Embodiment 1

[0064] Embodiment 1: A DLP color three-dimensional printing device based on down-illuminated molding performs a color printing process:

[0065] First establish a computer model of a three-dimensional object, slice and layer it after generating the support, and obtain the shape information and surface color information of each layer; associate the obtained information data with the automatic control system; the forming plate 1 rises to the highest (or suitable ) position, the nozzle group 4 slides into the forming working pool 2, and the automatic control system controls the moving mechanism 5 to drive the nozzle group 4 to move in three displacement directions of freedom, front and rear, left and right, and up and down, and spray out the base layer of the three-dimensional model at the same time. After the base layer is sprayed, the nozzle group 4 returns to its position, and the forming plate 1 is lowered to connect with the forming working pool 2, and then the DLP projection...

Abstract

The invention discloses a three-dimensional color printing device and method. The three-dimensional color printing device comprises a print area, a feeding system, a nozzle group, a moving mechanism and an automatic control system, wherein the print area is provided with a forming plate and a forming work pool, and the forming plate is provided with a lifting mechanism which is used for drawing a workpiece curing layer; the feeding system comprises a support material feeding box and a solid material feeding box and is used for supplying print raw materials for the nozzle group; the nozzle group comprises at least one solid material nozzle and a support material nozzle, the solid material nozzle is connected with the solid material feeding box of the feeding system through a premixer, and the support material nozzle is connected with the support material feeding box of the feeding system; andthe moving mechanism is provided with motors and guide posts / rods on the X-axis direction, the Y-axis direction and the Z-axis direction and is used for driving the nozzle group for performing mobile printing on the three-dimensional direction. The three-dimensional color printing device has the characteristics of being high in print accuracy and smooth and clean in surface of formed products and can realize color printing and printing of different photosensitive materials.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing and molding, in particular to a color three-dimensional printing device and method. Background technique [0002] Three-dimensional (3D) printing technology is an important part of the additive manufacturing industry. Based on digital model files, it uses bondable materials such as powdered metal, resin, wax or plastic to construct objects by printing layer by layer. , is an integrated advanced manufacturing technology. [0003] At present, the more mainstream 3D printing technologies include Fused Deposition Modeling (Fused Deposition Modeling, FDM), Stereo Lithography Apparatus (SLA), Selective Laser Sintering (Selective Laser Sintering, SLS), 3D Printing (Three Dimensional Printing, 3DP), digital light Processing technology (DigitalLightProcession, DLP), etc. [0004] The FDM printer heats and melts the filamentous hot-melt material, extrudes it through the nozzle and depos...
