Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A 3D printable biodegradable polymer composite comprising: poly(glycerol sebacate acrylate) 30˜50 wt %; a photo-initiator; polycaprolactone-diacrylate 30˜40 wt %; and polyethyleneglycol-diacrylate 20˜30 wt %; wherein a degree of acrylation of the poly(glycerol sebacate acrylate) is at a range of 5%˜60%. 2. The 3D printable biodegradable polymer composite as claimed in claim 1 , wherein: the photo-initiator is at a range of 0.05˜5 wt %; the photo-initiator is a UV light initiator or a visible light initiator; the UV light initiator is TPO or prefluorinated dipheny titanocene; and the visible light initiator is TPO, prefluorinated dipheny titanocene or camphorquinone.
