3D (three-dimensional) printer powder pre-production device

Abstract

The invention discloses a 3D (three-dimensional) printer powder pre-production device which comprises a powder cylinder, a powder arm and a powder-spraying head. The powder cylinder is arranged on a shaping chamber, the powder arm is arranged in the shaping chamber, and the powder-spraying head which is of a disc structure is arranged on the powder arm. The powder-spraying head is connected with the powder cylinder through a round hose, and is provided with a valve with turning on and off controlled by a motor. A precise servo motor system is adopted to perform two-dimensional precise precast materials upon the powder-spraying head, the powder arm can be controlled to move leftward and rightward precisely, the powder-spraying head can simultaneously and precisely move back and forth on the powder arm, a computer identifies materials required by parts, and a control system controls the disc-structured powder-spraying head and a powder-feeding cylinder to provide powder to a shaping cylinder through the servo motor system according to contour information of slices, so that 3D printing manufacturing of the composite material parts can be realized. The 3D printer powder pre-production device is simple in structure, high in operability and capable of realizing 3D printing of composite materials, the parts of complicated internal structures can be manufactured, and production efficiency of a printer can be improved.

Description

technical field [0001] The invention relates to a powder spraying component of a 3D printer, in particular to a powder prefabrication device for a 3D printer. Background technique [0002] Compared with traditional machining such as turning, milling and planing, metal 3D printing, as an additive manufacturing method (Addictive Manufacturing), can manufacture various complex structures and give full play to the efficiency of materials. It is one of the main methods of green manufacturing in the future. Its advantage lies in expanding the space for product creativity and innovation. Designers are no longer constrained by traditional craftsmanship and manufacturing resources, and reduce product R&D innovation costs, shorten R&D cycles, and enhance process manufacturing capabilities. Therefore, in aerospace, biomedical, industrial molds, automobiles, etc. Manufacturing and other industrial fields have unique application prospects, especially in small-batch and multi-variety aero...
