Embodiment 7

[0127] This embodiment provides a method for printing a 3D object, using any of the compositions described above to print a 3D object, figure 1 A flowchart of a 3D object printing method provided by an embodiment of the present invention, such as figure 1 shown, including the following steps:

[0128] S100. Obtain printing data of at least one layer of the 3D object;

[0129]First of all, the model data of the 3D object to be printed is sliced ​​and layered and data processed to obtain the layer printing data. It can be understood that the layer printing data is the data representing the cross section of the 3D object. After processing, at least one layer of printing data can be obtained, and all layers of printing data can be superimposed layer by layer to obtain a digital model of the 3D object. The present invention is not limited to the acquisition method of layer printing data, and any acquisition method of layer printing data in the process of 3D object printing in the...

Abstract

The invention provides a composition for 3D printing, a 3D printing method and a 3D printing device. The invention provides the composition for 3D printing on the first aspect. The composition is prepared from the following components in percentage by weight: 5 to 30 percent of ketoxime terminated diisocyanate, 5 to 40 percent of compound containing reactive hydrogen, 5 to 40 percent of first photocuring component, 20 to 80 percent of photocuring monomer, 0 to 30 percent of photocuring oligomer, 0.5 to 10 percent of photoinitiator, 0 to 1 percent of catalyst, 0.05 to 8 percent of additive, 0 to 15 percent of filler and 0 to 5 percent of coloring agent. The composition for 3D printing provided by the invention has adjustable viscosity, is suitable for ink-jet printing and / or three-dimensional photocuring molding technology, and has good thermal stability; and the 3D object printed by using the composition provided by the invention has good dimensional stability and mechanical properties.

Description

technical field [0001] The invention relates to a composition for 3D printing, a 3D printing method and a device, and relates to the technical field of 3D printing. Background technique [0002] Stereo-curing 3D printing technology mainly includes three-dimensional inkjet printing technology (3DP), stereolithography technology (SLA), digital light processing technology (DLP), continuous liquid surface manufacturing technology (CLIP), etc. This type of technology mainly uses liquid photosensitive resin As a raw material, under the condition of light irradiation, the photosensitive resin undergoes a polymerization reaction and is rapidly cured to form a 3D object. Light-curing 3D printing technology has the characteristics of high molding precision, high printing efficiency, and mature technology. It is one of the earliest developed and commercialized 3D printing technologies. [0003] With the continuous development of light-curing 3D printing equipment and technology, raw m...
