Three-dimensional (3D) printers, can essentially be defined as tools that allow individuals to take physical outputs of objects as 3D that they previously designed through computer-aided support programs. In this context, it is aimed to determine teachers' views on the instructional use of 3D printers within the scope of the present research. In current research case study method was used as one of the qualitative research methods. In the scope of this study, 10 males and 19 females, totally 29 participants, who were teacher at a middle school, were included into this research. It was observed that the new 3D printers, which were introduced in learning environments, were appreciated by the teachers who will implement this technology and the teachers were influenced by the existing technology. It can be said that the use of 3D printers for teaching purposes is extremely beneficial. In the field of education, especially in the basic fields of Science and Mathematics, 3D printers are thought to have a significant impact.
