Embodiment Construction

[0023] Hereinafter, the laser line array 3D printing device and the forming method thereof of the present invention will be further described in detail with reference to the drawings and specific embodiments of the present invention.

[0024] The invention can theoretically realize the unlimited expansion of the processing breadth. Limited by the experimental conditions, the laser diode line array with a length of about 200mm is prepared by using 1000 laser diodes LD with a distance between the diodes of 0.1mm. The 1mm diameter of the laser diode chip lamp bead not only breaks through the limitation of large-format processing, but also ensures the molding accuracy. In addition, there are many kinds of laser diode power and wavelength, according to the used power and wavelength combined with the molding material, it can meet different molding requirements.

[0025] The laser line array 3D printing equipment includes a computer controller 60, a forming pallet 10, a storage box 30, a ...

Abstract

The invention discloses laser linear array type 3D printing equipment which comprises a computer controller, a molding supporting plate, a storage box, a laser irradiator and a scraper, wherein a lifting mechanism is arranged below the molding supporting plate; the molding supporting plate and the lifting mechanism are integrally arranged in the storage box; a large quantity of to-be-used materials are arranged in the storage box; the liftable scraper and the laser irradiator are arranged above the molding supporting plate; and multiple laser diodes are arranged on the laser irradiator in a linear array manner. According to the equipment disclosed by the invention, the laser linear array irradiator is adopted based on a SLA technology, a large-scale image is scanned and molded from a linear mode to a surface mode, a large-scale large-size product can be efficiently and accurately molded and manufactured, the molding rate is increased, and the time consumed in the manufacturing process is reduced.

Description

【Technical Field】 [0001] The present invention designs a 3D molding technology field, and particularly relates to a rapid 3D molding technology using laser diode line array arrangement. 【Background technique】 [0002] 3D printing technology, also known as additive manufacturing technology, realizes the printing of three-dimensional models through the process of automatic numerical control layer-by-layer material accumulation. Compared with traditional processing technology, 3D printing technology does not need to make additional molds and directly process finished products. Moreover, it can overcome the special structural obstacles that cannot be achieved by traditional mechanical processing, can realize the simplified production of any complex structural parts, and can automatically, directly and accurately transform the design ideas from CAD models into models or devices with certain functions. [0003] At present, 3D printing technology can be divided into: fused deposition tec...
