FDM (frequency-division multiplexing) 3D (three dimensional) printer

Abstract

The invention discloses an FDM (frequency-division multiplexing) 3D (three dimensional) printer. The 3D printer comprises a rack and an X-axis moving system, wherein a controller is connected with the X-axis moving system and a printing device; the X-axis moving system comprises a first numerical control motor and a horizontal X-axis moving guide rail, the horizontal X-axis moving guide rail is connected with a left-side support arm and a right-side support arm, the first numerical control motor is connected with a first synchronous toothed belt, the first synchronous toothed belt is a long-strip belt, one end of the long-strip belt is connected with the left-side support arm, the other end of the long-strip belt is connected with the right-side support arm, a first groove is formed in the left-side support arm, a second groove is formed in the right-side support arm, the left end of the first synchronous toothed belt is meshed and locked with the first groove, the right end of the first synchronous toothed belt is bent inwards, tooth grooves on two sides of a bent part of the first synchronous toothed belt are correspondingly matched with a tooth top to form a gear belt overlap region, and the gear belt overlap region is matched and locked with the second groove. The FDM 3D printer is simple in structure and small in volume and low in cost.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an FDM 3D printer. Background technique [0002] 3D printer is an emerging technology development industry with more and more extensive uses and huge market demand. At the same time, the number of 3D DIY people is increasing. However, due to the high cost and low efficiency of printing spare parts with 3D printers, and the 3D The structure of the printer is relatively complex, the volume is relatively large, the structure is not compact, and the cost of purchase, use and maintenance is relatively high, which limits the market and scale of use by consumers. Contents of the invention [0003] The purpose of the present invention is to provide a kind of FDM 3D printer in order to solve the above-mentioned problems existing in the prior art; Consumer demand for printers. [0004] The technical scheme that the present invention solves technical problem is: [0005] A 3D print...
