The partners of the PEPS project are also developing new, more ecological materials for 3d printing. These filaments represent an alternative that can have a reduced cost, more respectful of the environment. 3D printing requires a large amount of energy and frequently uses petroleum-based materials such as ABS for example, one of the most widely used materials when it is used to 3D printing by molten filament deposition.
These recent developments, within the framework of Interreg projects (Composens and Doudou) offer the possibility of 3D printing in a more ecological and eco-responsible way. These natural filaments or made from recycled materials have been developed to respect environmental constraints and offer alternatives to petro-based filaments. By incorporating in a polymer base, which can be biosourced like PLA, recycled or biosourced materials in the form of fiber or powder, it is possible to create filaments including a certain percentage of renewable or biosourced material.
