Abstract

An embodiment of the invention discloses a 3D printing file generation method and device, computer equipment and a storage medium. The method comprises the steps of carrying out layered slicing on a to-be-printed three-dimensional model, and acquiring a printing path and an idling path in each layer of slice; determining the size of consumable materials capable of being left at the tip of a nozzle according to the nozzle hole diameter of a printer; determining a tail end sliding path in a previous printing path of the idling path according to the size of the consumable materials, and setting the extrusion flow in the tail end sliding path to be zero; and generating a 3D printing file according to the printing path with the extrusion flow and the idling path. The last section of the previous printing path of the idling path is changed into the idling tail end sliding path, so that discharging is just not continued after printing of the previous printing path is completed, on the basis that the integrity of the printed three-dimensional model is guaranteed, the wire drawing problem existing in the 3D printing process by applying the FDM process is solved, and the printing effect of the appearance of the three-dimensional model is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of 3D printing file generation, and in particular, to a method, device, computer equipment, and storage medium for generating a 3D printing file. Background technique [0002] For the existing Fused Deposition Modeling (FDM) printing method, when the printer completes the current printing path and moves to the next printing path, the consumables in the nozzles in the empty path will overflow due to the effect of gravity and cause stringing. [0003] The current FDM slicing software algorithm mainly relies on the retraction function, that is, the consumables are withdrawn immediately after the current printing path is completed, and the previously retracted length is re-extruded after the empty run is completed and before moving to the next printing path. However, because the consumables in the nozzle are in a molten state, it usually causes incomplete retraction, especially for the ...
