ABSTRACTRecently, an inexpensive 3D lithography technique was developed by Professor Nicholas Fang at the University of Illinois where a projector is used in combination with a Microsoft® PowerPoint presentation to expose the liquid negative-tone photoresist 1,6-hexanediol diacrylate in a layer-by-layer fashion. Where Professor Fang initially used this method as a teaching tool, we have used the inexpensive 3D printing technique to create 3D structures of fumarate based polymers. This class of polymers are liquids at room temperature which makes them ideal for the projector based lithography technique when used in combination with the photoinitiator bisphenyl(2,4,6-trimethylbenzoyl)-phosphine oxide (BAPO). Furthermore, the fumarate based materials are biocompatible and are suitable candidates for tissue engineering applications.

3D Printing Technique

The University of Nantes has developed a 3D printing technique (BatiPrint3DTM) dedicated to the construction of the walls of a house. This innovative on site construction technique is based on the deposition of two layers of expansive foam used as a formwork for a third concrete layer. It allows to build at the same time the structure and the insulation. This new construction technology has first been developed at the laboratory, but rapidly, we decided to deploy it on site, in order to demonstrate its technical viability. We present the technology Batiprint3DTM and the demonstrator YhnovaTM, a 95m2 social dwelling built for the social landlord Nantes Métropole Habitat (NMH).

Supermacroporous three-dimensional matrices based on poly-D,L-lactide or polycaprolactone were fabricated by thermally induced phase separation method and 3D printing technique. The morphology and mechanical properties of the resulting matrices were studied with the use of optical and scanning electron microscopy and the uniaxial compression test, respectively. All matrices were characterized with supermacroporous structure suitable for cell penetration. A significant increase in Young's modulus and tensile strength was established for both polymer matrices prepared by 3D printing technique.
