Quality of AM implants in biomedical application

Additive manufacturing (AM) technologies, particularly those based on powder bed fusion (PBF), most notably, selective laser melting (SLM) for metals, have in recent years emerged as unique fabrication methods for patient-specific implants made of metals and their alloys. The ability to manufacture complex geometries together with the other...

Corrosion fatigue behavior of additively manufactured biodegradable porous iron

The corrosion fatigue behavior of additively manufactured topologically ordered porous iron based on diamond unit cells was studied for the first time to understand its response to cyclic loading in a simulated physiological environment. The material exhibited high fatigue resistance with fatigue strengths being 70% and 65% of yield stress in...

Effect of porosity variation strategy on the performance of functionally graded Ti-6Al-4V scaffolds for bone tissue engineering

Functionally graded scaffold (FGS) is designed to mimic the morphology, mechanical and biological properties of natural bone closely. Porosity variation strategy between different regions in FGS plays a crucial role in influencing its mechanical and biological performance. A combination of modeling tool and scripting language can effectively...

Additively manufactured biodegradable porous magnesium

An ideal bone substituting material should be bone-mimicking in terms of mechanical properties, present a precisely controlled and fully interconnected porous structure, and degrade in the human body to allow for full regeneration of large bony defects. However, simultaneously satisfying all these three requirements has so far been highly...
