Advanced Tinkercad Workshop on Boolean Operations – Medelova SS, Erasmus+ 3D Academy
On the second day of the P1 – “3D Printing Step by Step” mobility in February 2026 at Medelova Secondary School in Novi Jičín, Czech Republic, students participating in the Erasmus+ 3D Academy project attended an advanced Tinkercad workshop focused on Boolean operations and object combinations.
The workshop built upon the introductory session from the previous day, guiding students through more sophisticated modeling techniques. In particular, the instructors focused on union, subtraction, and intersection operations, which allow designers to combine multiple primitive shapes into complex models or remove parts from objects to create intricate geometries.
Students learned how to create models with “holes” or cutouts, merge multiple shapes into a single object, and manipulate the relative positions of components to achieve the desired final form. The workshop emphasized the importance of understanding object relationships and geometry to ensure that the resulting models are suitable for 3D printing.
Another key topic was the preparation of models for 3D printing. Instructors demonstrated how to export completed designs from Tinkercad in standard formats such as STL or OBJ, and how to verify that models are watertight and free of errors to avoid printing issues. Students were shown the basic principles of digital curing or slicing, where the 3D model is processed to generate the layers and instructions required by 3D printers.
The workshop also provided practical examples of how Boolean operations simplify complex designs, making it possible to create functional parts, decorative elements, or prototypes with precise geometries. Students practiced exporting their models and preparing them for resin or filament-based 3D printing, reinforcing the connection between digital design and physical production.
This advanced session allowed participants to refine their 3D modeling skills and understand the workflow from conceptual design in Tinkercad to a ready-to-print 3D object. By combining creative exploration with technical preparation, students gained confidence in producing models suitable for both educational and professional applications.
For the Erasmus+ 3D Academy students, this workshop was a crucial step in mastering additive manufacturing processes. It complemented earlier experiences with filament, resin, and powder printing, as well as 3D scanning, giving them a comprehensive understanding of the entire 3D printing workflow.
The activity was an integral part of the mobility P1 – “3D Printing Step by Step”, reinforcing the project’s goals of developing practical digital skills, encouraging innovation, and fostering hands-on international learning experiences.
