The widespread use and implementation of selective laser melting (SLM) technology entails active development in this area, especially for parts with complex internal circuits used in aircraft manufacturing. In this technology, a continuous laser source is usually used as a radiation source. Along with all the advantages, this technology has a number of detrimental features and disadvantages that can be avoided by using a pulsed laser. In this study, the AISI 316L steel was selected as the powder. The possibility of creating tracks by pulsed selective laser melting was examined with a focus on determining the parameters that had the highest impact on the process of object formation. The analysis of the experimental studies carried out by this method showed that the main parameters affecting the track size were the pulse duration and instantaneous radiation energy. The calculated mathematical model made it possible to establish the basic dependences and present the optimal range of parameters to achieve the predicted processing result. |
