Biodegradable synthetic resin replaces vital body parts

Researchers at the University of Twente (UT) have developed a new type of resin that can be broken down by the body. This new resin makes it possible to replicate important body parts exactly and make them fit precisely.

The resin can be given different properties depending on where in the body it is to be used. Cells can be sown and cultured on these models, so that the tissues grown are, in fact, produced by the body itself. The new resin has been developed by Ferry Melchels and Prof. Dirk Grijpma of the UT’s Polymer Chemistry and Biomaterials research group. An article on this breakthrough will be appearing in the authoritative specialist journal, Biomaterials.

Stereolithography is a technology with which three-dimensional objects can be made from a digital design. It is also possible to scan an object using a CT scanner (or micro-CT scanner) to obtain a digital image. The object in question can subsequently be copied extremely accurately with a stereolithograph. A stereolithograph is therefore a 3D replicating machine with a very high resolution. The way it works is based on the local hardening of a liquid resin with computer-driven light. The resins available for stereolithography so far harden into chemical networks that cannot be broken down.
