Embodiment Construction

[0036] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as Figure 1 to Figure 3 As shown, a 3D printer extrusion system capable of automatically switching print heads includes a fixed print head assembly 1 , a fixed base 2 , a switching assembly, a movable base 6 and a movable print head assembly 7 . The fixed print head assembly 1 is fixedly installed on the fixed base 2, and its position remains unchanged. The movable print head assembly 7 is fixedly installed on the movable base 6, arranged in parallel with the fixed print head assembly 1, and the switching assembly is used to drive the movable base. The seat 6 slides vertically up and down parallel to the fixed base 1 and is positioned at the set position, thereby driving the entire movable print head assembly 7 to sli...

Abstract

The invention discloses a three-dimensional printer extrusion system capable of automatically switching a printing head. The three-dimensional printer extrusion system capable of automatically switching the printing head comprises a fixed base, a fixed printing head assembly arranged on the fixed base, a movable base arranged on the fixed base in a lifting and displacement way, a movable printinghead assembly arranged on the movable base, and a switching assembly for moving and positioning the movable base. The switching assembly comprises a micro guide rail assembly for guiding the movable base, a switching motor for driving the movable base, and a sensor for positioning the movable base. According to the three-dimensional printer extrusion system capable of automatically switching the printing head provided by the invention, through designing the movable printing head assembly and the fixed printing head assembly, the switching of the height difference between the two printing headassemblies can be realized through switching the height of the movable printing head assembly, and the movable printing head assembly and the fixed printing head assembly are independent so as to be free of being interacted in any case during printing, so that the printing accuracy is ensured.

Description

technical field [0001] The invention relates to a three-dimensional printer based on a fusion deposition rapid prototyping process, in particular to a three-dimensional printer extrusion system capable of automatically switching print heads. Background technique [0002] The 3D printer based on the fusion deposition rapid prototyping process uses plastic filaments with a diameter of about 1-2 mm, and melts and extrudes the plastic filaments into filaments of about 0.2-0.4 mm through a computer-controlled printing extrusion head and prints them layer by layer. stacked into three-dimensional objects. Usually, the fused deposition rapid prototyping process needs to add supports when manufacturing objects with cantilever structures. If the extrusion head of the 3D printer only has a single melt channel design structure, the printed object and support can only be constructed with the same material. Although during the printing process, the support part can be loosened by contro...
