Frequency-division multiplexing (FDM)-based three-dimensional (3D) printer

Abstract

The invention discloses a frequency-division multiplexing (FDM)-based three-dimensional (3D) printer, comprising a frame, a base, an X-axis mobile system, a Z-axis mobile system and a printing device, wherein the printing device is connected with the X-axis mobile system; the X-axis mobile system is connected with the Z-axis mobile system; the Z-axis mobile system is connected with a guide rail of an upright post; a power supply and a controller are arranged on the base; the controller is connected with the Z-axis mobile system; the Z-axis mobile system comprises a third numerical control motor, a left screw and a right screw, a Z-axis fixed base and a limit switch; the left screw and the right screw are respectively arranged at the outer sides of a left upright post and a right upright post; the third numerical control motor is connected with the lower ends of the screws; the screws are connected with screw nuts; the screw nuts are connected with the Z-axis fixed base; the Z-axis fixed base is connected with the X-axis mobile system; a fixed base through hole is formed in the Z-axis fixed base; the left upright post and the right upright post pass through the fixed base through hole; the bearing is matched with the guide rail of the upright post. Thus, the FDM-based 3D printer is simple and compact in structure, small in volume and low in manufacturing cost.

Description

Technical field [0001] The present invention relates to the technical field of 3D printers, in particular to a new type of 3D printer based on FDM. Background technique [0002] 3D printers are an emerging technology development industry with more and more extensive uses and huge market demand. At the same time, the number of 3D DIYers is increasing. However, because of the high cost and low efficiency of using 3D printers to print parts The structure of the printer is relatively complicated, the volume is relatively large, the structure is not compact, the purchase and use and maintenance costs are relatively high, which limits the market and scale of consumers. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art and provide a new type of 3D printer based on FDM; the present invention has a simple structure, compact structure, small volume, low production cost, and meets the growing consumer demand for 3...
