Abstract: A method of producing a three-dimensional object from an extrusion of material forms uses a movable portion of an additive extrusion printing device to form at least one line of material (“line of material”). The printing device preferably extrudes the material as a function of a nominal model having a specification of the object. The method also measures, using a coordinate measuring machine, at least one dimension of the line of material after starting to extrude the line of material. During or after measuring, the method checks, using a checker operatively coupled with the coordinate measuring machine, the dimensional accuracy of at least one dimension of the line of material by comparing the at least one dimension with at least one specification of the nominal model of the object.

Abstract: An apparatus for producing an object has an additive printing device for producing a three-dimensional object in a plurality of layers, and a measuring device for measuring the object during the printing process. The apparatus also has a controller operatively coupled with the measuring device. The controller is configured to control the measuring device to measure the object at one or more prescribed points in the printing process (i.e., before the object is manufactured).
