MULTI-FUNCTION AND MULTIFUNCTIONAL 3D PRINTER AND ITS PRINT HEAD

摘要

The invention relates to 3D printing using FDM technology, in particular to the creation of a multi-nozzle and multifunctional printer and its print head. The objective of the invention is to create a 3D printer for the manufacture of three-dimensional forms, having a multi-nozzle and multifunctional print head. The technical result is expressed in increasing the functionality of the print head, which can use various types of printing material, different diameters and different colors, without stopping the process of printing three-dimensional forms, which allows you to get products with better qualities and properties and increase productivity. The technical result is achieved by the fact that the declared 3D printer includes a multi-nozzle print head, on which the assembled extruders are fixed along the radius, having a heating element and a nozzle, pressure mechanisms and fittings for supplying plastic, the print head has the ability to rotate on support bushings, on shaft for changing nozzles during printing, with different material properties, depending on the program of layer-by-layer creation of the product. A gear wheel for plastic extrusion, which is common for all extruders, is also used, which has the shape of a cylinder and is tapered on both sides, and the gear wheel is made with the ability to move freely in a longitudinal groove on the side of the print head housing.
