Abstract
An additive manufacturing method supporting layer by layer testing includes a layer test including generating a hammer beam using laser light having a first wavelength, generating a read-out beam using laser light having a second wavelength, directing the generated hammer beam toward a first layer on a part to provide an acoustic hammer pulse that induces surface movement of the part, and reading the surface movement of the part using the read-out beam directed to a second position on the part. Layers can be added and the layer test repeated.
