer

Abstract

The invention relates to a catalytic curing type 3D printing technology. The catalytic curing type 3D printing technology comprises the specific steps that (1), a catalytic curing molding 3D printer is started; (2), data models are input to the 3D printer; (3), a functional area and a non-functional area are divided; (4), main curing agent materials are used for firstly describing contours which are not molded through curing; (5), a catalyst accelerator is used for accelerating molding of a curing agent; and (6), the step (4) and the step (5) are repeated until all the data models are printed. The catalytic curing type 3D printing technology can be used for carrying out multifunctional, multi-material, high-precision and multi-color 3D printing; the models printed through the technology are high in density and not prone to damaging, have no layering and are good in overall effect.

Description

technical field [0001] The invention belongs to 3D printing technology and relates to a 3D printer, in particular to a catalytic solidification type 3D printing technology and a printer. Background technique [0002] At present, rapid prototyping technologies on the market are divided into 3DP technology, FDM fusion lamination molding technology, SLA stereolithography technology, SLS selective laser sintering technology, DLP laser forming technology and UV ultraviolet forming technology. [0003] 3DP technology: 3D printers using 3DP technology use standard inkjet printing technology to create components layer by layer by printing cross-sectional data by laying liquid joints on a thin layer of powder to create a three-dimensional solid model. The sample model printed by technology has the same color as the actual product, and the color analysis results can also be directly depicted on the model. The information conveyed by the model sample is relatively large, but the materi...

Problems solved by technology

[0003] 3DP technology: 3D printers using 3DP technology use standard inkjet printing technology to create components layer by layer by laying liquid joints on a thin layer of powder to create a three-dimensional solid model by printing cross-sectional data. The sample model printed by technology has the same color as the actual product, and the color analysis results can also be directly depicted on the model. The information transmitted by the model sample is relatively large, but the material is relatively single, and multiple materials cannot be applied

This technology has high molding precision and can rival injection-molded durable plastic parts in terms of material properties, details, and surface finish, but the objects printed by the above 5 methods only have a small number of colors, and the colors are poor
