Multi-color 3D printing method, printer, printing device and computer storage medium

Abstract

The invention relates to a multicolor 3D printing method, a printer, a printing device and a computer storage medium. The method includes: printing the ith color consumable in the ith area of ​​the outer wall part of the current layer of the model body; inputting the (i+1)th color consumable into the printing nozzle; calculating the remaining capacity Q of the washing material area of ​​the current layer of the model body The size of the cleaning capacity Q1 of the cleaning area of ​​the print head; if the Q of the current layer of the model body is smaller than the Q1 of the cleaning area, the consumables in the cleaning area will be extruded to the storage box by the first extrusion amount (Q1‑Q); The (i+1)th area of ​​the outer wall portion of the current layer prints the (i+1)th color consumable. When changing colors in this application, it is obtained through calculation that the Q of the current layer of the model body is less than Q1, and then the color mixing consumables (Q1-Q) are extruded into the storage box, so that the color mixing consumables can be completely consumed, so as to ensure the color of the surface of the model body, and at the same time Save time and consumables consumption, improve printing efficiency and reduce printing costs.

Description

technical field [0001] The invention relates to the technical field of software processing, in particular to a multi-color 3D printing method, a printer, a printing device and a computer storage medium. Background technique [0002] The 3D printing technology based on FDM (Fused Deposition Modeling, Fused Deposition Manufacturing) is to heat and melt solid plastic filaments into liquid consumables, extrude them through nozzles, print them layer by layer on the workbench, and stack them to form a certain shape. shape, the stacked liquid consumables are solidified and formed after heat dissipation. At present, most of the multi-color 3D printing on the market adopts the method of multiple input and one output to print color 3D models. The refueling method is to return the consumable of the previous color, and then switch the consumable supply of another color. Due to the residual amount of the consumables of the previous color in the nozzle cavity, the printing color of the c...
