摘要： A method for producing a dental prosthesis includes preparing three-dimensional data on the dental prosthesis, preparing a processing target that transmits laser light, setting processing points representing an outer shape of the dental prosthesis based on the three-dimensional data, setting a to-be-cut plane extending from a surface of the processing target to the processing points, creating the processing points in the processing target by irradiating the processing target with the laser light, and cutting a portion of the processing target that is outward of the dental prosthesis with an internal stress by irradiating the processing target with the laser light along the to-be-cut plane.

摘要： A method of producing a projection path data to be used in forming a desired shape by projecting a laser beam into a material, the method includes a first step of converting two-dimensional information representing the desired shape in two dimensions in an XYZ coordinate system into three-dimensional information in an XYZ coordinate system, and a second step of producing the projection path data based on the three-dimensional information that has been converted.

摘要： A processing method for forming an object by processing a material using a cutting tool and a laser beam, including forming, by projecting the laser beam to an unnecessary portion of the material, one or more cleavage regions in the unnecessary portion, and cutting, using the cutting tool, the unnecessary portion including the one or more cleavage regions that have been formed.

摘要： In a laser processing method for processing an interior of a material by projecting a laser beam, in which the material is placed in a container filled with a liquid with a refractive index equivalent to a refractive index of the material, at least a portion of the container defines and functions as an incident surface with a certain curvature, and the laser beam is projected to a corrected position through the incident surface, the corrected position having been obtained based on the refractive index of the material and a processing position in the material.

摘要： A processing method includes irradiating a processed portion of a light-transmittable material with laser light, and removing an unnecessary portion to form an object. When there are layered processed portions in an emission direction of the laser light, the layered processed portions are irradiated with the laser light in order from the processed portion farthest from a surface of the material which the laser light enters.
