Assess and characterise the suitability of a novel silk reinforced biphasic 3D printed scaffold for osteochondral tissue regeneration. Biphasic hybrid scaffolds consisted of 3D printed poly(ethylene glycol)-terephthalate-poly(butylene terephthalate)(PEGT/PBT) scaffold frame work (pore size 0.75mm), which has been infilled with a cast and freeze dried porous silk scaffold (5×5×2mm3), in addition to a seamless silk top layer (1mm). Silk scaffolds alone were used as controls. Both the biphasic and control scaffolds were characterised via uniaxial compression testing (strain rate 0.1mm/min), and the potential biocompatibility of the scaffolds was tested via in vitro culture of seeded bone marrow stromal cells post fabrication.Abstract
