AN OVERVIEW OF SELECTIVE LASER SINTERING TECHNOLOGIES
Journal Title: Archives of Mechanical Technology and Materials - Year 2015, Vol 35, Issue
Abstract
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.
