On the applicability of selective laser melting on pistons for the oil & gas industry: Fatigue limit and fracture toughness of selective laser melted TI6AL4V

Pistons for reciprocating compressors for industrial applications are often made of specialised materials. These prove to have problems with manufacture due to the high quality and short production times needed in combination with a low production volume per design. Additive manufacturing, specifically selective laser melting, could solve the...

Fatigue Crack Propagation in Additively Manufactured and Functionally Graded Inconel 718

Additive Manufacturing (AM), commonly known as 3D printing, exemplifies the recently emerging processing methodologies that aim to substitute the conventional routes, such as to produce parts with complex geometries and eliminate expensive tooling. AM also allows high degree of freedom and rapid prototyping for functional part optimization. This...

Fatigue Behaviour of functionally graded Inconel 718 manufactured by selective laser melting

Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...

The effect of post process treatments on biomechanical properties of Ti6Al4V metamaterials and spinal cage implants manufactured by selective laser melting

Selective laser melting (SLM) is an additive manufacturing technique, which is currently on the rise of being used for manufacturing bone implants. Spinal cage, dental and hip implants can for example be manufactured using SLM. Ti6Al4V lattice structures, categorised as metamaterials, can be printed by SLM with mechanical properties close to...
