3D printers are a modern technology which is new to most students and can be used to motivate them. However, if the use of a 3D printer is limited to the downloading and printing of prefabricated models, the students will learn little about computer science. In this article, we present an approach for learning basic programming skills, which is based on the programming of three-dimensional objects using turtle graphics in Beetle Blocks. In addition, there should be an interdisciplinary link to the functions taught in mathematics teaching. The motivation was the creation of a 3D figure based on mathematical functions, its creative elaboration and its 3D printing at the end of the sequence. The experience shows that students are inspired by the idea, but the link with mathematical foundations is a challenge.
