Automatic silk changing 3D printer

Abstract

The invention relates to an automatic silk changing 3D printer. The automatic silk changing 3D printer comprises a printer frame, extruders, a six-in-one automatic wire cutting and printing head, a printing head driving system, a control module and a power supply module, wherein the extruders are arranged on the top of the printer frame, the six-in-one automatic wire cutting and printing head is arranged on a printer effector, the printer effector can be installed on the printer frame in an up-and-down sliding mode, a hot bed which is used for putting a to-be-printed product is arranged belowthe six-in-one automatic wire cutting and printing head, respective printing silks of the six extruders are respectively sent to the corresponding position of the six-in-one automatic wire cutting andprinting head, when the silks need to be changed, the six-in-one automatic wire cutting and printing head moves upwards, and a shearing shaft is driven to cut the previous printing silk by a miniature direct-current speed reducing motor. According to the automatic silk changing 3D printer provided by the invention, the printing silks can be quickly changed with high efficiency and without residue, single-head multi-color multi-material printing can be realized, and the automatic silk changing efficiency and adaptability are greatly increased.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer with automatic filament change. Background technique [0002] 3D printing, also known as additive manufacturing technology, is a rapid prototyping technology that uses digital modeling software to build up raw materials layer by layer through printing nozzles, thereby realizing the transformation from three-dimensional blueprint files to physical objects. Similar to the original 2D printing technology, only the printing materials are different. Ordinary printers use ink and paper, while 3D printers use powdered adhesive materials such as plastics, metals, ceramics, wood chips, and gravel. 3D printing has considerable imagination and can be applied in a wide range of fields, such as traditional manufacturing, as well as automobiles, consumer electronics, medical equipment, and construction engineering. These fields can be combined with 3D printing to achieve bett...
