A METHOD FOR SETTING THE SCAN TRAJECTORY RANGE OF A 3D PRINTER BY USING A LASER

摘要

PROBLEM TO BE SOLVED: To solve the problem in which: in conventional 3D printers by using lasers, unintentional protrusions or uneven stripes appear on the surface of a solid molding object, especially when it has a transparent, smooth shape, so that its utility value as the solid molding object deteriorates.SOLUTION: By making the structure trajectory of the laser uniform and changing the offset from dimensional one to two-dimensional one, unintentional protrusions and uneven stripes are prevented from occurring on the solid molding object. Consequently, the solid molding object can preserve its beauty of appearance even with the transparency increased.SELECTED DRAWING: Figure 5
