Influence of laser sintering parameters on mechanical properties of polymer products

With Additive Manufacturing - AM it is possible to create physical models, prototypes, components, tools and functional parts from 3D data constructed using the computer (CAD), with complicated geometry, which is very difficult or even impossible to do with other manufacturing technologies. AM processes for the manufacturing of prototypes use metals, ceramics and polymers in the form of liquids, powders, wire, foil, etc. However, there are many limitations, primarily in the selection of materials. Therefore, it is necessary to know the material properties, and how the various parameters of the machine influence on them, especially if it is manufacturing functional parts. The paper provides a brief overview of Selective Laser Sintering – SLS, and how the machine parameters (layer thickness, speed and power of laser) influence the mechanical properties of materials (tensile properties and hardness).
