Problems solved by technology

[0003] The old grating material production method usually requires a plastic plate machine to heat the plastic granule material and then press it through the corresponding grating roller mold. This method needs to be equipped with large-scale equipment, which is complicated and expensive, and the production needs to be expensive. great manpower and material resources

Abstract

The invention discloses a device and a method for 3D printing of size-variable three-dimensional optical gratings. The device comprises a first spraying nozzle, a second spraying nozzle, a base plate, a Y-directional sliding plate, a base plate, Y-directional guide rails, an X-directional transverse beam, Z-direction stand columns and a control module; the two Y-directional guide rails are symmetrically installed on the base plate in parallel, and the Y-directional sliding plate is installed on the guide rails in a manner of being capable of sliding in the Y-axis direction; the two Z-direction stand columns are symmetrically installed at one end of the base plate in parallel, and the X-directional transverse beam is installed on the Z-direction stand columns in the manner of being capable of sliding in the Z-axis direction; the first spraying nozzle and the second spraying nozzle are installed on the X-directional transverse beam in the manner of being capable of sliding in the X-axis direction; the base plate is rotationally installed on the Y-directional sliding plate; and the control module is used for controlling the first spraying nozzle, the second spraying nozzle, the X-directional transverse beam, the Y-directional sliding plate and the base plate to move. By means of the device and the method, the preparing time of the three-dimensional optical gratings can be greatly shortened, the multiple optical gratings in different sizes can be molded at a time, the requirement of multiple and different applications can be met on both the plane and the curve face, and cost is greatly saved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a device and method for 3D printing a variable-size three-dimensional grating. Background technique [0002] Lenticular is a special film that combines digital graphics and traditional printing technology so that the human eye can clearly and clearly feel the three-dimensional effect by placing the original two-dimensional picture directly in front of the eyes without any tools. This is another major step toward the three-dimensional world after the black-and-white picture and then the color picture. As a kind of grating, three-dimensional lenticular is widely used in advertising, wedding photography, indoor and outdoor decoration, printing, etc. It has a three-dimensional effect, produces magic changes through angles or swings, animation, and scaling to make the image column beautiful. It has become the first choice for office stationery and home decoration user...
