Benefits of technology

This patent describes a new type of three-dimensional printer that can quickly create three-dimensional objects made of metal. The printer has a method for printing these objects using a special material that is specifically designed for metal printing. The goal of this patent is to offer a faster and more efficient way to create metal three-dimensional objects.

Problems solved by technology

The 3D printer uses a method in which the wire material is melted and accumulated layer by layer, resulting in a relatively long print shaping time.
In addition, because the layers of the shaping material are cooled and connected after being bonded by only the molten material, when material temperatures of the layers are different, the adhesion relationship between the layers is unstable, resulting in unstable structural strength of the shaped object.
However, the laser sintering method needs to consume a large amount of energy to make the powder shaped after being melted at a high temperature, and this type of 3D printing device needs professional maintenance and consumes extremely high costs.
This printer is not only inefficient in powder laying, but also needs to consume a large amount of energy in the laser sintering process, and this also reduces the working efficiency.

first embodiment

[0060]Preferably, the printing material is formed by uniformly mixing the metal powder with the binder, or the printing material forms a strip-shaped printing material by mixing the metal powder with the binder. Specifically, the table of FIG. 2 provides five different compounding ratios of the printing material in this embodiment. Compared with the foregoing first embodiment, the metal powder in this embodiment has a relatively large specific gravity, the metal powder has a specific gravity of more than 70%, and the shaped three-dimensional object has a relatively large density, and the hardness and strength of the sintered and shaped three-dimensional object are also accordingly improved.

[0061]In other groups of embodiments, the types that are of the metal powder and the binder and that are specifically selected in the first embodiment and the second embodiment can be used in overlapping and paired manners. Other additional components, such as pigments and magnetic materials can a...

second embodiment

[0073 of a Metal Three-Dimensional Printer:

[0074]As shown in FIG. 6, the metal three-dimensional printer of this embodiment is an FDM three-dimensional printer, including a printing head 110, a heating apparatus 120, a printing platform 130, a water tank 140, an airtight chamber 150, and a sintering shaping chamber 160. The printing head 110, the heating apparatus 120, the printing platform 130, and the water tank 140 are disposed in the airtight chamber 150. The interiors of the airtight chamber 150 and the sintering shaping chamber 160 have vacuum environments or inert gas environments. Certainly, the sintering shaping chamber 160 may also be disposed outside a body of the three-dimensional printer. That is, the sintering shaping chamber 160 may be disposed outside the airtight chamber 150.

[0075]The binder of this embodiment is a water soluble binder. The printing material is processed into a strip-shaped printing material by the metal powder with the water soluble binder. The man...

Abstract

A metal three-dimensional printer, a printing method, and a three-dimensional printing material. The three-dimensional printer includes a printing head, a heating apparatus, a printing platform, and a sintering shaping chamber. The printing method includes a preliminary shaping step and a sintering step. The heating apparatus heats the three-dimensional printing material. A heating temperature of the heating apparatus is 50° C. to 300° C., and a binder bonds metal powder at 50° C. to 300° C., and the three-dimensional printing material is extruded onto the printing platform to form a preliminary cured object. In the sintering step, the preliminary cured object is sintered and cured into a shaped object.
