The use of modern 3D technologies in expert activities significantly contributes to improving the quality of conducted research while substantially reducing time costs. The paper examines the possibilities of using the "Calibri Mini" 3D scanner under various weather conditions (obtaining three-dimensional models of volumetric traces outdoors in natural daylight (bright sun, cloudy weather) during summer and winter periods). Testing the "Calibri Mini" 3D scanner in "field conditions" demon strated its effectiveness at low temperatures from 0 to +5 °C below the manufacturer's stated range. Using a shading device for 3D scanning to record volumetric traces of footwear and vehicle tires positively affects the quality of the obtained polygonal 3D models. The results of the work will allow forensic units to use the "Calibri Mini" 3D scanner at crime scenes to capture volumetric traces and obtain three-dimensional polygonal models in order to improve forensic records and further study them.
