[0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis and uses powdered metal or plastic and other adhesive materials to construct objects by printing layer by layer. 3D printing is usually achieved using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology.

[0003] In the prior art, there is a hybrid color 3D printer with patent announcement number CN219856001U. The above patent replaces the thermoplastic material with a liquid raw material to ensure the uniform mixing of the three primary color raw materials, so that the subsequent printing has uniform color and good printing effect. However, there are still the following deficiencies in actual use: from a practical point of view, when the printer stirs and mixes the liquid raw material, the liquid raw material is easy to adhere to the inner wall of the mixing box, causing waste of raw materials and affecting the mixing effect, thereby resulting in unsatisfactory printing effect. Moreover, the printer cannot disassemble the mixing box, and cannot clean, repair or replace the internal stirring shaft and stirring rod, affecting the use of the printer.

[0004] Therefore, a hybrid multi-material 3D printer is needed to solve the problems in the prior art that the liquid raw materials are easily adhered to the inner wall of the mixing box and the internal stirring shaft and stirring rod cannot be cleaned, repaired or replaced. Utility Model Content

[0026] The movable mechanism 5 can be used to drive the print head 7 to move to various positions to meet different printing requirements.

[0027] Further Figure 1 , Figure 3 and Figure 4 As shown, it is worth specifically explaining that the stirring mechanism 6 is composed of a fixed plate 601, a first flange 602, bolts 603, a motor 604, a connecting shaft 605, a second flange 606, a stirring shaft 607, a connecting plate 608, a scraper 609 and a stirring drum 611.
