In recent years, 3D printing technology has been increasingly popularized in fields such as design, manufacturing, scientific research and education.

[0003] 3D printing filament is one of the commonly used consumables for 3D printing equipment. It is usually stored in a filament reel (also known as a "filament spool").

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This embodiment provides a filament storage wheel for 3D printing, which can be applied in 3D printing equipment to store 3D printing filament and guide its direction.

[0026] Please see Figures 1-4 The 3D printing filament storage wheel of this embodiment includes a filament storage wheel body part 1 formed by injection molding, which is generally disc-shaped or wheel-shaped.

[0027] The center of the wire storage wheel body part 1 is configured as the shaft mating part 3, and the outer periphery of the wire storage wheel body part 1 is configured as the wire storage function part 2. In fact, the shaft mating part 3 and the wire storage function part 2 are both integrally injection molded with the wire storage wheel body part 1.

[0028] Any 3D printing filament storage wheel can be stacked and fitted with another 3D printing filament storage wheel in the axial direction, so that the filament storage function part 2 is extended in the axial direction.

[0029] Specifically, baffles 21 are respectively arranged on both sides of the wire storage functional section 2. The baffles 21 are wall-like structures inclined to the wire storage reel body section 1, so that the baffles 21 and the wire storage reel body section 1 form a "Y"-shaped structure; and in the wire storage functional section 2, the top of one baffle 21 is configured as a snap-fit ​​part 22, and the top of the other baffle 21 is folded in the axial direction to form an assembly edge 23; as Figure 3 and Figure 4 As shown, when the 3D printing filament storage wheels are stacked and fitted together, the snap-fit ​​part 22 of one 3D printing filament storage wheel is connected to the assembly edge 23 of the other 3D printing filament storage wheel.

[0030] Specifically, the shaft mating part 3 has a shaft hole 31 at its center. In fact, the shaft hole 31 is a hole-like structure feature integrally injection molded with the wire storage wheel body part 1.

[0031] More specifically, the outer edges of the shaft hole 31 of the shaft mating part 3 extend along the axial direction of the wire storage wheel body part 1 at both ends to form axial mating ribs 32. In fact, the axial mating ribs 32 are cylindrical structural features integrally injection molded with the wire storage wheel body part 1. The axial mating ribs 32 are configured to increase the contact area between the shaft mating part 3 and external components.

[0032] Furthermore, the axial fitting rib 32 of the shaft fitting part 3 has a radial stop rib 33 formed at at least one end. In fact, the radial stop rib 33 is an annular rib structure feature integrally injection molded with the axial fitting rib 32; the radial stop rib 33 is configured to axially limit the external parts.

[0033] Furthermore, the main body 1 of the filament storage wheel has several weight-reducing holes 11 with the shaft mating part 3 as the center of symmetry, so as to save plastic material and reduce the weight of the filament storage wheel for 3D printing.

[0034] Furthermore, the filament storage wheel body 1 is provided with several reinforcing ribs 12 with the shaft mating part 3 as the center of symmetry, so as to improve the mechanical strength of the filament storage wheel for 3D printing.

[0035] In this embodiment, the shaft fitting portion 3 of the 3D printing filament storage wheel can be configured with a bearing or a metal ring. That is, the bearing or metal ring is embedded in the shaft hole 31, and the bearing or metal ring is axially limited by the radial stop rib 33. Alternatively, the shaft fitting portion 3 of the 3D printing filament storage wheel in this embodiment can be directly used in conjunction with the rotating shaft of the 3D printing equipment. That is, the shaft fitting portion 3 of the 3D printing filament storage wheel is directly sleeved on the rotating shaft of the 3D printing equipment.

[0036] The 3D printing filament storage reel of this embodiment can be used independently in 3D printing equipment; furthermore, as Figure 3 and Figure 4 As shown, several 3D printing filament storage wheels of this embodiment can also be configured and stacked together in the axial direction (in this case, the snap-fit ​​part 22 of the previous 3D printing filament storage wheel is connected to the assembly edge 23 of the next 3D printing filament storage wheel), so that the filament storage function part 2 is extended in the axial direction; in this way, the specifications of the 3D printing filament storage wheels of this embodiment can be easily adjusted to meet the usage requirements of 3D printing equipment of different models, specifications and usage scenarios, and have the excellent characteristics of flexibility, quick specification adjustment and recyclability.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
