Abstract Sustainability and an ecological future of construction can be secured by new materials, but also by different and modern views on the basic principles of the construction industry. Modern technologies must also enter the construction space, robotics, artificial intelligence, and other approaches must not be neglected. One of these is 3D printing, which is finding its way into many industries and is also already part of our everyday lives. In general, 3D printing of composite concrete materials is well known, but that's not the only way the construction industry can take. The brief literature review presented here dealing with the applicability of 3D printing in the construction industry with a focus on plastics and metals. Furthermore, it presents the basic principle of the applicability of 3D printing for the development and application of a joint applicable, for example, for the connection of a membrane structure to a load-bearing element. Concise considerations and recommendations for further applicability of 3D printing in plastics and metals are presented. © 2024 The Authors. Published by Elsevier B.V.

1. Introduction In recent years and decades, the construction industry has been faced with new challenges and tasks that need to be solved with new technologies and approaches. One such approach is 3D printing (Su and Al’Aref, 2018). It all starts with a 3D model, thanks to which the printing equipment gradually transforms the shape into the final form. It can use materials such as concrete, metal or polymers to create a 3D structure (Cuevas et al., 2021; Juracka et al., 2022).
