Layered gelatin/PLLA scaffolds fabricated by electrospinning and 3D printing- for nasal cartilages and subchondral bone reconstruction

In the present work the advantages of two kinds of different, well known and applicable, biomaterials (PLLA and gelatin) and two kinds of scaffold fabrication techniques (3D printing - FDM and electrospinning) were combined in order to create a novel multifunctional layered scaffold for nasal cartilages and subchondral bone reconstruction. The pore size of scaffolds produced by 3D printing technology was designed to solve the problem that...
