Problems solved by technology

[0004] Since many products have more than two different colors or are composed of more than two materials of different materials, the existing 3D printers need to frequently replace raw materials when printing three-dimensional products composed of multiple colors or materials. The operation is troublesome, and the printing quality of the product will be affected due to the existence of residual material in the nozzle
At the same time, various rapid prototyping technologies are faci

Embodiment 1

[0027] A multi-material 3D printer, the 3D printer includes a shell, the shell includes a front door 1, a rear wall 2 and two side walls, a base 3, a workbench 4, a nozzle 5, and a three-dimensional motion mechanism are arranged in the shell , a feeding unit and a storage unit, the 3D printer is connected to the controller 6, the controller 6 adopts a single-chip microcomputer, the base 3 is provided with a power supply, the controller 6 is connected to the power supply, and the three-dimensional movement The mechanism is driven by a servo motor 7, and the servo motor 7 is electrically connected to the controller 6. The three-dimensional motion mechanism includes an X-axis motion mechanism, a Y-axis motion mechanism and a Z-axis motion mechanism, and the X-axis motion mechanism is an X-axis sliding mechanism. Guide rail 8, the nozzle 5 can slide left and right on the X-axis sliding guide rail 8, the Y-axis motion mechanism includes two Y-axis sliding guide rails 9 symmetrically...

Embodiment 2

[0031] When using the present invention to 3D print circuit boards, the required materials (such as conductive ink, etc.) are placed in the storage tank, and the graphics and material data of the printed circuit boards are first processed by computer software to design a three-dimensional print that needs to be printed. The three-dimensional model of the solid object is sliced ​​and layered along the computer internal direction corresponding to the actual vertical direction to obtain the forming data of each layer. Afterwards, the graphic information data corresponding to the material is sent to the valve controller corresponding to the material, and the nozzle is driven by the three-dimensional motion mechanism and under the action of the feeding drive device, and the required circuit is printed layer by layer on the workbench plate.

Abstract

The invention discloses a multi-material 3D printer. The multi-material 3D printer comprises a housing. A base, a worktable, spray nozzles, a three-dimensional movement mechanism, a feeding unit and a storing unit. The multi-material 3D printer is connected with a controller. A power supply is arranged below the base, and is connected with the controller. The three-dimensional movement mechanism is driven by a servo motor. The servo motor is electrically connected with the controller. The three-dimensional movement mechanism comprises an X-axis movement mechanism, a Y-axis movement mechanism and a Z-axis movement mechanism. Feeding driving devices are arranged on the spray nozzles, and are electrically connected with the controller. The feeding unit comprises a plurality of guiding pipes. One end of each guiding pipe is connected with the corresponding spray nozzle, and the other end of each guiding pipe is connected with the feeding unit. Valve controllers are arranged on the guiding pipes, and are electrically connected with the controller. The worktable is positioned on the base.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, in particular to a multi-material 3D printer. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a cumulative manufacturing technology, that is, a machine of rapid prototyping technology. It is based on a digital model file and uses special wax, powdered metal or plastic to bond materials, which create three-dimensional objects by printing layers of adhesive materials. At this stage 3D printers are used to manufacture products. The technology of constructing objects by printing layer by layer. The principle of a 3D printer is to put data and raw materials into the 3D printer, and the machine will build the product layer by layer according to the program. There are various forms of stacking thin layers by 3D printers. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are var...
