Abstract:
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.
