Abstract
Methods and devices for additive manufacturing of workpieces are provided. For analysis during production, a test is carried out using a selected test method. The test results are compared with simulated test results derived during a simulation of the manufacturing and testing. The test may use one or more of a laser ultrasound test unit, an electronic laser speckle interferometry test unit, an infrared thermography test unit, or an x-ray test unit.
Claims14
A method for additive manufacturing, the method comprising:
- obtaining manufacturing data for a workpiece, wherein the manufacturing data defines a plurality of layers of the workpiece;
- simulating additive manufacturing of the workpiece using the manufacturing data, thereby creating a simulated workpiece having a plurality of simulated layers;
- simulating measurement of the plurality of simulated layers in order to determine simulated test results for the workpiece;
- physically producing a set of layers of the plurality of layers using an additive manufacturing process according to the manufacturing data;
- measuring the produced set of layers in order to obtain measured test results for the workpiece;
- evaluating the measured test results using the simulated test results to determine whether manufacturing is acceptable;
- in response to the evaluating indicating acceptable manufacturing, repeating the physically producing, the measuring, and the evaluating for further sets of layers of the plurality of layers;
- and
- in response to the evaluating indicating unacceptable manufacturing, performing a remedial measure.
A device for additive manufacturing, the device comprising:
- a simulation device configured to:
- simulate additive manufacturing of a workpiece and
- simulate test results during manufacturing in order to determine simulated test results for the workpiece;
- a manufacturing device configured to perform additive manufacturing of the workpiece layer by layer;
- and
- a test device configured to test the workpiece during the additive manufacturing in order to obtain measured test results,
- wherein the test device is configured to test the workpiece during manufacturing in order to determine measured test results and
- wherein the simulation device is configured to
- evaluate the measured test results using the simulated test results and
- perform a remedial measure in response to the evaluation indicating unacceptable manufacturing of the workpiece.
