Problems solved by technology
Existing 3D printers generally only have three degrees of freedom. When printing parts on inclined structures, it is often necessary to pre-print a large number of brackets as supports, resulting in waste of materials.

Embodiment Construction
[0025]In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not to limit the scope of the invention. Further, in the following description, a description of known structures and techniques is omitted to avoid unnecessary obscuring the concepts of the present invention.
[0026]A three-shot head five-degree-of-freedom 3D printer, such asfigure 1 As shown, the printing head mechanism 1 is mounted, the XYZ axis motion mechanism 2 of the printing head mechanism 1 is mounted, and the flip print platform 3 is disposed below the XYZ axis moving mechanism 2. Such asfigure 2 withimage 3 As shown, the XYZ axial motion mechanism 2 includes an outer frame 21, a cross shaft mechanism 22, a third screw mechanism 23, a Z-axis guide 2. The cross-axle mechanism 22 includes two sets ...

The invention discloses a three-printing head five-degree-of-freedom 3D printer, and belongs to the technical field of multi-degree-of-freedom 3D printing. The three-printing head five-degree-of-freedom 3D printer comprises a printing head mechanism, an XYZ-axis movement mechanism for mounting the printing head mechanism, and a turnover printing platform arranged below the XYZ-axis movement mechanism, wherein and the printing head mechanism switches three printing heads mounted on a spray head support through a first lead screw nut mechanism. According to the three-printing head five-degree-of-freedom 3D printer, the three printing heads can be freely switched, the printing efficiency is improved, the possibility that different printing materials are printed at the same time is increased, a printing platform can turn over around the X axis and the Y axis at a certain angle through a three-branch parallel mechanism, the degree of freedom of the printer is improved, the number of supporting brackets needing to be printed in advance when parts on an inclined structure are printed is reduced, and waste of materials is reduced.
Description
Technical field[0001]The present invention belongs to the field of multi-freedom 3D printing technology, and more particularly to a three-spray head five-degree-of freedom 3D printer.Background technique[0002]3D printing (3DP), one of the rapid molding technology, also known as the additive manufacturing, is a bonded material such as a digital model file, using a powder metal or plastic, and is constructed by layers. The technique of objects. Existing 3D printers typically have only three degrees of freedom, and often require a large number of brackets as support when printing inclined structures, causing waste of materials. At the same time, traditional printing equipment generally has only one nozzle, and complex parts sometimes require a variety of colors or materials to complete, and the printing efficiency can be improved by increasing the number of nozzles, or the diversity of printing can also be increased. By designing a printing system that combines multijets and multi-free...
