Embodiment Construction

[0118] [best practice]

[0119] Below in conjunction with accompanying drawing, the present invention will be further described with regard to preferred embodiment:

[0120] Such as figure 1 Shown:

[0121] The color nozzle (1) used for printing color ink is installed on a mechanism that can perform two-dimensional plane motion and a vertical parallel axis motion synthesis. They are composed of a moving rotation axis A (4) and a fixed rotation axis (6). The planar motion system; the ink storage box (3) transmits the color (UV) ink to the color nozzle (1) through the ink delivery pipe (2);

[0122] Driven by the motor, the lifting platform bracket (19) supports the lifting platform (14) and carries the formed object (12) down to the height of one printing layer each time, forming a vertical direction of the lifting movement direction (11); In order to ensure the smoothness of the resin liquid level, the resin scraper (15) moves along the horizontal direction shown in the mov...

Abstract

The invention discloses an SLA full-color 3D printing method and device based on an inkjet color interlayer, and belongs to the technical field of machinery and photoelectricity. The hardware and software supporting the method comprise: a motion mechanical system, a control system, an ink supply system, a projection light system, a photocurable material and layering software. The method comprisesthe steps of performing inkjet on a curing cut layer of the SLA, printing and curing as required to form a color ink interlayer, lowering a carrying platform and submerging the color ink interlayer toform a new curing cut layer of the SLA, curing the cut layer as required, circularly performing the operations, enabling the cured transparent resin to wrap the ink interlayer, and finally forming areal color thin layer on the shallow surface of a printed object. Thus, high-precision printing of a color three-dimensional printed product is achieved.

Description

[0001] [Field] [0002] The invention belongs to the field of mechanical-optical technology. To be precise, it is a full-color 3D printing method and device for forming a colored interlayer by means of inkjet printing to generate a colored thin layer, and then wrapping the thin layer by SLA. [Background technique] [0003] (Laser galvanometer scanning and solidification) SLA development history [0004] More than 30 years ago, the day when 3D printing came out, it started from the photo-curing technology SLA stereolithography technology. The first rapid prototyping equipment in 1984 used the light-curing three-dimensional modeling process. Among the current rapid prototyping equipment, SLA is the most in-depth research and the most widely used. [0005] In 1986, Dr. Charles W Hull of the United States proposed the concept of using laser light to irradiate the surface of photosensitive resin and curing to make three-dimensional objects in one of his papers. Later, Charles WH...
