Mechanical behaviour of 3D printed ordered pore topological iron scaffold

This paper deals with the development of a five-step rapid manufacturing technique for iron scaffold fabrication based on micro-extrusion-based 3D printing and pressureless microwave sintering. Two different pore morphology structures were fabricated with similar strut and pore sizes. Further, the m...

Description
Summary:This paper deals with the development of a five-step rapid manufacturing technique for iron scaffold fabrication based on micro-extrusion-based 3D printing and pressureless microwave sintering. Two different pore morphology structures were fabricated with similar strut and pore sizes. Further, the mechanical properties of the fabricated scaffolds were evaluated. •Novel manufacturing route to fabricate OPTS of iron by using micro-extrusion-based 3D printing and pressureless microwave sintering.•Different unit cell-based iron scaffolds with 31- 60.22 % porosity were fabricated.•Maximum Young’s modulus of 370 was obtained.
