Manufacturing method of stereolithography, data creation method of nozzle moving path used therefor, and manufacturing apparatus for three-dimensional molding and data creation program of nozzle moving path used therefor

摘要

Manufacturing method of stereolithography capable of improving the shaping accuracy and forming speed of three-dimensional molding having soft portion, method for producing data of nozzle moving path used therefor, and apparatus for manufacturing stereoscopic material and nozzle shift used therein Provide a data path generating program.A material for forming a hard stereolithography material (20) is discharged from a nozzle to a stage to form an outer shell wall portion (21) which is a part of the outer shell (2) of the three-dimensional shaping material (1), and a soft stereolithography material (30) is surrounded by the outer shell wall portion (21) from the nozzle The process is performed to discharge the inner region to form an inner core portion (31) constituting part of the inner core (3) of the stereolithography (1).Then, a three-dimensional molding (1) having an outer shell (2) formed by an outer shell wall portion (21) laminated in a plurality of steps and an inner core (3) formed by an inner core portion (31) laminated in a plurality of steps is formed.
