Due to the effects of climate change and the depletion of natural resources, the need to move from a linear to a circular economy is clearer than ever. Composite technology will play an important role in this. In recent years, the consortium has devoted itself to an intensive valorisation project, in which the focus was on developing basic 3D printing techniques and thermoplastic raw materials preparing for printing on XXL scale. Important bottlenecks still stand in the way of scaling up. The main objective of this project is to scale up 3DXXL printing technology and close the chain to exploit the full potential of 3D XXL.
