Abstract<\/em>.<\/strong> In Selective Laser Melting (SLM) technology a high-energy laser deposits metal powder layer-by-layer onto a building platform. High geometric accuracy in SLP is critical to producing high-quality parts. Modern calibration methods require significant manual labor, major equipment modification, or the use of expensive auxiliary equipment. This paper presents a new technique for calibrating galvanometer mirrors for SLP technology using an external camera. The proposed approach allows to simplify, cheapen and automate the calibration process.<\/p>\n\n\n\n
