3D Printing technology allows the production of an individualized 3D object based on a material of choice, a specific computer- aided design and precise manufacturing.3D Printing technology has a wide range of applications in dentistry. Therefore, the present study aimed to evaluate the knowledge and practices of dentists in Uttarakhand regarding the use of 3D printing in their usual practice. Material and Methods: The study was conducted in the form of a self-administered online questionnaire consisting of 19 questions which were circulated among the dentists by generating a google link for the survey and sending it to the willing participants via various social media platforms and e-mails. Statistical analysis was carried out using SPSS version 17 software and Chi square test was applied. Results: 83.1% of the participants were aware about the use of 3D printing in dentistry, 68.5% had an idea about it’s non- dentistry related uses and 43.8% knew its working principle. 54.2% respondents were unaware about the best material for 3D printing. Only 33.5% were aware of all of its procedural expenses. Just 20.8% had an experience of either observing or working with 3D printers of which 33.8% thought that it had enhanced their ability to execute the surgical procedure. 79.2% had no experience of using 3D printers, the reason mostly being unavailability in their area of practice. A statistical difference was found in the knowledge and practices based on age, sex, education, and experience with P value <= 0.05. Conclusion: Precise knowledge of 3D printing is necessary for enhanced predilection and treatment outcomes. Based on the outcome of the study dentists should be encouraged with optimal hands-on training to ensure its unhesitating and efficient practice
