Abstract
Study of the possibility for using a laser ultrasonic technique in nondestructive testing of products that are manufactured by selective laser melting is presented. Procedures of producing samples and carrying out nondestructive testing by the laser ultrasonic technique are described. Mechanical properties of samples that were grown in vertical and horizontal directions have been measured, as well as the speed of ultrasound in these samples. It has been established that the laser-ultrasonic technique is a promising technology for the quality control of products that are obtained by selective laser melting.
