This paper presents an overview of the selective laser sintering (SLS) process of various materials. The influence of distinct scanning patterns and SLS process input parameters (e.g.: scanning rate, laser power, hatching distance) on the sintered materials’ physical and technological properties was investigated. The classifications of SLS processes and scanning patterns were also presented. The literature survey revealed that sintered materials’ density, shrinkage and dimensional accuracy are significantly affected by the scanning strategy, as well as selection of hatching distance and line energy. The research results presented in this work can be also applied to the appropriate selection of the SLS process strategy, enabling the improvement of sintered materials’ physical and technological properties.

W pracy dokonano przeglądu literaturowego, dotyczącego technologii selektywnego spiekania laserowego. Zaprezentowano wyniki badań dotyczące wpływu strategii oraz parametrów wejściowych procesu (np.: prędkości wiązki lasera, mocy lasera, odległości pomiędzy ścieżkami wiązki) na właściwości fizyczne i technologiczne otrzymanych spieków. Dokonano również klasyfikacji procesów SLS i niezbędnych do ich realizacji strategii. Przegląd literatury ukazał, że gęstość, skurcz oraz dokładność geometryczna spieków w istotnym stopniu zależą od doboru strategii, odległości pomiędzy ścieżkami wiązki lasera i energii liniowej. Wyniki badań zaprezentowane w pracy mogą również stanowić punkt wyjścia do dalszych badań, dotyczących poprawy właściwości fizycznych i technologicznych wytwarzanych spieków.
