Bioplotting hybrid scaffolds – 3D printing smart structures. Image credit: EnvisionTEC Dr. qing li and a team of scientists recently completed a study investigating the compatibility of hydroxyapatite and collagen when used for 3D bioprinted scaffolds that serve as bone substitutes. 3D printing is the future of repairing bone trauma and defects because it can manipulate the biocompatible materials and live tissues into the organic geometries necessary to stimulate cellular bone growth; bone is porous and 3D printing can replicate that porosity. Li and the team of researchers worked with two types of hydroxyapatite (HA), a mineral that makes up most of the inorganic matter in tooth enamel and bones. Function of the 3D-Bioplotter System as demonstrated at Rapid 2015. Credit: Mary Ann Liebert, Inc. Nano hydroxyapatite (nHA) and deproteinized bovine bone (DBB) were each mixed with collagen (CoL) to create two bio-inks for 3D printing with an EnvisionTEC […]
