The BUTTERFLIES project addresses the growing need for sustainable and digital transformation in advanced manufacturing.
It targets the widespread adoption of biopolymers in additive manufacturing (AM), using chitin and chitosan, natural, biodegradable materials,
to reduce dependency on fossil-based inputs.
By leveraging these materials within Binder Jetting (BJT) and Two-Photon Polymerisation (2PP)
technologies, the project promotes greener production methods. This responds to the broader European objectives under the twin transition
framework: the green and digital transformation of industry.
The project aims to develop and validate advanced AM processes using chitin and chitosan to create high-performance, sustainable, and biocompatible
products, particularly for biomedical use. Specific objectives include optimising chitin nanocrystal (ChNC) binders for BJT, developing
photo-curable chitosan bio-polymers for 2PP, designing novel AM equipment, and integrating AI/ML tools to optimise processes.
These efforts align with EU targets for circularity, reduced environmental impact, and enhanced competitiveness in manufacturing.
