Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, and in particular to a 3D printer tray support base. Background Technology

[0002] In the 3D printing process, stable support of the filament tray is one of the key factors in ensuring print quality. However, traditional 3D printer tray support bases have the following shortcomings: First, the support structure lacks stability, and the tray is prone to shaking when feeding filament, resulting in uneven filament feeding and affecting printing accuracy; second, the filament lacks effective guidance when exiting the tray, resulting in high feeding resistance and easily causing filament stretching, wear, or even breakage; third, the tray installation and disassembly process is cumbersome, making it difficult to quickly change trays of different sizes, reducing print preparation efficiency; fourth, the support base lacks moisture protection, while 3D printing filament easily absorbs moisture from the air, which can lead to defects such as bubbles and delamination during printing, seriously affecting print quality.
