Embodiment 1

[0033] see figure 1 , a kind of projective mosaic type 3D printing method, comprises the following steps:

[0034] Step1: Slice the 3D model to be printed, and slice the slices of each layer according to the size, length and width of the 3D model, forming several rectangular arrays of the same size and arranged in order;

[0035] Step2: Obtain the image data of the 3D model to be printed on each layer;

[0036] Step3: Arrange the rectangles according to the order of the rectangle array in the set time period, and expose each rectangle in the rectangle array one by one until all the images of the rectangles in the layer are exposed.

[0037] In an embodiment, the above method further includes Step4: after the exposure of the image on one layer is completed, the image exposure plane drops to the printing height of the next layer to realize the exposure of the image on the next layer, and print layer by layer until the product is printed.

[0038] In the embodiment, the specifi...

Embodiment 2

[0051] The difference from Embodiment 1 is that the projection device 4 can also be placed above the resin tank 3 to form a top projection type.

Abstract

The invention discloses a projection combining type 3D printing method and a 3D printing device. The 3D printing method comprises the following steps that a to-be-printed 3D model is subjected to slicing treatment firstly, then each layer is sliced according to equal proportions based on the size, the length and the width of the 3D model, and a plurality of rectangular arrays with the same size and arranged in sequence are formed; image data of all layers of the to-be-printed 3D model are obtained; rectangles are arranged according to the sequence of the rectangular arrays in a set time period, and the rectangles of the rectangular arrays are gradually exposed until images of all the rectangles of the layer are exposed; and after the images located on the layer are exposed, an image exposing plane declines to the printing height of a next layer, images of the next layer are exposed, and layer-by-layer printing is performed until product printing is completed. By means of the projectioncombining type 3D printing method and the 3D printing device, the problem that the size of a product printed by 3D printing equipment adopting a digital light processing technology is not big enoughis solved.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, in particular to a projection-joining 3D printing method and a 3D printing device. Background technique [0002] 3D printing technology is a kind of additive manufacturing technology. By layering the three-dimensional model, the image information of each layer is obtained, and then the printing head or light source is used to print the image data information of each layer. After repeated iterations, an entity is formed. 3D model. [0003] DLP is digital light processing technology. At present, a single DLP projector is placed in the lower part of the resin tank for light projection, irradiating the photosensitive material, so that the photosensitive material is solidified, so as to realize layer-by-layer superposition molding and complete the printing of the product. DLP light curing technology uses a surface light source, so the printing speed is fast, and products can be manufactur...
