The aim of the paper is to bring new findings from ongoing specific university research. Within this project, the light scanner scanned historically and culturally significant objects referring to the work of Czech-Austrian writer Adalbert Stifter in South Bohemia and Lower Austria. It also analyzed the data obtained with the light 3D scanner. The data was generated as a cloud of points. With respect to object´s size, multiple parts of each object were scanned individually. By combining individual scans and removing unwanted points (noise), models - digital twins of objects - were developed. Created models are valuable for their use for virtual tours of historically and culturally significant places. The final models were modified for printing on a 3D printer, where they were subsequently printed.

The aim of the paper is to describe the methodology of creating a digital model of human using an optical 3D scanner. This methodology consists of several main phases, such as preparing the scan for human movement, scanning in the shortest possible time, and processing the data obtained by scanning. The data processing itself is divided into other sub-phases, which describe the individual steps necessary to create a digital model. The paper describes obstacles that need to be eliminated or minimized during 3D scanning in order not to disrupt the integrity of the model and to create a digital model.

Nowadays, we use many of the modern technologies to make the optimal design of new buildings. Building Information Modeling Technology offers state-of-the-art solutions that allow the design of a building to create in many variants a realistically time-consuming development process and, by virtue of an almost fully automatic assessment of the variants, choose the most appropriate one according to the required criteria. Such a design of the building assumes its optimal behavior according to the criteria required by the investor, the user and other stakeholders, but also helps to keep the construction towards the sustainable development goals. There are many existing buildings that have obsolete properties. The management and durability of such buildings is very costly. Such buildings should be refurbished to meet the properties and imitations of new building behavior. 3D scanning technology goes hand in hand with the building sector digitization and outputs from 3D scanning technology serves as a useful basis for further working with data using BIM technology. This paper outlines the possibilities of creation of basics for current documentation with graphical information of these buildings and how it may serve for evaluation of possible options for repairs and reconstructions through the whole building lifecycle and further use in facility management.

The paper describes the practical use of modeling processes and 3D printing for the production of furniture, decorative and other objects. Using 3D modeling and printing on a 3D printer, it is possible to create a mold and subsequent product with a much more complex shape than would be possible with hand-made formwork or mold, or at least much simpler. Demonstration of applicability of these molds was carried out by an experimental method when the molds were poured out by cement or concrete from the fine aggregate. The forms themselves were formed from PLA filament. Experiments have shown the usability of such molds for complex concrete elements. These forms can be reused. Damage to the molds occurred during handling or cleaning, i.e. rough handling. During the filling itself and the process of cement hydration, they were not damaged. For a longer mold life, it is necessary to print in a larger percentage of filling, which, however, makes the mold more expensive. The durability of molds and better formwork is obtained by using formwork oil.
