3DDual scanner 3D printer using selective laser sintering

摘要

The present invention relates to a dual scanner 3D printer using selective laser sintering, and more particularly, by applying the dual scanner, it is possible to significantly reduce the manufacturing tack time of the three-dimensional structure, and the irradiation range of each scanner in applying the dual scanner It relates to a dual scanner 3D printer using selective laser sintering that can make the entire building bed without interfering with each other, reduce manufacturing cost and efficiently arrange scanners by using one f-theta lens in common. The dual scanner 3D printer using the selective laser sintering of the present invention is a building bed in which a three-dimensional structure is laminated by selective laser sintering, a material supply unit supplying a powder material to the building bed, and a powder material of the material supply unit while pushing the powder material to the building bed. A lamination module including a recoater module for forming a powder layer of a certain thickness and a recovery unit for recovering the remaining material after forming the powder layer, a laser source for supplying a laser for the selective laser sintering, and the laser source In order to sinter the laser to be stacked according to the shape of the three-dimensional structure to be laminated, it includes a dual scanner module in which two scanners are installed to convert the path of the laser and irradiate it to the building bed. According to the dual scanner 3D printer using the selective laser sintering of the present invention, it is possible to significantly reduce the tact time for the lamination of the three-dimensional structure, and the irradiation range of the dual scanner can be made to the entire building bed without mutual driving interference, By using one f-theta lens in common, manufacturing costs can be reduced and scanner placement can be made more efficient.
