Additive Manufactured Nanocomposites for Bone Tissue Engineering Applications: an Overview

Tissue Engineering aims to repair, regenerate or restore damaged tissues. Structures known as scaffolds can be manufactured in different ways and with various materials such as synthetic and natural polymers as well as inorganic materials. Additive Manufacturing (AM) has been used to produce porous scaffolds. Particularly, Selective Laser Sintering (SLS) produces materials and composites through a selective solidification of a variety of fine powders. AM-made biomaterials may be suitable for different affected or injured parts by stimulating the biological system around the implant. The present work aims to review relevant concepts concerning the nanostructure for regeneration of the bone tissue when in contact with the native tissue, as well as the suitable techniques and materials to fabricate it.
