Description

Technical Field

[0001] This application relates to the field of 3D printing technology, and more specifically to a filament drying and storage assembly for a 3D printer and a 3D printer using the assembly. Background Technology

[0002] Currently, in fused deposition modeling (FDM) 3D printing technology, directly using undried plastic raw materials for printing will result in air bubbles, affecting the printing effect. Therefore, to keep the printing filament dry, several filament drying boxes are available on the market. For example, the first type of drying box integrates the heating device and the box body, with one tray position, which can heat, dry, and store a single tray and a single roll of printing filament at a time. The second type of drying box expands the volume of the single box body to two tray positions, which can dry and store two rolls of printing filament at a time. The third type of drying box expands the volume of the single box body to four tray positions, which can dry and store four rolls of printing filament at a time.

[0003] However, these drying ovens face many shortcomings when used for multi-color printing. For example, if a printing factory has two four-color 3D printers and needs to dry eight rolls of printing filament simultaneously, the first type of drying oven would require eight sets of heating units and eight power supplies, which is inconvenient and costly. The second type would require four sets of heating units and four power supplies, again inconvenient and costly. The third type would only require two heating units and two power supplies, which is cheaper, but the weight when full of filament would make it difficult to move. Furthermore, because the rate of filament consumption varies during multi-color printing, the dryness of newly added or slowly consumed filament is inconsistent, making it impossible to selectively dry newly added filament. This wastes energy, occupies limited drying space, and wastes equipment resources.

[0004] Therefore, there is a need for a combined device for convenient drying and storage of printing filaments and a 3D printer that uses this combined device. Utility Model Content

In particular, the movable cover plate 212 is made of magnetic metal material.

[0084] Figure 10 This is a schematic diagram of the drying chamber of the filament drying and storage assembly for a 3D printer, as described in an embodiment of this application. Figure 4 As shown in the figure, the figure is a schematic diagram of the box 201 with a mesh cover 216 installed inside; the mesh cover 216 is set at the bottom of the box 201; the mesh cover 216 is used to cover the ventilation window 211 and the desiccant tank 214, mainly to prevent the volume of the desiccant 215 from exceeding the limit and obstructing the rotation of the material tray.

[0085] Figure 11 This is Embodiment 2 of the filament drying and storage assembly for a 3D printer according to the present application. As shown in the figure, the filament storage assembly 100 of the present application includes a hot air base box 1, a first drying chamber 21, a second drying chamber 22, an operation panel 3, and four sets of auxiliary filament feeders 4; the operation panel 3 is connected to the hot air base box 201;

[0086] Four sets of auxiliary wire feeders 4 can be detachably connected to the first drying box 21 and the second drying box 22. This is because the user can install the auxiliary wire feeders 4 on the first drying box 21 and the second drying box 22 at the same time; or install and use the auxiliary wire feeders 4 on either the first drying box 21 or the second drying box 22.

[0087] In this embodiment, since an auxiliary wire feeder 4 is used for auxiliary wire feeding, a power module 15, a control module 16, and an auxiliary wire feeding control module 19 also need to be configured accordingly (see...). Figure 4The auxiliary wire feeding control module 19 is electrically connected to the power supply module 15 and the control module 16. The auxiliary wire feeding control module 19 is also electrically connected to the auxiliary wire feeder 4 or an external 3D printer through the interface module 191. The auxiliary wire feeder 4 is used to electrically assist in feeding the printing filament. The auxiliary wire feeding control module 19 is used to control the operation of the auxiliary wire feeder 4.

[0088] Since a control module 16 is configured accordingly in this embodiment, the operation panel 3 can be electrically connected to the control module 16; the operation panel 3 is used to provide a display and interactive operation interface for the user, thereby setting control parameters for the control module 16.

[0089] In this embodiment, the control module 16 can be used to automatically control the first hot air duct module 13 and the second hot air duct module 14 in a program-controlled manner to achieve the automatic temperature-controlled drying function of the printing filament.

[0090] Figure 12 This is Embodiment 3 of the filament drying and storage assembly for a 3D printer according to the present application. As shown in the figure, the filament storage assembly 100 of the present application includes a hot air base box 1, a first drying chamber 21, a second drying chamber 22, an operation panel 3, and two sets of auxiliary filament feeders 4; the operation panel 3 is connected to the hot air base box 201; and a dovetail-groove type quick-release mounting slot 41 is provided on the upper part of the first drying chamber 21 and the second drying chamber 22 for installing the auxiliary filament feeders 4; in this figure, since the auxiliary filament feeders 4 are not installed on the first drying chamber 21, the mounting slot 41 is exposed; the second drying chamber 22 is also provided with a dovetail-groove type quick-release mounting slot 41, but due to the view obstruction, the mounting slot 41 is not exposed;

[0091] Two sets of auxiliary wire feeders 4 are detachably connected to the second drying box 22, because the user can install and use the auxiliary wire feeders 4 only on the second drying box 22; while the first drying box 21 is used as a general drying and storage box.

[0092] Specifically, four sets of cable outlet holes 219 are provided at the front and rear positions of the upper part of the first drying chamber 21 and the second drying chamber 22 for cable outlet. The purpose of providing four sets of cable outlet holes 219 is to allow users to select to lead out the cable forward or backward. At the same time, a plug 220 is provided for the front cable outlet hole 219, which is not frequently used under normal circumstances, to seal the air holes of the cable outlet hole 219, so as to facilitate long-term dry storage of the printing cable.

[0093] Figure 13This is a schematic diagram of the printing use of the filament drying and storage assembly for a 3D printer according to an embodiment of this application. As shown in the figure, the filament storage assembly 100 of this application, after being equipped with an auxiliary filament feeder 4, is used in conjunction with a 3D printer 300. The auxiliary filament feeder 4 is connected to the printer extrusion nozzle 302 via a flexible conduit 301. The auxiliary filament feeder 4 can deliver the filament through the flexible conduit 301 to the printer extrusion nozzle 302 for printing. The flexible conduit 201 can reduce the resistance of filament delivery.

[0094] As shown in the diagram, users can dry four rolls of printing filament simultaneously and choose any one roll to connect to the 3D printer 300 for printing. Furthermore, the positions of the two drying chambers can be interchanged, allowing the filament and drying chamber in use to be closer to the 3D printer 300; or replacing a drying chamber that has already been heated and dried.
