Three-dimensional waxing printer and using method thereof

Abstract

The invention discloses a three-dimensional waxing printer and a using method thereof. The printer comprises a rack, wherein pairwise-opposite X-direction and Y-direction moving shafts are arranged at the upper layer of the rack; the X-direction and Y-direction moving shafts are respectively provided with a slider and are respectively provided with X-direction and Y-direction guide rails by the sliders; a printer nozzle connected with a material storage tank at the lower layer of the rack through a material delivery pipe is arranged at the overlapped part of the X-direction and Y-direction guide rails; the material storage tank is connected with a peristaltic pump; a pair of Z-direction moving screw rods, which is driven by a Z-direction moving control motor and forms a moving pair together with a workbench, is arranged between the upper layer and the lower layer of the rack. The method comprises the following steps: assembling the printer, mixing raw materials, setting the transfer capacity of the raw materials, adjusting the height of the workbench, and printing. Multiple defects of the prior art are overcome; compared with the existing printers, the three-dimensional waxing printer is simple in structure and convenient to manufacture, raw materials can be supplied continuously, wax can be conveyed uniformly, the processing time is short, the processing cost is low, and the printing effect and the processing precision are good.

Description

technical field [0001] The invention relates to a wax transmission and printing structure of a three-dimensional printer, more specifically, the invention relates to a new three-dimensional waxing printer used in the technical field of mechanical engineering and its use method. Background technique [0002] Most of the current 3D waxing printers use air pressure deposition technology or fusion deposition technology, that is, the granular hot-melt material is heated and melted, and extruded through a nozzle with a fine nozzle. The spray head can move along the directions of X and Y axes, while the workbench can move up and down along the direction of Z axis. If the temperature of the hot melt material is always slightly higher than the solidification temperature and the temperature of the molded part is slightly lower than the solidification temperature, it can ensure that the hot melt material can be fused with the deposit of the previous layer immediately after it is extrud...

AI Technical Summary

Problems solved by technology

[0007] (2) In the fused deposition technology, the power of the heater for melting the raw material cannot be too high, so the filament used is generally a thermoplastic or wax with a low melting point, but the strength of the wax after being formed into a filament is very low, so it cannot Conveyed through the feed roller to the exit
