International Classification:

G01M 11/00
B29C 64/153
B22F 3/105
B29C 64/273

Abstract:

A testing apparatus for use with a laser powder bed fusion additive manufacturing device that includes a laser for generating a non-stationary laser beam and a build plane positioned at a predetermined location relative to the non-stationary laser beam. The portable testing apparatus includes a support having an upper surface adapted to receive and absorb laser light generated by the non-stationary laser beam; a plurality of pin-hole defining structures each positioned to receive the laser light generated by the non-stationary laser beam, and such that each pin-hole is elevated at a predetermined height above the upper surface of the support and parallel thereto; a fiber optic cable disposed within each pin-hole defining structure, wherein each fiber optic cable has a proximal end at which the laser light is received through the pin-hole and a distal end to which the laser light is delivered; and a photodetector located at the distal end of each fiber optic cable, wherein the photodetector converts the laser light delivered to the photodetector into electrical voltage output signals based on intensity of the laser light received through each pin-hole.
