3D printing is everywhere, impacting industries such as healthcare, aerospace, manufacturing and practically any other area you can think of. However, in the big picture, adoption of the technology is still relatively low. Why is that? In a paper entitled “Understanding the determinants of novel technology adoption among teachers: the case of 3D printing,” a team of researchers argues that one big hurdle to adoption of 3D printing is the lack of sufficient technology education. The paper investigates the behavioral intention of high school teachers to use technologies such as 3D printing in class.
“At the global scale, numerous universities (e.g. MIT) have already integrated 3D printing classes in their curricula,” the researchers state. “In Austria, some universities (e.g. AAU Klagenfurt, TU Graz) run 3D printing labs. Comprehensive 3D printing education at the high school level is crucial to enable the timely development of required skillsets, yet 3D printing is still novel at the high school level.”
In the study, the researchers used the previously developed Unified Theory of Acceptance and Use of Technology (UTAUT) model of investigation as a basic to develop their own research model. UTAUT proposes three direct predictors: performance expectancy, effort expectancy, and social influence of an individual’s behavioral intention to use technology. The researchers set up a project called “SmartLab Goes to School,” in which high school were invited to present innovative ideas for using 3D printing technology for the chance to win a 3D printer for classroom use.
A questionnaire was distributed among Austrian teachers, resulting in a sample size of 103 respondents. 84 teachers stated that they had experienced 3D printing technology, while 19 replied that they had no experience with it. Unsurprisingly, teachers who taught technical subjects were found to have stronger inclinations to teach 3D printing technology than teachers of more academic or business education subjects. Interestingly, teachers with no 3D printing experience had stronger inclinations to use 3D printing, suggesting that many teachers who have used the technology have had negative experiences with it in the past.
Several of the researchers’ hypotheses were supported, including:
- Teachers with high levels of performance expectancy are more likely to have a stronger intention to use 3D printing technology
- Teachers with high levels of anxiety are less likely to have a stronger intention to use 3D printing technology
- Teachers with a positive attitude towards using 3D printing technology are more likely to have a stronger intention to use 3D printing technology
- Teachers who perceive facilitating conditions positively are more likely to have a stronger intention to use 3D printing technology
“The main goal to contribute to a better understanding of teacher acceptance of novel technology and their intention to use it was thus achieved,” the researchers state. “The findings provide evidence that there is a strong intention among teachers to use novel technology. Further, we demonstrate which personal and environment-related factors affect novel technology adoption.”

Anxiety was a significant factor in the hesitancy of some teachers to use 3D printing – anxiety about making uncorrectable mistakes, for example, or apprehension about technology in general. Teachers were positively influenced toward using the technology by knowledge about its benefits, as well as the feeling that they had the proper resources, knowledge and support. Thus, the researchers conclude that the introduction of technology into classrooms is not just a financial or technical issue, but depends on the level of support teachers are provided.
Authors of the paper include Patrick Holzmann, Erich J. Schwarz, and David B. Audretsch.
