Abstract
Method of manufacturing a three-dimensional object according to which the object is built layer-wise by solidification of a building material, wherein a test specimen is built which is excited to oscillate after being built and wherein natural frequencies of the oscillations are determined.
Claims18
Method of manufacturing a three-dimensional object according to which the object is built layer-wise from a building material to be solidified, comprising:
- building a test specimen on a removable building platform or at or on the object to be produced,
- exciting the test specimen to mechanical oscillations on the building platform or on the object after the building,
- determining natural frequencies of the oscillations of the test specimen, and
- determining material properties of the object to be produced from the determined natural frequencies of test specimen.
