Abstract: A part defect testing system includes a hammer beam system that provides laser light having a first wavelength. A read-out beam system provides laser light having a second wavelength. A control system is used to direct the generated hammer beam laser light toward a first position on a part to provide an acoustic hammer pulse that induces surface movement of the part. An areal camera is arranged to produce an interferogram derived from reading surface movement of the part using the read-out beam directed to a second position on the part.

Abstract: A method of additive manufacture is disclosed. The method may include providing a powder bed and directing a shaped laser beam pulse train consisting of one or more pulses and having a flux greater than 20 kW/cm 2 at a defined two dimensional region of the powder bed. This minimizes adverse laser plasma effects during the process of melting and fusing powder within the defined two dimensional region.

Abstract: An apparatus includes at least one laser source and a print bed. A light valve array having at least three optically addressable light valves is positioned to direct differing images at the print bed. Optics to direct multiple beams derived from the at least one laser source can be positioned to direct light toward and from the optically addressable light valves.

Abstract: An additive manufacturing system can include at least one laser source and a speckle reduction system that receives light from the at least one laser source. The speckle reduction system provides laser light to an optical homogenizer that increases uniformity of laser light and can provide the light to an area patterning system.
