Multi-material 3D printer

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...

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 facing the problem of rapid material conversion. The actual various parts or products are rarely composed of a single material, which requires 3D printing equipment to meet the requirements of multi-material printing. Still focus on single-material workpieces. In the case of multi-material printing, multiple print heads must be assembled together. The motor attached to each print head leads to the overall size of the print head being too large, which affects the effective molding size.
