Problems solved by technology

But at present, desktop-level 3D printers mainly use fused deposition technology, which can only print general filamentary plastics and other materials, but cannot print viscous liquids at room temperature, so there are many restrictions on the use of materials
However, professional-grade normal-temperature viscous liquid extrusion nozzles are expensive and have a small scope of application, which cannot meet the needs of mass consumption.

Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the present invention is described in detail as follows by specific example:

[0011] Such as figure 1 As shown, a normal temperature 3D printing nozzle includes a stepping motor 1, a screw 2, an upper mounting plate 3, a guide rod 4, a sleeve 5, a lower mounting plate 6, a connecting plate 7, a coupling 9, and a sliding bearing 10 , extruder syringe 11; the stepper motor 1 is connected to the lead screw 2 through a coupling 9, the sleeve 5 is fixed on the upper mounting plate 3 by threads, and is threadedly matched with the lead screw 2, so that the thread The bar 2 drives the upper mounting plate 3 to move up and down, the lower end of the guide rod 4 is fixed on the lower mounting plate 6, the sliding bearing 10 and the upper mounting plate 3 adopt an interference fit, and the guide rod 4 passes through the sliding bearing 10, so that The upper mounting plate 3 can slide up and down along the guide rod 4 , the extruder...

Abstract

The invention relates to a normal-temperature 3D printing spray nozzle. The normal-temperature 3D printing spray nozzle comprises a stepping motor, a screw rod, an upper installation plate, a guide rod, a sleeve, a lower installation plate, a connecting plate, a coupler, a sliding bearing and an extruder needle cylinder. The stepping motor is connected with the screw rod through the coupler. The sleeve is fixed to the upper installation plate through a thread and is in threaded fit with the screw rod so that the screw rod can drive the upper installation plate to vertically move. The lower end of the guide rod is fixed to the lower installation plate. The sliding bearing is in interference fit with the upper installation plate. The guide rod penetrates the sliding bearing so that the upper installation plate can slide vertically along the guide rod. The extruder needle cylinder is fixed to the lower installation plate through the connecting plate. The top end of a piston rod of the extruder needle cylinder is fixed to the upper installation plate. The normal-temperature 3D printing spray nozzle is integrated on a desktop-level 3D printer, the problem about normal-temperature slurry 3D printing can be solved, demounting and mounting are convenient, and high strength is achieved; and in practical use, stress is more reasonable, and operation can be more convenient.

Description

technical field [0001] The invention relates to a normal temperature 3D printing nozzle. Background technique [0002] In recent years, desktop-level 3D printers have a simple and beautiful structure. Compared with previous models, they have been greatly improved in terms of body rigidity, printing accuracy, and durability of structural parts. The nozzle adopts heat-dissipating treatment technology so that the material can be instantly condensed to achieve rapid prototyping. The XYZ axis positioning is more accurate, the printing edge is more tidy, the forming error is small, the operation is quite simple, in line with the humanized design concept, and the printing speed is fast. Great application. But at present, desktop-level 3D printers mainly use fused deposition technology, which can only print general filamentary plastics and other materials, but cannot print viscous liquids at room temperature, so there are many restrictions on the use of materials. However, profess...
