3D printing system

Abstract

The invention discloses a 3D printing system, which comprises a rack, a printing platform, at least a printing module, a feeding mechanism and a Z-axis movement mechanism used for driving the printing platform to move in the longitudinal direction. The printing platform, the printing module, the feeding mechanism and the Z-axis movement mechanism are arranged on the rack. The printing module contains at least a printer head, an X-axis movement mechanism used for driving the printer head to move in the transverse direction and a Y-axis movement mechanism used for driving the printer head to move in the longitudinal direction. The printer head is connected to a single-chip microcomputer control circuit board. There can be multiple printer heads on the printing system. According to the printing system, the number of the printing modules and the number of the printer heads on the printing modules can be increased at random so as to achieve the purposes of upgrading, upgrading of function and production capacity expansion for the printing system. Multiple printer heads can be adopted simultaneously to print one article. Thus, printing efficiency is effectively raised. Consumables in different colors can be used for color printing. The printer heads with different material consumables can be adopted for mix-material printing.

Description

technical field [0001] The invention relates to a 3D printing system. Background technique [0002] 3D printing does not need paper or ink, but is based on the computer's three-dimensional design model, through the software layered discrete and numerical control molding system, using laser beams, hot-melt nozzles, etc. to process metal powder, ceramic powder, Special materials such as plastics and cell tissues are stacked and bonded layer by layer, and finally superimposed to form a physical product. Its advantage is that it greatly saves the time for making industrial samples, and can "print" products with complex shapes. [0003] Existing 3D printing systems based on FDM (Fused Deposition Modeling) technology generally use a single print head or a fixed-pitch dual print head structure, and industrial 3D printers mostly use SLA forming technology. Fused deposition (FDM) is sometimes called fused filament deposition, which heats and melts filamentous hot-melt materials, an...

AI Technical Summary

Problems solved by technology

3D color printing is generally achieved by using a special print head with special consumables, and the equipment cost is relatively high

3D printing is mostly single-material printing. When an object has multiple requirements for materials, it is generally met by combining multiple objects of different materials. It is necessary to design the combined structure of each object, adding redundant structures and processes. Increased design difficulty and cost

[0005] Therefore, the existing 3D printers have the disadvantages of low work efficiency, the inability to realize the simultaneous use of multiple colors and materials, and the inability to perform functional upgrades and expand production capacity. The practicability needs to be strengthened.
