The PEPS project sets out to develop macromolecules realised by 3D printing in order to meet the needs of companies in an appropriate and creative way. The aim is to develop the cross-border potential of additive manufacturing processes for technical polymers, to broaden the possibilities of additive manufacturing processes and to steer them towards new industrial applications. This comprehensive cross-border approach is made possible by bringing together the complementary skills and expertise of PEPS partners in many areas. Synergies are therefore expected between partners at each level of action of the project.
