This symposium will be focused on two types of polymer processing techniques: electrospinning and 3D-printing. One target is to explore emerging technologies in electrospinning set-ups for obtaining polymeric nanofibers and tuning their properties aiming applications in biomedical, drug delivery, enzyme immobilization, environmental, electrical and optical sensors, etc. Another target is related to developing materials for 3D-printing processing. The 3D-printing is a rapid material-manufacturing technique, being proved as a strategic way for joining materials to make objects mimicking 3D model data. Therefore, achievements in development of printable polymers with improved performance for 3D-printing remain as challenges and an opened window. This symposium will provide multidisciplinary point of views mainly in polymeric materials, involving physicists, chemistries, biologists and engineers, looking for new perspectives and future directions on electrospinning and 3D-printing of materials.
