Method of providing a dataset for the additive manufacture and corresponding quality control method
A method of providing a dataset for additive manufacturing includes collecting a first type of data for the dataset during the additive buildup of a at least one layer of a component to be manufactured, evaluating of the structural quality of the layer by the first type of data, modifying the first type of data in that fractions of the data representing an insufficient structural quality of the layer are deleted from the first type of data, and superimposing second type of data, to the first type of data, wherein the second type of data is suitable to support a validation of the structural quality of the as-manufactured component.
1. A method of providing a dataset for additive manufacturing comprising:
collecting a first type of data for the dataset during an additive buildup of at least one layer of a component to be manufactured,
evaluating a structural quality of the layer by means of the first type of data,
modifying the first type of data in that fractions of the data representing an insufficient structural quality of the layer are deleted from the first type of data,
wherein an algorithm captures regions of unsolidified or erroneously solidified powder in a powder bed in each layer for the component,
superimposing a second type of data, to the modified first type of data, wherein the second type of data is suitable to support a validation of the structural quality of an as-manufactured component, and
superimposing a third type of collected data on the modified first type of data,
wherein the second type of data and/or the third type of data are toggleable on and off in a data processing device to validate the structural quality of the as-manufactured layer of the component.
2. The method according to claim 1 ,
wherein the first type of data comprises optical or image data, microscopical data, CAD-data including geometrical information, CAM-data and/or numerical control data of or for the layer.
3. The method according to claim 1 ,
wherein the second type of data and/or a further type of data comprises temperature, pressure or gas flow information, or information about beam properties or about a melt pool or powder bed, collected or read out from a manufacturing device or a further sensor devices of or for the layer.
4. The method according to claim 1 ,
wherein the dataset is a graphical and/or a tomographical 3D-data set of the as-manufactured component.
5. The method according to claim 1 ,
wherein a coloured, textured or otherwise graphically enhanced 3D representation of the dataset is generated.
6. The method according to claim 1 ,
wherein the different and/or superimposed types of data are subjected to correlation algorithms, and/or with the aid of mathematical models, and wherein correlated information is in turn put into machine learning algorithms.
7. A quality control method for the additive manufacture of a component comprising:
providing a dataset according to the method of claim 1 ; and
validating the structural quality of the as-manufactured component based on the provided dataset.
8. The method according to claim 1 , further comprising: additively manufacturing the component.
9. The method according to claim 1 , further comprising:
validating the structural quality of the as-manufactured component based on the dataset.
10. A method of additive manufacturing a component, applying the method of providing the dataset according to claim 1 .
11. A method of additive manufacturing a component, applying the quality control method according to claim 7 .
