Abstract
Various embodiments provide a filament replacement mechanism for a 3D printer and a 3D printing system. In those embodiments, the filament replacement mechanism includes: a support; a filament guide unit disposed on the support and including a plurality of secondary filament guide tubes and a filament guide opening connecting with the plurality of secondary filament guide tubes, where the filament guide opening is configured to be jointed with a main filament guide tube of the 3D printer; and a plurality of filament replacement units disposed on the support.
Claims20
A 3D printing system, comprising:
- a 3D printer;
- a multi-channel member, the multi-channel member has an outlet and a plurality of inlets connecting with the outlet, and the outlet is connected to the 3D printer;
- and
- a plurality of filament replacement units, each of the plurality of filament replacement units comprises:
- a supporting shaft assembly, which is in contact with a rim of a corresponding filament spool so as to support the corresponding filament spool;
- and
- a loading and unloading mechanism, which is provided with a channel for the filament to penetrate through;
- wherein the 3D printing system further comprises a plurality of secondary filament guide tubes, one secondary filament guide tube connects to one inlet of the multi-channel member, and the channel of the loading and unloading mechanism is connected to the inlet of the multi-channel member through a corresponding secondary filament guide tube;
- wherein the loading and unloading mechanism is configured to drive a filament wound around the corresponding filament spool to enable the filament to be guided into the multi-channel member via one corresponding secondary filament guide tube of the plurality of secondary filament guide tubes so as to perform a loading operation, and configured to drive the corresponding filament spool to rotate such that the filament withdrawn from the 3D printer is rewound around the corresponding filament spool so as to perform an unloading operation.
