N2 - 3D printers allow for the rapid construction of complex 3D objects that would be very time-consuming with traditional casting techniques. Patient-specific objects have been created for years in the fields of dentistry, prosthetics, and surgical guides. However, 3D printed objects using materials that also serve a functional purpose, biologically or chemically, are now finding bio-medical applications. A custom 3D printer has been made that is able to print the FlexyDos3D silicone dosimeter, but the dosimeter’s sensitivity is severely decreased after printing. Testing was performed to determine if chloroform is lost during printing and techniques were tested to reintroduce chloroform into the dosimeter after printing to improve the dose response of the dosimeter. Results showed that the chloroform was completely evaporated from the dosimeter when exposed to conditions similar to that during printing and that chloroform could be reintroduced by soaking or exposure to chloroform vapours which led to an increase in the dose sensitivity. Further testing of the reintroduction of chloroform into the dosimeter is ongoing.
