A dot-matrix self-fusing 3D printing device

Abstract

The invention discloses a dot-matrix self-melting 3D printing device, which includes a light-emitting controller; a light-emitting device group, which is controlled by the light-emitting controller, and the light-emitting device group includes a plurality of light-emitting devices arranged in a dot matrix; a driver group, the driver group receives the signal command of the light emitter group, and moves and / or heats the printing consumables, the driver group includes several drivers; and, the forming tray; wherein, the driver is located under the light emitter, and the number of the driver is not less than the number of the light emitter. The invention is suitable for specific printing consumables, that is, a self-fusing FDM wire for 3D printing, without the need for a hot-melt nozzle, and the FDM wire itself can be heated and melted, and the state of the FDM wire at each coordinate point can be controlled through dot matrix settings In order to realize the removal of the moving device in the two directions of the X-axis and the Y-axis, the volume of the 3D printing equipment is reduced, and the entire layer of printing can be completed at one time, which improves the printing efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a lattice self-melting 3D printing device. Background technique [0002] 3D printing is a cumulative manufacturing technology, that is, rapid prototyping technology. It is based on a digital model file, using special wax, powdered metal or plastic and other bondable materials to print layers of bonding materials. Create three-dimensional objects. At present, the most widely used printing process in 3D printing technology is FDM, that is, fused deposition manufacturing process. The consumables are generally thermoplastic materials, such as wax, ABS, nylon, etc., and are supplied in the form of filaments or rods. 3D printing needs to be equipped with high-temperature nozzles , the material is heated and melted in the nozzle, and the nozzle moves along the section profile of the part and the filling track while extruding the molten material, and the material solidifies rapidly ...

AI Technical Summary

Problems solved by technology

The traditional FDM process requires an additional printing nozzle for heating, which is time-consuming and laborious. However, our company has developed a self-fusing 3D printing FDM wire, which does not require a hot-melt nozzle. The FDM wire itself can be heated and melted, and there is no matching one on the market 3D printing equipment, in view of the above problems, it is necessary to propose further solutions
