3D modeling device and 3D modeling method for supplying material with high precision

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 modeling material and a step of removing the subsidiary material to form a 3D object formed of the modeling material, said method further comprising:

• supplying the subsidiary material in the form of dots constituting the subsidiary material layer, wherein the subsidiary material is deposited drop by drop and is discharged to drop onto a predetermined position;
• supplying a light-curing resin in the form of dots as the modeling material constituting the modeling material layer, wherein said supplying of the light-curing resin in the form of dots comprises depositing the light-curing resin in the form of dots at spaced intervals from one another and then depositing the light-curing resin in the form of dots within spaces between the spaced intervals;
• and
• irradiating the supplied dot-shaped light-curing resin with light,
• wherein the light is irradiated at an elevation beneath a position where the light-curing resin is discharged, 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.

A 3D modeling method comprising:

• forming a subsidiary material layer by depositing a subsidiary material and cutting the subsidiary material, wherein the subsidiary material is deposited drop by drop;
• forming a model material layer on the subsidiary material by depositing a light-curing resin as a modeling material, wherein said depositing of the light-curing resin includes depositing drops of the light-curing resin at spaced intervals from one another and then depositing drops of the light-curing resin within spaces between the spaced intervals;
• irradiating the light-curing resin with light;
• and
• 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 deposited as drops, and
• 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.
