This research attempts to examine the role of 3D printer as a learning tool in inclusive education. It examines the quality of verbal and nonverbal interactions between students with disabilities (SWD) and students without disabilities (SWOD) in an inclusive classroom at primary schools, where 3D printers were used as a learning tool. The results presented in this paper are based on qualitative and quantitative analysis of interactions between 7 SWD and 31 SWOD. Even though both occurred, there was no statistical difference in generation of positive and negative verbal and nonverbal interactions between SWD and SWOD. Both, SWD and SWOD are of the opinion that cooperative learning with implementation of 3D printers contributes to their communication with peers, achieving better and durable knowledge in the subject where this learning approach was applied and they would like to learn in this way in the future.
