| Abstract Scope |
The "polymer" 3D printing was invented in the 1980s, we see that today, there is a very limited choice of resins or polymers compatible with this process, greatly limiting the range of final properties or functionality of the 3D objects obtained. Hence, this project deals with the implementation of 3D printing processes to manufacture complex three-dimensional objects that are able to react to their environment, process so called 4D printing. To achieve this goal, new resins for additive manufacture by photopolymerization are developped. In order to obtain a 4D effect, colloidal metallic nanoparticles with different shapes have been synthesized and then introduced into the photosensitive resins. Different objects of controlled geometry have then been realized by photopolymerization according to the desired effects. Several stimuli (light, temperature, stress mechanical) have been explored. For example, on a macroscopic scale, one can imagine producing a colour change induced by light (photochromic) or mechanical stress (mechanochromic). At the microscopic scale, the aim will be to propose miniaturized actuators controllable by light or temperature. These programmable materials will be able to find application in several fields such as sensors, robotics or the microfluidics. |
