Yesterday Dubrovnik shone once again as a centre of curiosity and technology! At the third DU STEM Festival, part of the 10th Robo.Du Days, we presented the possibilities of digital fabrication and 3D printing, new materials and interactive STE(A)M activities. Our educational exhibits and hands-on sessions from the project „STEM as a driver of development“ drew many visitors of all ages, who experienced first-hand how technology and creativity come together in practice. The festival brought together many associations and other organisations, and the atmosphere was fantastic – full of curious questions, discoveries and smiles.
