Problems solved by technology

[0004] Usually, in order to solve the above problems, before the empty path, the material of the extruder will be moved in the opposite direction for a certain distance, that is, the retraction action, to reduce the residual material in the nozzle and reduce the drawing, but because the material in the nozzle is already in a fluid state The state is not solid, so the retraction action cannot play a very good effect, and there will always be a part of the material in the nozzle to cause the drawing problem

Embodiment 1

[0028] In this embodiment, a method for eliminating printing stringing, when the printer nozzle moves from the contour path P A The end position A jumps to another contour path P B When the starting position B of , perform the following steps:

[0029] Step 1. The nozzle of the printer starts from point A and moves along a specific path with a minimum length of D, and performs an action of eliminating wire drawing; wherein, the specific path is the contour path P A The offset contour path E obtained after reducing the offset with parameter α A ,Such as figure 2 shown. The minimum length of the wire disappearing path is calculated as follows: D=L AB × R D , where L AB is the idling path length between the end position A and the start position B, R D is the disappearance coefficient.

[0030] Step 2. After performing the thread removal action, the printer nozzle jumps from the current position to the start position B to continue printing.

[0031] Before executing step...

Embodiment 2

[0036] In this embodiment, a method for eliminating printing stringing, when the printer nozzle moves from the contour path P A The end position A jumps to another contour path P B When the starting position B of , perform the following steps:

[0037] Step 1. Starting from point A, the printer nozzle moves a thread elimination path with a minimum length of D in a specific area, and performs an action of eliminating thread drawing; wherein, the specific area is the contour path P A The fill path F within A ,Such as image 3 shown. The minimum length of the wire disappearing path is calculated as follows: D=L AB × R D , where L AB is the idling path length between the end position A and the start position B, R D is the disappearance coefficient.

[0038] Step 2. After performing the thread removal action, the printer nozzle jumps from the current position to the start position B to continue printing.

[0039] Before executing step 1, it should be ensured that the origin...

Embodiment 3

[0044] Yet another embodiment of the present invention also provides an FDM printing device, which adopts the method for eliminating printing stringing as described in Embodiment 1 or Embodiment 2 during printing.

Abstract

The invention discloses a method for eliminating printing drawing filaments. When a printer nozzle skips from the end position A of an outline route PA to the starting position B of the other outlineroute PB, the following steps are executed: 1, the printer nozzle moves for the filament eliminating route with the minimum length D along a specific route or in a specific area from the A point, andan drawing filament eliminating action is conducted; and 2, after the drawing filament eliminating action is conducted, the printer nozzle skips from the current position to the starting position B tocontinue printing, wherein the specific route is a bias outline route EA obtained after reduction bias with a parameter alpha is conducted on the outline route PA, and the specific area is a fillingroute FA in the outline route PA. According to the method, the filament eliminating routes are set, when the nozzle moves on the filament eliminating routes, generated drawing filaments can adhere tothe routes, that is to say, the interior of a model is printed, and then the drawing filament phenomenon generated when the printer nozzle skips among different areas is eliminated.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for eliminating printing stringing, an FDM printing device, a storage medium and a processor. Background technique [0002] 3D printing technology is actually a general term for a series of rapid prototyping technologies. Its basic principle is stacked manufacturing. The rapid prototyping machine forms the cross-sectional shape of the workpiece through scanning in the X-Y plane, and the layer thickness is intermittently measured at the Z coordinate. displacement, and finally form a three-dimensional workpiece. FDM fused layer deposition modeling technology is a kind of 3D printing. It heats and melts filamentous hot-melt materials. At the same time, under the control of the computer, the three-dimensional nozzle selectively coats the material on the workbench according to the cross-sectional profile information. On, a layer of section is formed after rapid cooling. ...
