Problems solved by technology

[0013] According to the present invention, it is possible to ensure the height control of the slurry in the slurry tank and reduce the coating steps of the slurry surface layer after photocuring, shorten the printing time, and overcome the liquid level fluctuation and uneven coating caused by the traditional scraper-type material spreading structure. Disadvantages, reduce the impact of slurry fluidity on the process of filling slurry, improve work efficiency and print layer thickness accuracy

Embodiment ）

[0054] Hereinafter, the process flow of the sealed pressurized slurry tank device in working state according to the above-mentioned embodiments of the present invention will be described in detail in conjunction with specific examples. Specifically, in this embodiment, the booster pump 19 can be, for example, a peristaltic pump or a micropump that can withstand a pressure of 0-2 MPa, a flow rate of 0.001-400 ml / min, and a rotational speed of 0.1-200 rpm. The main slurry tank 9 can be made of stainless steel, for example, and has a size of L150×W150×H150mm˜L800×W800×H600mm. The transparent sealing plate 7 can be, for example, an acrylic plate with high light transmittance. The release layer 8 can be, for example, a release film with high light transmittance. The LED light source 1 may be, for example, an ultraviolet LED light source with a rated power of 20W and a wavelength of 365nm. The DMD device 2 can be, for example, a product of Texas Instruments.

Abstract

The invention relates to a sealing booster-type slurry pool device for an overhead light source 3D printer. The sealing booster-type slurry pool device comprises a main slurry pool, a light source mechanism, a transparent sealing mechanism, a lifting mechanism, a sample platform and a booster filling mechanism, wherein the main slurry pool is filled with liquid slurry for light solidification, thelight source mechanism is installed above the device, the transparent sealing mechanism is installed on the top of the main slurry pool, the lifting mechanism is installed in the main slurry pool, the sample platform is installed on the lifting mechanism, and the booster filling mechanism is connected with the main slurry pool. According to the sealing booster-type slurry pool device, the heightcontrol over slurry in the slurry pool can be guaranteed, the coating step of the surface layer of the slurry after light solidification is omitted, the printing time is shortened, the defects of level fluctuation and uniformity in coating of a traditional scraper type spreading structure are overcome, the influence of the slurry flowability on a slurry filling process is reduced, the working efficiency is improved, and the printed layer thickness accuracy is increased.

Description

technical field [0001] The present invention relates to the field of 3D printing, in particular to the photocuring rapid prototyping process in the technical field of 3D rapid prototyping, and in particular to a sealed pressurized slurry pool device for an upper-mounted light source 3D printer. Background technique [0002] 3D printing technology is an additive manufacturing technology that is diametrically opposed to traditional material processing methods. Based on three-dimensional digital model design, through software layered discrete and numerical control molding systems, materials such as ceramic powder, resin, and metal powder are layered. Processing, stacking and bonding, and finally superimposed molding to create a three-dimensional solid. Compared with traditional manufacturing methods, 3D printing technology saves raw materials, performs rapid manufacturing of complex structures, shortens the research and development cycle, and is more suitable for the production...
