    EXTRUSION PRINTING OF BIOCOMPATIBLE SCAFFOLDS

    Compositions and methods for making biocompatible articles are provided. A method includes preparing a 3D printable mixture and depositing successive layers of the mixture in a predetermined pattern to form a porous biocompatible article. The predetermined pattern has a porosity suitable for a bone or cartilage scaffold. Associated 3D printable compositions and porous articles made from the described methods are also described. The preparing a 3D printable mixture can comprise conjugating an alkyne-terminated polymer to a peptide to form a peptide-containing composite, or providing a mixture that comprises a ceramic material and a binder, and wherein the 3D printable mixture comprises from 50 wt. % to 80 wt. % of the ceramic material.
