Naked-eye three-dimensional printing product and manufacturing method thereof

Abstract

The invention provides a naked-eye three-dimensional printing product and a manufacturing method thereof and belongs to the three-dimensional printing technical field. The naked-eye three-dimensional printing product comprises a transparent sheet; the front surface of the transparent sheet is provided with a microlens array layer; the back surface of the transparent sheet is provided with a micro graphic-text set array layer and a macro pattern layer; the back layer of the macro pattern layer is provided with a protective layer; the microlens array layer comprises a plurality of arrayed segment-shaped microlenses; the micro graphic-text set array layer includes a plurality of arrayed micro graphic-text sets; the microlens array and the micro graphic-text set array are both a rectangular array; an included angle of the extension line of each row of graphic-text sets in the micro graphic-text set array layer and the length direction of the micro graphic-text set array layer is 45 degrees; and an included angle of the extension line of each row of microlenses in the microlens array layer and the length direction of the microlens array ranges from 0 degree to 10 degrees. The naked-eye three-dimensional printing product is used for providing a naked-eye visibly three-dimensional image.

Description

Technical field [0001] The present invention relates to the technical field of three-dimensional printed matter, in particular to a naked-eye three-dimensional printed matter and a manufacturing method thereof. Background technique [0002] Because there is a certain distance between human eyes, a certain angle is formed between the left and right eyes and the object, resulting in subtle differences in the objects seen by the left and right eyes, resulting in parallax. This parallax is reflected in the brain to produce a three-dimensional sense of space. Grating three-dimensional printing uses the optical effect of the grating to make the left and right eyes see two different viewpoint images of the same object, which are then merged in the brain to produce a depth image with a parallax stereo effect. [0003] The stereoscopic display technology of microlens array grating was first proposed in 1908, but it was limited to the extremely high precision requirements of microlens array ...
