Abstract
A printable biodegradable polymer composite includes PGSA, a biodegradable photo-initiator and material selected from the group consisting PCL-DA and PEG-DA uniformly blended together. By adjusting the blending ratio, the elasticity, mechanical properties and degradation patterns may be adjusted for producing a tissue, organ or related bio-product by 3D-printing.
