Description
Technical Field
[0001] This application relates to the field of 3D printing technology, specifically to a filament welding device. Background Technology
[0002] In the use of FDM printers, in order to reduce the waste of filament, it is necessary to splice two printing filaments. For example, the 3D printing consumable welding device disclosed in patent application number 2024201908272 uses Teflon tubing for heat conduction to weld the filament. The advantage is that the filament weld is smooth. The disadvantage is that it is necessary to hold the two filament joints and feed them into the Teflon tubing. When the operator's hand is free to press down the first cover, it is not easy for the two filament joints to maintain continuous contact. Therefore, after welding, there is a risk of insufficient welding, insufficient material at the welding point, or welding gaps. This results in the filament being weak after welding, and the filament is also prone to being pulled off during printing.
