3D Printing on Saturday at the Interim of the Central Library: Creative Technology for Participation

On Saturday, September 19, 2026, the Interim of the Central Library in Cologne will open its workshop for anyone who wants to bring their own 3D files to life. This free format combines digital design, practical application, and a direct art experience between the library, makerspace, and technical curiosity.

When File Becomes Form

The appeal of this event lies in the transformation: A digital design turns into a tangible object. Those who bring a 3D file in .stl format on a USB stick will experience how data gradually grows into a small work. This is precisely where the unique exhibition atmosphere of this format lies: not observation from a distance, but active viewing of the work in progress.

An Open Offer for the Curious and Practitioners

The City Library of Cologne provides the offer without prior registration. No prior knowledge or membership is required. Printing will be done in the order of arrival, as long as time permits. This makes the event an accessible entry point into the world of 3D printing, effectively bringing together digital design, materiality, and cultural education.
