Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a size-adjustable 3D printing wire winding disc. Background Art

[0002] The method of packaging 3D printing filaments is to wind the filaments on a reel. When transporting and selling 3D printing filaments, the reel on which they are wound is often transported and sold simultaneously. Since the reel is mostly made of plastic, metal and other materials, it is heavy and increases the transportation cost. At the same time, the manufacturing cost of the reel is high and accounts for about 10% of the total cost of the transported filaments and the reel.

[0003] Using a reel for packaging and transportation not only increases the transportation cost of the filament, but the reel is often difficult to reuse after use, which will cause economic losses and waste of resources. To solve this problem, some suppliers of consumables have adopted a packaging method without a reel. However, the sizes of reel-reels that can be used by various suppliers have not yet reached a unified standard, resulting in a reel that can only correspond to one specification of printing consumables and can only be provided exclusively by one supplier. This brings a lot of inconvenience and more investment to consumers. Therefore, it is necessary to improve the existing reel to suit printing consumables of different specifications. Therefore, we propose a new size-adjustable 3D printing filament reel. Utility Model Content
