    Opis:
    The availability of 3D scanning devices allows performing the process of digitisation of a growing number of diverse museum artefacts. After the properly conducted processing of the acquired point cloud, the authors obtained a photorealistic digital copy that can be presented in many ways. With regard to the objects from archaeological excavations, the vast majority are the artefacts that are more or less damaged or only partially preserved. Their state of preservation, specialised archaeological knowledge and the use of appropriate 3D computer technologies allow their complete digital reconstruction. The present work concerns the development of alternative methods and algorithms of conduct, the selection of programs and tools to recreate the surface of the outer and inner side and the bottom of a 12th century pitcher from the Afrasiab excavations in Uzbekistan.

    Opis:
    Counteracting the social and educational exclusion of visually impaired people is an important issue in the area of knowledge transfer, also in the area of cultural heritage. Visually impaired people get to know the world in an organoleptic way, where the leading cognitive factor is touch. This type of cognitive method cannot be used in museology and historical architecture. Current attempts to solve this problem lead to the use of additive technology understood as 3D printing. The paper presents a modified procedure for obtaining digital 3D models with the use of Autodesk Inventor version 2021, dedicated to creating scalable replicas of architectural objects using additive technology. The applied procedure uses the decomposition of the object into its components and the acquisition of data from terrestrial 3D laser scanning (FARO Focus 3D scanner, Faro Scene software). Printing in the Fused Filament Fabrication technology of a designed minaret representing the architecture of the Timuridian period (minaret of the Ulugh Beg Madrasa in Samarkand, Uzbekistan), originating from the Silk Road area, was carried out due to the size of the facility, divided into several parts. The obtained replica of the minaret was presented to people with simulated pattern dysfunction and tested in a pilot test. The obtained results confirmed that the decomposition of the object for the purposes of 3D modelling, the diversified scaling of individual elements to make real 3D replicas of the digital model facilitated the kinesthetic recognition of the relevant architectural object for the respondents.

    Opis:
    This paper evaluates the wear characteristics of hardfacing coatings. Regenerative hardfacing coatings were applied with the TIG (Tungsten Inert Gas) method. The solid welding wires were used to obtain the coatings marked as: EL-500 HB, EL-650 HB, and EL-3348. The tribological analysis of samples was conducted at room temperature. The wear rate was evaluated with a THT 1000 Anton Parr ball-on-disc tribotester, in accordance with the ASTM G-133 standard. The counterbody (static partner) consisted of balls with the diameter of 6 mm made of Al2O3. The test was performed with the sliding speed of the friction pair 0.4 m/s, track radius 10 mm, normal load 20 N, acquisition rate 10 Hz and sliding distance 2000 m. During the test, the friction coefficient and wear rate were recorded. The multi-criteria assessment of the construction materials discussed, while taking into account five criteria, showed that EL-3348 HB is the best material. Computer applications were used for multi-criteria assessment and statistical processing of data.

    Opis:
    3D printing of historic architectural objects reduces the entire digital model by up to 200 times. With this scaling of the digital 3D model, many important architectural and decorative details are lost, and some elements lose their stiffness. Printed 3D models are now used to create specialised museum exhibitions that allow visitors to get to know them kinesthetically. This ability to touch objects applies not only to visually impaired people, but to all interested visitors. The paper describes the preparation of a digital 3D model (D3DM) dedicated to 3D printing by decomposing the real model into sub-models and using different scaling values for individual elements. The practical part presents three-dimensional modelling of historic architectural objects of Lublin and their replicas made on 3D printers in the Fused Filament Fabrication (FFF) technology. Virtual models designed in this way retain important details of objects and are also scalable as a whole, which allows for obtaining printed objects of various dimensions.

    Opis:
    This paper investigates properties of single- and double-layer pad coatings deposited on cultivator points. The coatings were deposited by manual metal arc welding (MMA) with ESAB OK. 84.58 coated electrodes using an inverter welder, DEDRA DESi201. Tribological properties were determined with a THT 1000 tribometer. A ball-on-disc friction pair was used. Experiments were performed in room temperature, with the sliding speed set equal to 0.3 m/s and two loads: 5 and 20 N. In addition, hardness was measured on the surface and in the cross section of samples by a Rockwell hardness test method (scale C). Surface roughness was measured before and after friction, and post-friction surface topography was examined under microscope. Impact strength tests of the coatings with single- and double layers of pads were performed. The tools and IT algorithms were used to collect and process the results of experimental research.

    Opis:
    The paper presents a process of testing a created virtual reality application for displaying the "Hujra", a room for students of the 17th century madrassa in the area of the Silk Road, together with interactive objects. The designed 3D objects had sufficiently small file sizes to be introduced into virtual reality, and the fully mobile application worked effectively using smartphones within the price group available to the average user. The application was presented to a group of students and researchers from Kyrgyzstan. In addition, objects not belonging to the Islamic culture were introduced into the students' room. Pilot tests confirmed the usefulness of the proposed solution of 3D modelling. Interviews with the participants of the experiment and the results of a survey showed that the virtual reality application was a very attractive form of presentation, especially for people belonging to Generation Z. The combination of the complexity of the project and its high availability via smartphones was considered a successful solution by those questioned.
