“…The obtained 3D digital data provide a convenient data set, which can be used to quantitatively analyze and calculate the characteristic indices for the natural joint, such as the roughness, magnitude and angularity. [4] From the point of view of the material, any matte surfaces are suitable. In the case of shiny surface, it can be treated with a chalk spray for the purpose of scanning, which can be easily washed after completion of the work.…”

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.

“…In the context of these aesthetics and principles, and of ideas of permanence, we would argue that a key factor today is that advancing recording technologies offer the potential to ostensibly obviate the conjectural aspect of the documentation process. Digital reality capture (especially laser scanning and photogrammetry) has never been associated with greater levels of point cloud density and completeness of data and therefore would logically support re-creation based on the concept of 'digital pattern books' or in current parlance, scan to HBIM and Scan to 3D print applications (Jiang et al, 2016). This has become more contentious given recent advances in 3D printing technologies that potentially, materially and textually facilitate the recreation of components that, when cumulatively combined, may recreate holistic schemes (Guardian, 2016).…”

In this conceptual paper, we illuminate Western building conservation philosophy practice with insights into Eastern conservation philosophy and associated aesthetic understanding. We frame dialogue recognising individual and societal perspectives on treatments to buildings that attempt to attain 'permanence' or 'impermanence' in form, fabric, and artefact. Although not expressly sharing origins, Eastern and Western conservation philosophies practically yield commensurate or quasi approaches in intervention. These similarities have not been notably articulated before, and reveal meaningful insights for decision heuristics and guidance fundamental for repair scheme design and intervention. Western, pattern-based views relating to philosophical reasons around the impossibility of perfection, or 'correctness' in physical building form resonate with Eastern views supported by Kiku Kiwari. Moreover, universality in acceptance of Western Patina and Eastern Wabi-Sabi, and Eastern Kintsugi and Western legible fabric repair convey overt signals of philosophies beyond technical performance. Moreover, we find Western bias towards 'tangibility', and greater appreciation of 'intangibility' in Eastern approaches that are culturally enriching and go beyond mere retention of fabric and architectural form, linking building memory with territory. We suggest potential cross-fertilisation of thinking to create an environment of greater cultural understanding of the motives, thoughts and practices in East and West.

“…The demand for using the technology has increased from single manufacturing events into a complete AM process starting from CAD designing into the post-processing. 3D scanning is seen as an important part of the AM process since it offers the possibility of reengineering parts in many areas (PLM Group, 2019;Jiang et al, 2016 andPaulic et al, 2014). For this reason, the model for AM process selection presented in this study contains 3D scanning as a substrate for 3D model.…”

Additive manufacturing (AM) is at the verge of being recognised as one of the main manufacturing methods among the traditional ones. The largest obstacle in using AM in the companies is the lack of knowledge about the possibilities of the technology. One sub-problem caused by this is the lack of qualified machine operators in companies due to the insufficient AM education. This indicates the need for strengthen the current AM education especially in the B.Sc. and M.Sc. levels in engineering education by emphasising the importance of AM in curriculum development. This study presents novel learning outcomes based on the needs of manufacturing industry and companies in Finland. A questionnaire was conducted to work-life representatives in order to map the requirements for AM education in the mechanical engineering degree of the Lapland University of Applied Sciences in Finland. The responds were collected as competences representing different areas of AM knowledge and the learning outcomes were derived from the responds. AM education must also provide a model for selecting the most suitable AM technology in order for students to learn the technological aspects. This study also presents a process selection model which can be used in AM education. The model allows the student to compare different AM technologies from different perspectives such as material, functionality and visual appearance point-of-view.
