FDM (fused deposition modeling) technology-based 3D (three-dimensional) printer

Abstract

The invention discloses an FDM (fused deposition modeling) technology-based 3D (three-dimensional) printer. The FDM technology-based 3D printer comprises a rack, a base, an X-axis movement system, a Y-axis movement system, a Z-axis movement system and a printing device, wherein the rack comprises a left upright column, a right upright column and a lower connecting plate; the printing device is connected with the X-axis movement system; the X-axis movement system is connected with the Z-axis movement system; the Z-axis movement system comprises a left screw rod and a right screw rod; screw rod nuts are arranged on the left screw rod and the right screw rod; a power supply and a controller are arranged at the bottom of the base; the controller is connected with the X-axis movement system and the printing device; the X-axis movement system comprises a first numerical control motor, X-axis movement guide rails and a first limiting switch; the X-axis movement guide rails are respectively connected with Z-axis fixed seats and are connected with supporting arms of the printing device; the first limiting switch is connected with the lower parts of the Z-axis fixed seats, is matched with a left supporting arm of the printing device and is connected with the controller. The FDM technology-based 3D printer is simple and compact in structure, small in size and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a 3D printer with FDM technology. 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 FDM technology 3D printer to solve the above-mentioned problems in the prior art; the present invention is simple and compact in structure, small in size and low in production cost, and satisfies the increasing consumpti...
