Scaffold fabrication techniques solvent casting

The authors described several other fabrication techniques, but their conclusions are the important parts of their report Conventional scaffold fabrication techniques are incapable of precisely controlling pore size, pore geometry, spatial distribution of pores and construction of internal channels within the scaffold. They also state that scaffolds produced by the solvent casting-particulate leaching technique cannot guarantee interconnection of pores because interconnection is dependent on whether the adjacent salt particles are in contact. Moreover, only thin scaffold cross sections can be produced due to difficulty in removing salt particles deep in the matrix. 

There are mainly four fabrication techniques that can produce 3-D composite scaffolds with highly interconnected pores thermally induced phase separation, solvent casting, rapid prototyping, and microsphere sintering.
