Design and Manufacture of Polymeric Scaffolds

Scaffolds are porous materials designed for organ replecement, which are manufactured with a shape and mechanical properties matched to that of original tissue. Such structures are sieved with cells, genes and proteins, that grow in the scaffold pores and after maturation may be implanted into the body. Scaffolds described in this paper are biodegradable and were fabricated from polylactide by three groups of technology: batch foaming and extrusion foaming, electrospinnig, moreover the microstucture was designed first with CAD technique, then fabricated by means of a rapid prototyping. Microstructure of scaffold was evaluated by the scanning electron microscopy.
