A method for heating a base material in additive manufacturing includes a) providing an energy beam for the heating of the base material, wherein the base material is arranged to at least partly form a manufacturing plane, and b) irradiating the manufacturing plane for the heating with the energy beam under scaled irradiation parameters, wherein the scaled irradiation parameters are derived in that irradiation parameters for fusing the base material are scaled by a scaling factor, and wherein the scaling factor includes a quotient of a heating beam diameter and a fusion beam diameter.

A method and apparatus for designing and manufacturing a component in a computer-aided design and manufacturing environment is disclosed. A method includes obtaining a geometric model of a component from a geometric model database, and determining at least one orientation parameter value associated with the geometric model of the component. The at least one orientation parameter value is associated with an orientation parameter that defines orientation of the component during additive manufacturing of the component. The method includes performing volumetric analysis of the component based on the at least one orientation parameter value associated with the component using the geometric model of the component. The method also includes computing one or more overheating areas in the component corresponding to the at least one orientation parameter value based on the volumetric analysis of the geometric model of the component, and outputting a multi-dimensional visual representation of the geometric model of the component Indicating one or more overheating areas in the component.

A computing system may include an access engine and a defect detection engine. The access engine may be configured to access a slice contour of a given layer of a 3-dimensional (3D) object designed for manufacture through an additive manufacturing process and obtain hatch tracking for the slice contour, the hatch tracking representative of an energy path to melt metal powder for constructing the given layer through the additive manufacturing process. The defect detection engine may be configured to construct, from the slice contour, an as-built image for the given layer by rendering the hatch tracking in the slice contour; construct, from the slice contour, an idealized image for the given layer; and identify defects in the given layer via image analysis between the as-built image and the idealized image.

An irradiating method for the additive production of a component in order to heal structural defects in an additively constructed structure for the component. The method includes the providing of a laser or electron beam and the selective irradiating of a defect region of an additively constructed layer of the structure by the laser or electron beam according to a predetermined, in particular closed trajectory, which defines the defect region, wherein the defect region contains a structural defect. A method for additive production, a correspondingly produced component and a computer program product utilize the method.
