Abstract: A data generation method includes: generating, based on an input of an input apparatus, model data representing a three-dimensional shape of an object that is additively built on a placement apparatus by using a build head; generating, based on the model data, display data for displaying a three-dimensional model related to the object on a display apparatus; and generating, based on the model data, build data for additively building the object, the three-dimensional model related to the object includes a three-dimensional model of a build object before the additive building is completed, the display data includes interference information indicating an interference between the build head and at least one of the build object and the placement apparatus, when the re-input of the input apparatus is performed, the model data and the display data are re-generated based on the re-input, the interference information is updated based on the re-input.

Abstract: A processing system is configured to form a build object. The processing system includes: a first optical system that condenses an energy beam on a first irradiation position; and a material supply apparatus that is configured to supply build materials to the first irradiation position. The processing system is capable of forming the build object by irradiating the build materials supplied by the material supply apparatus, with the energy beam from the first optical system, and the processing system processes the build object by a second optical system irradiating a surface of the build object with the energy beam from the first optical system.

Abstract: An imaging head includes: a deflection optical system configured to deflect light from at least a part of a melt pool part, the melt pool part is formed on the object by an irradiation with a processing beam from the processing head; an imaging apparatus configured to optically receive the light deflected by the deflection optical system to capture an image of at least a part of the melt pool part; and a supply unit configured to supply gas from a gas supply apparatus to at least a part of an optical surface of the deflection optical system.

Abstract: A data generation method includes: generating model data representing a three-dimensional model of a pipe based on a value of a parameter defining a shape of the pipe designated by a user using an input screen; and setting, as a value of a parameter defining a position of an intermediate part of the pipe, a value of a parameter defining a position away from a position of an edge part of the pipe by a first distance.

Abstract: A processing system includes: an irradiation system that irradiates an object with an energy beam; a material supply member that supplies a build material irradiated with the energy beam; a measurement apparatus that obtains information related to a height of a surface of the object; and a distance change apparatus that changes a distance between the material supply member and the surface based on a measured result by the measurement apparatus.
