Problems solved by technology
[0015]
However, gaskets deteriorate rapidly, resulting in frequent gasket replacements requiring disassembly and reassembly of the head, which increases the time and cost of maintenance operations
[0016]
Also, known types of printheads do not allow the control and distribution of low flow rates, so the precision of molten metal deposition is limited

Abstract
The head (1) for the three-dimensional printing of molten metal comprises a 5 hollow body (2) comprising: a first chamber (3) adapted to contain a molten metal (4) in which a dispensing opening (5) isformed for the dispensing of the molten metal (4); a second chamber (9) adapted to contain an operating fluid (10) and connected to pressure variation means (11) adapted to define a pressure 10 difference between the first chamber (3) and the second chamber (9); and a dispensing assembly (12, 13) comprising a flexible laminar element (12) separating the first chamber (3) and the second chamber (9), the laminar element (12) being deformable by means of a pressure variation in the second chamber (9) and the deformation of the laminar element (12) determining the outflow of the molten metal (4)from the dispensing opening (5).
Description
technical field [0001] The invention relates to a printing head for three-dimensional printing of molten metal. Background technique [0002] It is known to use three-dimensional printing heads fitted on special printing devices. These printheads allow the creation of three-dimensional objects of various shapes without the use of molds. [0003] There are many materials for 3D printing, and even in most cases, 3D printers use polymeric materials that are in a molten state through a 3D digital model designed with a special print head that can make objects of interest. [0004] However, products require the use of materials other than polymers, such as metals, so 3D printing devices designed for use with metals have become more common in recent years. [0005] In particular, such devices are equipped with special printing heads that allow molten metal to be distributed on a support surface according to a pre-established digital model. [0006] An example of a printhead for ...
