Investigation on rapid prototyping of functional porosity gradient parts

The objectives of this project are to design and fabricate scaffolds with porosity gradient and to analyze the mechanical properties of porosity graded scaffolds compared to uniformly porous scaffolds. Selective Laser Sintering (SLS) is used to build the scaffold using Polycaprolactone (PCL). PCL...
