Abstract
Description
Technical Field
[0001] This application relates to the field of 3D printing technology, and more specifically to a filament storage box for a 3D printer. Background Technology
[0002] In fused deposition modeling (FDM) 3D printing, using undried plastic raw materials directly for printing can result in air bubbles, affecting print quality. Therefore, the filament used for printing must be kept dry to ensure print quality. In addition, with current standard thickness spools and filaments, the filament supply is limited, leading to insufficient filament and the need to wait for refills when printing very large parts. Using spools and filaments that are half or more than half full is quite wasteful. Therefore, there is a demand for longer filaments and thicker spools.
[0003] Currently, single-box wire storage boxes are commonly used, which can only store one roll of standard thickness wire material at a time. However, standard thickness wire storage boxes do not take into account the applicability of longer wires and thicker rolls, and cannot keep more wires dry and stored. Therefore, the utilization rate of wire storage boxes is not high.
[0004] Meanwhile, current single-box wire storage boxes are generally designed with only one set of two rollers to support the trolley. Even if the single-box wire storage box is thickened and the rollers are lengthened so that it can hold two rolls of standard thickness wire at the same time, the wire consumption rate is not consistent when using the same roller. Therefore, this solution cannot supply wire to two printers at the same time.
[0005] Therefore, there is a need to propose a wire storage box that can improve the drying and storage utilization of wires without affecting the simultaneous supply of wires to two printers. Utility Model Content
