Novel 3D printer and using method thereof

Abstract

The invention discloses a novel 3D printer. The novel 3D printer comprises a pedestal, a top cover, a printing head base, a printing head and a laser assembly, wherein the printing head is installed on the printing head base. The pedestal is connected with the top cover through a stand column in an assembled mode, the printing head base is connected with the stand column through a moving mechanism, the laser assembly is installed on the printing head base, and the focal point of a laser beam emitted by the laser assembly is located at a print material outlet in the printing head. According to the novel 3D printer, the novel 3D printer is used for achieving a FDM printer, the printing head and the laser assembly are installed together, so that the printing head and the laser assembly move together, and meanwhile the focal point of laser emitted by the laser assembly further needs to be aligned with a print material extruding end of the printing head; and an SLA printing technology can be achieved on the structure of an existing FDM printer, a complex optical system is not needed, meanwhile the printing precision and the price are guaranteed, and high cost performance is achieved.

Description

technical field [0001] The invention relates to the technical field of 3D printers. Background technique [0002] Among the existing 3D printers, the main implementation schemes are as follows. The first is the stereolithography technology SLA, which uses laser to solidify the liquid printing material. The second is the melting and extrusion of the printing material directly. Deposition technology FDM, the printing technology of the first scheme has high printing accuracy, but it needs to be equipped with a professional optical system, which is expensive. The second printing accuracy is relatively low, but the structure is simple, no complicated optical system is required, and the price is cheap. [0003] In view of the advantages and disadvantages of the above two conventional printing technologies, a new type of printer is required in the field of 3D printers, which can simultaneously combine the advantages of the two printing technologies.
