## 1 Introduction  
In recent years, the rapid developments of digitization have reached cultural heritage. Technologies such as digital archiving, documentation, and reconstruction, 360\({}^{\circ}\) capturing, 3D laser scanning, modelling, and printing are influencing the way cultural heritage is maintained, managed, and preserved, as well as the way it is observed by visitors and audiences in general. In addition to the technologies, augmented, mixed, and virtual reality are also increasingly being used in the cultural heritage sector [1]. These new technologies can help increase the reach of cultural heritage. In some cases, they can extend and expand the life of cultural heritage when its original physical manifestation is no longer present [1]. Technologies are now financially affordable, and quality is increasing. The decline in price [2] and the increasing accuracy of 3D printing technologies [3] are now providing new ways to represent and analyse cultural heritage. This \"digital cultural heritage\", also referred to as \"heritage information resource\" [4], can extend the life of heritage and become accessible to everyone. A cultural heritage is defined by its historical relevance and artistic qualities, but also by its cultural values, identity, associations, and ability to evoke memories [5]. If we focus on 3D printing of sculptures, this opens new possibilities in the field of research and accessibility of this cultural heritage. One of the most important and probably most obvious advantages of 3D printing is its high flexibility compared to traditional methods of producing copies of sculptures. Three-dimensional-printed prototypes can be touched without fear of damaging them. Thus, they represent a new way of interacting with exhibits. There are many factors to consider if we would like to get as close as possible to the original. For example, we also need to consider texture, weight, and final appearance, which is sometimes difficult to achieve with 3D printing [6; 7] and \"material poetics\" may be lost [8]. Three-dimensional capturing technologies and processing methods differ in terms of accuracy and thus the final results of 3D printing. When we capture with different technologies, we obtain a point cloud that depends on the accuracy of the capture. During processing, different filters are used to optimize the digital model, which in turn can affect the geometry of the model. Metrics obtained by photogrammetry or laser scanning often contain a lot of noise [3; 6]. We can also create 3D prototypes of the exhibits using the 3D modelling process, but we must be aware that such models are ultimately only an approximation of the original, as they are the result of interpretation [6]. Each artwork requires a unique approach, especially in the capture of the artwork's digital data and data processing. Depending on the characteristics of the artwork, such as size, construction, material, age, and condition, we determine the conditions for capturing, equipment and further data processing. For the capture of wooden sculptures, both photogrammetry and scanning prove to be reliable capture methodologies. Each method has its advantages and disadvantages, and the choice of method depends on the sculpture in question [9]. When feasible, computed tomography (CT) could be a valuable examination technique for 3D visualization and analysis of the internal structure of wooden sculptures (life size), their construction with various joint materials (nails, dowels of different wood type) or internal damages (cracks, woodworm tunnels) [10]. New technologies are becoming increasingly important in the field of conservation for digital records of artworks for research, documentation, reproduction, and treatment purposes. In certain cases, they can help to reassemble (broken) sculptures [11], or they can be used for the preparation, virtual sculpting, and printing of missing elements of artworks [12]. Three-dimensional data of artworks also help in the production of storage and transport packaging for museum collections [13].
