Abstract

The invention discloses a blender of a melt extrusion type color 3D (three-dimensional) printing head. The blender comprises a blending support, a heating block arranged in the blending support, heating rods inserted into the heating block, a primary blending chamber fixed to the bottom of the heating block, a secondary blending chamber disposed at the bottom of the primary blending chamber and heat insulation rods inserted into the secondary blending chamber, symmetrical inclined planes are arranged on the blending support, and piezoelectric bimorphs are fixed to the symmetrical inclined planes. The secondary blending chamber comprises two vibration reduction feed pipes, an array blending ring and a discharge opening, the upper ends of the vibration reduction feed pipes are communicated with the bottom of the primary blending chamber, the lower ends of the same are connected with the upper portion of the array blending ring, and the bottom of the array blending ring is connected with the discharge opening. Molten materials of three primary colors can be blended fully so as to blend pure material colors, and printing resolution is unaffected in the blending process.

Description

【Technical field】 [0001] The invention relates to the technical field of three-dimensional molding, in particular to a mixing driving mechanism of a melt extrusion color 3D printing head. 【Background technique】 [0002] Fusion Extrusion Molding (FDM) is a widely used three-dimensional molding technology. Its working principle is to heat and melt the material, extrude it from the print head through the extrusion mechanism, and rapidly cool and solidify it. This technology was only used in the early stage of application. Limited to single-color material molding, so the color types of printed objects are monotonous, and the color selection is limited by the color of the material. With the continuous development of technology, people later developed a melt extrusion color 3D printing head that works on the principle of mixing three primary colors. Out of shape. [0003] In the current searchable patents or literature, there are many descriptions of the principle or structure o...
