ǂThe ǂinfluence of manufacturing parameters on properties of Ti-6Al-4V products fabricated by selective laser melting, and their surface coating with bioactive polymer
Snehasihis Pal, Igor Drstvenšek, Vanja Kokol
Doktorska disertacija
Oznake: selective laser melting;unidirectional freezing method;laser processing parameters;porosity;microstructure;mechanical properties;
Technological parameters included in energy density (ED) are the more powerful tools in selective laser melting (SLM) technology which can be used in the time of fabrication to regulate chemical, metallurgical, and mechanical properties of a product. The volumetric Energy Density (ED) depends on the ...

It is well known that Selective Laser Melting (SLM) does not provide the same mechanical properties in all directions of the part. This is due to the microstructural grain orientation and pore shape in SLM products. Therefore, depending on the direction of the pressure applied to the SLM product, a ...

In this study, several variations of Ti–6Al–4V β-grains and α′-martensites were observed while changing the combinations of laser parameters and keeping the energy density (ED) constant in the laser powder bed fusion (LPBF) process. Several combinations of laser power, scanning speed, and hatch spac ...
