3D-printing has begun a revolution in complex shaping. It translates virtual 3D models into physical objects in a controlled process of joining materials, usually layer-by-layer, for instance, using polymers, metals or ceramics. Due to its versatility, 3D printing is an affordable technique (easy prototyping, print on demand, cheap, etc.), which will lead to an increase of home-made disposable products, creating throwaway items, as the 3D printer usage is expected to grow rapidly.
Thanks to their broad range of properties, petroleum-derived polymers are the most common group of materials used in 3D photopolymer printing. However, their persistence has caused a worldwide waste managing problem. Moreover, the crude oil is a finite resource. These remain a visible barrier in a greener development of 3D printing and must be overcome.
Indicating direction-dependent properties i.e., gradient, in 3D printed photopolymer is a new possibility to realize their specific functions. These includes structural (variation of the filler size, distribution; variation of the porosity in foams, etc.) and chemical (variation of concentration, phase separation, etc.) gradients, or combination of both.
In this project, you will synergistically combine the ideas for gradient 3D printing with bio-based or/and bio-degradable polymers. The methods for gradient 3D printing will be developed. Biopolymers will be derived from plants and chemically modified. Biodegradation will be studied. You will aim at engineering and scientific approaches: to propose new printing solutions and sustainable materials but also to understand the processes and phenomena occurring at “boundaries” of such inhomogeneous final materials. The outcome of this project should provide new knowledge that will enable the design of 3D printing materials to be more environmentally friendly while maintaining gradient functionality.Your profile
