Portable 3d printer based on fdm technology

Abstract

The invention discloses a portable 3D printer based on an FDM (frequency-division multiplexing) technology. The portable 3D printer comprises a printing device, wherein the printing device comprises an extrusion printing head, a connecting frame and a feeding mechanism; the extrusion printing head is connected with the lower part of the supporting seat; the extrusion printing head comprises a printing head and a printing consumable material guide sleeve; the upper part of the printing head is connected with a heater; the heater is provided with a temperature sensor; the temperature sensor is connected with a controller; a heat insulation gasket is arranged at the upper part of the heater; the upper part of the heat insulation gasket is connected with a heat insulation sleeve; the upper part of the heat insulation sleeve is connected with a heat insulation plate; the heat insulation plate is connected with a printing head connecting plate at the upper part; the printing head connecting plate is connected with the lower part of the connecting frame; a printing head cavity body for containing a molten printing consumable material body is formed in the printing head; the heater, the heat insulation sleeve and the printing head connecting plate are provided with axial through holes; the axial through hole of the heater is communicated with the printing head cavity body; the printing consumable material guide sleeve is connected with the heat insulation sleeve. The small 3D printer has the advantages that the structure is good in heat dissipation property; the working reliability of the connecting frame and the parts mounted on the connecting frame is improved; the service life of the connecting frame and the parts mounted on the connecting frame is prolonged.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a portable 3D printer based on 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.
