Development of catalyzable resins, silicones and hydrogel using UV to be processed by additive manufacturing

Abstract

This report is the continuation of a project whose aim is to develop an organ by 3D printing which mimics perfectly human organ. A prototype has already been established but it is expensive, so the purpose now is to reduce the cost of this technology. In this report, different materials (silicone, hydrogels…) have been tested in order to know if they suit with 3D printing technology. 3D printing is a new technology used in order to manufacture products with complex geometry. That is why, 3D printing can be interesting for this biomedical application because organs are complex and unique to everyone. In this project, different techniques have been used. Materials like phytagel have been printed with different parameters (change of syringe, different area of printing…). Moreover, those materials have been casted in mould printed by a FFF 3D printer. The results are not indisputable because some mistakes may have been made by the operator (placement of the syringe, quantity of air bubbles in the syringe…) and all the conditions were not at every time the same.
