POSITIONING SYSTEM FOR AN ADDITIVE MANUFACTURING MACHINE

Abstract:

An additive manufacturing machine (900) including a build unit (904) that is supported by an overhead gantry (912) and a method for positioning the build unit (904) are provided. A positioning system (930) includes one or more position sensors (932) that are separate from the build unit (904) and are configured for obtaining positional data of the build unit (904). The positioning system (930) may continuously track the position and orientation of the build unit (904) and the additive manufacturing machine (900) may adjust the position of the build unit (904) toward a target position.
