Abstract

The scaffolds with an open porous structure are one of the most important components for successful tissue regeneration, which can provide 3-dimensional space and biocompatible surfaces for favorable bone ingrowth. Fundamentally, the mechanical properties and biological functions of these porous scaffolds are strongly affected by their porous structure, such as porosity, pore size, interconnections between the pores. Thus, considerable effort has been made to develop new techniques for the production of porous scaffolds with a controlled porous structure, including sponge replication, freeze casting, direct foaming techniques, vacuum-assisted foaming of a ceramic suspension and solid freeform fabrications (SFFs). This paper reviews the operation principle and application of various state-of-the art SFFs, which can create porous scaffolds with an arbitrary geometry, as well as a tightly controlled porous structure.
