A systematic study was performed to explore the feasibility of processing titania powders by selective laser sintering (SLS). In particular, five samples with the same chemical composition, but different particle size distribution have been used. The laser sintering process conditions, i.e. laser power and laser scan speed, were studied as well. Squared well-defined specimens were successfully produced and their internal morphology and mechanical properties were analysed using a scanning electron microscopy and a flexural bending test respectively. The effect of the thermal history during the laser sintering process on the physical properties of the sintered parts was modelled and discussed.

Abstract
A systematic study was performed to explore the feasibility of processing titania powders by selective laser sintering (SLS). In particular, five samples with the same chemical composition, but different particle size distribution have been used. The laser sintering process conditions, i.e. laser power and laser scan speed, were studied as well. Squared well-defined specimens were successfully produced and their internal morphology and mechanical properties were analysed using a scanning electron microscopy and a flexural bending test respectively. The effect of the thermal history during the laser sintering process on the physical properties of the sintered parts was modelled and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
