description: In this paper, we are studying the process of direct laser growth and methods of measuring the quality of focusing of a gas-powder stream. As part of this work, a portable and compact device was developed to allows you to quickly and accurately measure the capture coefficient of the powder. In the course of the work, tasks such as were solved: 1. The studying and analyzing of existing methods for measuring the coefficient of captured powder. 2. Based on the gained knowledge were select the appropriate measurement technique for the development of the device. 3. The assortment of components, and formulation of the requirements and parameters of the measuring device for its effective operation and using. As a result of the work, a device was designed and assembled that suits the previously set requirements and allows to measure the powder capture coefficient with sufficient accuracy.
