A desktop 3D printing device

Abstract

The invention relates to a desktop 3D-printing forming device comprising a base plate, a machine frame and connection blocks. The machine frame is a bottomless rectangular frame and is fixed on the base plate; vertex angles of the machine frame are provided with the connection blocks, adjacent connection blocks are connected with Y-direction guide rails, and transmission systems are arranged above the connection blocks and between adjacent connection blocks; the end of one transmission system at one side is connected to one end of a step motor output shaft, and the other end of the step motor output shaft is connected to the end of the other transmission system at the other side; the Y-direction guide rails which are on two opposite sides are provided with slide blocks, and the top end of the Y-direction guide rails which are on two opposite sides are connected with the transmission systems; X-direction guide rails are arranged between the slide blocks which are two opposite sides, and printing systems are arranged between the X-direction guide rails; the printing systems are connected with wire feeders; the base plate is vertically provided with a linear motor, and output shaft is a Z-direction guide rail; the Z-direction guide rail is connected with one end of an installing beam; and a heating work plate is arranged on the top of another end of the installing beam, and is under the printing systems. Moulding precision is high, processing speed is fast, technology is simple, cost is low, and the desktop 3D-printing forming device can be widely applied in household and the field of teaching.

Description

technical field [0001] The invention relates to the technical field of three-dimensional additive manufacturing, in particular to a desktop 3D printing forming device. Background technique [0002] Rapid prototyping (RP), also known as rapid prototyping technology, is an advanced manufacturing technology developed in recent years. Rapid prototyping technology originated in the United States in the 1980s, and soon developed to Japan and Europe. It is a major breakthrough in the field of manufacturing technology in recent years. Rapid prototyping is a digital forming technology based on the idea of ​​discrete accumulation forming, which automatically and quickly materializes design ideas into prototypes with certain structures and functions or directly manufactures parts, so that product designs can be quickly evaluated and modified, and enterprises can be improved. competitiveness. [0003] RP integrates advanced technologies such as CAD, CAM, CNC, precision servo drive, op...
