Abstract Components produced by additive manufacturing (AM) via direct metal laser sintering (DMLS) have typical as-fabricated surface defects. As a result, properties of AM products should be modified to increase their strength, anti-wear behaviour, and at the same time ensure high corrosion resistance. Surface modification shot peening is considered suitable for medical devices made 17-4PH st...

The introduction of Additive Manufacturing (AM) is changing the way in which components and machines can be designed manufactured. Within this context, designers are taking advantage possibilities producing parts via addition material, defining strategies, exploring alternative design or optimization solutions (i.e., nonviable using subtractive technologies) critical (e.g., gears shafts). Howev...

In this paper, the microstructure, defects, hardness, and tensile strength of 17-4PH specimens manufactured additively using selective laser melting (SLM) technique were studied. The analyzed parts (10 mm size cubic specimens) with different defocus parameter values (−1, 0, +1 mm) in order to evaluate effect a low power (38 W). study was carried out on three sections each specimen, one perpendi...

In this study, we focus on making a double-sided metal plate with an internal structure, such as honeycomb. The stainless steel powder was used in the metal injection molding (MIM) process. The preliminary studies were carried out for the measurement of the viscosity of the stainless steel feedstock and for the prediction of the filling behavior through Computer Aided Engineering (CAE) simulati...

Additive manufacturing (AM) is one of the most trending technologies nowadays, and it has potential to become disruptive for manufacturing. Academia industry pay attention AM because enables a wide range new possibilities design freedom, complex parts production, components, mass personalization, process improvement. The material extrusion (ME) technology metallic materials becoming relevant eq...

This talk presents the simple fabrication and experimental characterization of an energy-efficient hybrid anti-icing coating. The multi-layered coating consists electric heating film with a SiO2 / polydimethylsiloxane (PDMS) superhydrophobic top is composed thin layer copper-based epoxy, insulated in PDMS film. was applied to 17-4PH stainless steel substrate by sequential spray-coating process....
