The present invention relates to an apparatus and a method for geometrical verification of three-dimensional objects during manufacturing of the objects. The manufacturing process comprises applying successive layers based on a digital 3D design model of the object, and causing each of the layers to fuse after applying the layer. The verification method comprises repeatedly for each layer recording one or more images of the present layer, creating a digital 3D disk model of the present layer based on said one or more images, creating a digital 3D copy of the object being manufactured based on the 3D disk model of the present layer and 3D disk models of previous layers, and verifying the geometry of the object being manufactured based on the 3D copy of the object being manufactured and the 3D design model of the object. |
