Three-dimensional scanning technology is expected to continue to grow and advance in the future, with many exciting possibilities on the horizon. One of the main areas of growth is expected to be in the field of augmented and virtual reality, where 3D scanning will play a critical role in capturing real-world objects and environments for use in immersive experiences. Additionally, there is growing interest in using 3D scanning for monitoring and tracking objects and people in real-time, which can have applications in fields such as logistics, security, and sports. With the advent of more advanced sensors and algorithms, it is also likely that 3D scanning will become more accessible and affordable, making it possible for a wider range of individuals and organizations to use. Overall, the future of 3D scanning technology is bright, with many exciting opportunities to enhance the way we interact with the physical world and gather information about it. As the technology continues to evolve, it will likely have a profound impact on the way we live and work. Likewise, 3D printing technology is expected to have a major impact on various industries in the future. In manufacturing, it is predicted to play a larger role in mass production of complex and customized products. In healthcare, 3D printing is expected to play a bigger role in producing custom prosthetics, implants, and surgical models, and it is also likely to contribute to the advancement of personalized medicine and tissue engineering. The construction industry is also expected to be impacted by 3D printing technology, as it has the potential to revolutionize building construction processes by allowing the printing of entire buildings and houses, leading to faster and more efficient construction methods. Moreover, 3D printing has the ability to reduce waste and contribute to a more sustainable future by producing only what is needed, when it is needed [103; 104; 105; 106; 107; 108; 109; 110]. Consumer goods production is also expected to change as a result of 3D printing, which can enable the production of items at home, tailored to specific needs and preferences, and on demand. Three-dimensional printing technology has advanced significantly over the years and is constantly evolving. The next frontier in 3D printing is 4D and 5D printing. Four-dimensional printing refers to the addition of a time dimension to 3D printing, allowing for the creation of objects that change over time. For example, 4D-printed materials can respond to environmental factors such as heat, light, or moisture, and change their shape or properties accordingly. Five-dimensional printing, on the other hand, involves the integration of multiple functionalities into 3D-printed objects, such as sensors, electronics, and other materials. This opens new possibilities for creating smart and interactive products with unique capabilities, from wearable devices to self-assembling structures. As 4D and 5D printing continue to evolve, they have the potential to revolutionize the way products are designed and manufactured, leading to new and innovative solutions to a wide range of challenges [111; 112]. In the field of cultural heritage, both 3D printing and 3D scanning are poised to play a critical role in preserving and studying the past. With 3D scanning, it is possible to create highly accurate digital representations of artifacts and cultural sites, which can be used for research, preservation, and educational purposes. Three-dimensional scanning can also be used to monitor the condition of objects over time, helping to identify and address potential problems before they become more serious. Additionally, 3D scanning can be used to create virtual exhibits and educational resources, making it possible for people around the world to learn about cultural heritage without having to travel. Three-dimensional printing, on the other hand, has the potential to create highly detailed replicas of cultural artifacts and sites.
