Chain extension and coupling enable the synthesis of novel bio-polymer systems that show logically-tailored properties. Accordingly, families of thus synthesized linear polyesters, bio-based polycarbonates and renewable, fatty acid based polyamides will be introduced. Tailored degradation mechanisms will be presented, including rapid enzymatic degradation of bis-oxazoline chain extended polycaprolactone and surface erosion of poly(ester-anhydrides). A novel family of CO<sub>2</sub> –derived and bio-based poly(propylene carbonate) will be presented.<br/>Bioactivity can be achieved through the addition of bio-active functional groups, like in the case of biotinylated PLA-microparticles and poly(ester-co-depsipeptides). Alternatively, bioactive fillers or fibers can be added to the composition.<br/>Photocuring functionalities of the above mentioned bio-polymers enable fast liquid-to-solid transition, which is crucial in stereolitography. Examples of 3D-designed and manufactured polymeric scaffolds for biomedical applications will be presented.
