Fabrication technology polymerization methods

Three-dimensional printing can be used to create resorbable devices with complex concentration profiles within the device (65). This method belongs to solid freeform fabrication methods. Both macrostructure and microstructure can be controlled. The application of this technology for the fabrication of polymeric drug delivery systems has been elucidated. 

This review will highlight the interrelationships between basic photopolymer science and practical applications of this technology. Each application of photopolymer technology can be described in terms of three primary descriptors the mode of exposure, the mechanism of the photopolymer reaction employed and the visualization method used. Using this foundation, the widely diverse applications of photopolymer technology to electronic materials, printing materials, optical and electro-optical materials, the fabrication of devices and polymeric materials, adhesives and coating materials will be discussed.
