Abstract:

The bachelor thesis deals with additive manufacturing in the construction industry and with materials used in this field. The first part of the thesis defines the 3D printing, briefly describes the history of this progressive technology and gives an overview of the used methods and technologies. The printing methods are divided according to the physical state of the basic material used for printing. The next part of the thesis presents the possible use of additive manufacturing in the construction industry and an overview of realized projects. Finally, at the end of the theoretical part are introduced materials applicable to additive manufacturing in the construction industry and is defined the concept of spatial materials. Spatial materials are a relatively new term, which is not yet in the literature sufficiently defined. These materials can be used for an application in a space where the structure and the position of their particles can be optimized. They can be applied for the creation of 2D filling structures, which are more useful for geometrically simple and simply loaded constructions. It is preferable to use spatial materials to create 3D structures that are designed to fill numerically optimized structures. These structures are based on the principle of double curvature and on a triply-periodic minimum surface (TPMS). In the practical part of the thesis was created the design of building block filled with 3D gyroid structure, designed for prefabrication by using additive manufacturing in the factory or at the site of construction. This proposal reflects the increasing demand for easy individualization of constructions and building elements. Especially, the demand for the creation of structures and shapes which are topologically optimized with a customized appearance and sufficient strength, all at the customer's request.
