Abstract:
1. A 3D modeling method comprising: a step of repeatedly cutting a subsidiary material layer formed of a subsidiary material and cutting a modeling material layer formed of a light-curing resin as a modeling material; a step of irradiating the light-curing resin with light; and a step of removing the subsidiary material to form a 3D object formed of the modeling material, wherein at least one of the subsidiary material constituting the subsidiary material layer and the modeling material constituting the modeling material layer is supplied in the form of dots, wherein the light is irradiated at an elevation beneath a position where the light-curing resin is discharged during depositing thereof, wherein the light is irradiated from a light guide member, wherein the light-curing resin is discharged from an outlet of a dispenser, and wherein the outlet of the dispenser is provided within a hole in the light guide member, wherein the light guide member includes a plurality of optical fibers having tip ends positioned around and lower than the outlet of the dispenser, and wherein said tip ends are provided in a ring around the outlet of the dispenser.
