Biodegradable PUs can be processed into various products such as freeze-dried foams [67], electrospun fibers [115], and 3D-printed scaffolds [68], by the use of solvent or heat. In the case of thermal processing, the moisture must be removed to avoid heat-induced hydrolysis [72], Biodegradable PU has been used as scaffolds for the repair of bones, cartilages, and blood vessels [68,116,117], demonstrating the potential in a wide range of medical applications. [Pg.156]

For example, stereolithography can be used. It is a liquid-based technique that utilizes LBL curing of a photosensitive hydrogel precursor solution by means of a laser. Alternatively, nozzle-based systems are applied. They process the material chemically as it passes through the nozzle (ink-jet printing, 3D printing cf. Section 3.10). Cells and biomolecules can be simultaneously printed with the scaffold material [79]. [Pg.90]

Need of multifunctionality and to minimise invasive surgery should contribute to the development of intelligent or smart biomaterials in future which are able to respond to light, temperature, pH, etc. In this regard, PTMC-based terpolymers with shape memory properties present great interest for potential apphcations. Moreover, the development of new processing techniques, in particular computer-assisted 3D printing, makes it possible to achieve devices or scaffolds with complex architectures such as coronary stents or atrial septal defect occluders. [Pg.140]
