Problems solved by technology

This feeding method will also cause the remaining material in the material tube to be discarded directly because the corresponding amount of material cannot be estimated. As far as chocolate is concerned, the remaining material in the material tube cannot be melted and reused, because this will increase the impurities in the raw material leading to clogging
[0005] Existing barrel extrusion type 3D printers have a certain capacity limitation, and underestimation of the amount of material in the barrel will cause semi-finished products to be printed during the printing process.

Abstract

The invention relates to the technical field of 3D printers, in particular to a material tube material weight calculating method of a material tube piston extrusion type 3D printer. An upper limit sensor is arranged at the upper end of the moving Z-axis direction of a material rod fixing device, and a material rod limiting sensor is arranged on the material rod fixing device; the material weight in a material tube can be accurately calculated based on the printing manner of the piston extrusion type 3D printer, semi-automatic material return can be achieved, the situation that the material rod fixing device is located at a zero position is guaranteed, and the material weight in the material tube can be continuously calculated; and semi-automatic feeding can be achieved, the situation that the material rod fixing device is located at the zero position is guaranteed, the material weight in the material tube can be continuously calculated, and a model file can be split and printed according to the material weight needed for printing the model file and the material weight of the material tube.

Description

Technical field [0001] The present invention relates to the technical field of 3D printers, and more specifically to a method for calculating the amount of material of a barrel of a barrel piston extrusion type 3D printer. Background technique [0002] Fused deposition rapid prototyping (FDM) is one of the main 3D printing technologies. FDM technology, also known as hot-melt stacking technology, is to extrude hot-melt filaments from the nozzle after heating and melting, and deposit them on the printing work platform or the solidified material of the previous layer. When the temperature is lower than the curing temperature of the filaments Then it begins to solidify and form, and finally prints into a solid. Due to the need for corresponding insulation facilities for chocolate, the general continuous tube feeding method is not suitable. [0003] The existing screw extrusion type continuous feeding method can solve the problem of continuous feeding to a certain extent. This printer...
