3D printer with excellent heat dissipation effect

Abstract

The invention discloses a 3D printer with an excellent heat dissipation effect. The 3D printer with the excellent heat dissipation effect comprises a housing, an internal framework, a printing platform (11) and a near end wire feeder, wherein the internal framework is mounted inside the housing, the internal framework comprises two vertical smooth guiding rods, the tops of the vertical smooth guiding rods are fixedly connected through a transverse smooth guiding rod, the near end wire feeder is fixedly connected onto the transverse smooth guiding rod, a heating component is arranged inside the near end wire feeder, a wire material guiding device is arranged in the middle of the heating component, the printing platform is fixed at the bottom of the internal framework, the housing adopts a shutter structure, so that heat produced during the running of equipment such as a stepping motor inside the 3D printer is enabled to be exchanged with the outside, the heat dissipation performance is improved, the working performance of the 3D printer is improved, the structure is simple, and the excellent heat dissipation effect can be achieved without the need of adding a new cooling device.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and in particular relates to a 3D printer with good heat dissipation effect. Background technique [0002] 3D printer is a digital model file-based technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In the past, it was often used in mold manufacturing, industrial design and other fields. Models are now gradually being used for direct manufacturing of some products. [0003] 3D printing technology is based on the computer three-dimensional design model, through the software layered discrete and numerical control forming system, using laser beams, hot-melt nozzles, etc. to accumulate metal powder, ceramic powder, plastic, cell tissue and other special materials layer by layer Bonding, and finally overlaying and molding to create a solid product. 3D printing turns a three-dimensional entity into several two-dim...

AI Technical Summary

Problems solved by technology

The stepping motor used to extrude materials will generate a lot of heat during the working process. If the heat is not dissipated in time, the working performance of the stepping motor will be reduced, which will affect the extrusion volume of the molten material, and then affect the molding accuracy.

However, adding a cooling device to the 3D printer will cause the structure of the 3D printer to be complicated and the cost will increase, which is not conducive to the popularization and use of the 3D printer.
