3D printing of novel hydrogel containing bone implants

Betreuer: Dr. R. Detsch, Prof. Dr.-Ing. habil. Aldo R. Boccaccini

Additive manufacturing (AM) techniques can be used to generate scaffolds for the replacement or repair of damaged or diseased human tissue or organs. There are different AM techniques which are used commonly, whereas one of the most popular ones is 3D bioplotting [1]. With this technique a wide range of different materials are printable, even hydrogels. Over the last decades hydrogels have revealed great potential in the field of medicine. They build, through the absorption of water, a soft structure, which can be printed also in combination with cells in biofabrication approaches [2]. Due to their excellent biological properties, hydrogels are applied in this project to develop new biomedical devices. The aim of the project is to develop an implant that replaces damaged bone through the combination of hydrogels with different rigid or hard materials.This project is a collaboration of the Institute of Biomaterials with industrial and academic partners.
