AMC at the 100th Anniversary of the Deutsches Museum – Inspiring the Next Generation with 3D Printing
We were honored to take part in the 100th anniversary celebration of the Deutsches Museum in Munich with a hands-on workshop designed to introduce children and families to the fascinating potential of 3D printing in construction. Together with Anna Keune and Ziva Simsic from Project Ö, we hosted a workshop that bridged the digital and physical worlds. Participants first explored digital design by creating their own structures using Tinkercad in the TUMlab at the Deutsches Museum. They then brought their ideas to life using clay—translating digital creativity into tangible forms. The response exceeded all our expectations: over 300 people took part in the workshops at TUMlab, and the enthusiasm was overwhelming! A heartfelt thank you to the Deutsches Museum for …
