In cultural heritage study of 3D modeling has become a very useful process to obtain indispensable data for documentation and visualization. 3D scanning and 3D printing suggest a vital solution in preserving and sustaining traditional folk costumes. 3D scanning and 3D digitizing is defined as the process of using metrological methods to ascertain the size and shape of a scanned object, which may often involve an optical device that rotates around the desired scanned model. In digital preservation, especially for three dimensional physical artifacts in various crafts, the geometric shape of an object is most important. The aim of this paper is to show 3D scanning technology that produces a high-precision digital reference document to provide virtual model for replication, and makes possible easy mass distribution of digital data. We also experimented with 3d Additive manufacturing or 3D printing to show a way to actualize digital forms of folk accessories for the experimental manufacturing and to show a way how to preserve nowadays the original object. The work includes scanning, modeling, and printing of waist coat and of coin handicrafts. Experiments will be carried out on 3d scanning, 3d modeling software, reconstruction and fabrication -rapid prototyping.

This chapter outlines the advantages of digital epigraphy in the context of the original monuments. It analyzes the perception of epigraphic publication of monuments, taking into account new technologies. 3DVR models can be created using architectural drawings and measurements (CAD and 3D modeling), 3D scanning, and Structure for Motion (SfM). These systems present different advantages and challenges, which are discussed. Current options for publication include VSim, 3D GIS, and Unity 3D platforms. The issues of peer review of publications and long-term preservation of data are addressed. The chapter concludes with a consideration of the issue of potentially misleading impressions given by 3DVR representations.

Mesh Work

Although three-dimensional (3D)-printed anatomic models are not new to medicine, the high costs and lengthy production times entailed have limited their application. Our goal was developing a new and less costly 3D modeling method to depict organ-tumor relations at faster printing speeds. We have devised a method of 3D modeling using tomographic images. Coordinates are extracted at a specified interval, connecting them to create mesh-work replicas. Adjacent constructs are depicted by density variations, showing anatomic targets (i.e., tumors) in contrasting colors. An array of organ solid-tumor models was printed via a Fused Deposition Modeling 3D printer at significantly less cost ($0.05/cm3) and time expenditure (1.73 min/cm3; both, p < 0.001). Printed models helped promote visual appreciation of organ-tumor anatomy and adjacent tissues. Our mesh-work 3D thyroidal prototype reproduced glandular size/contour and tumor location, readily approximating the surgical specimen. This newly devised mesh-type 3D printing method may facilitate anatomic modeling for personalized care and improve patient awareness during informed surgical consent.

Three-dimensional (3D) printing is opening new opportunities in biomedicine by enabling creative problem solving, faster prototyping of ideas, advances in tissue engineering, and customized patient solutions. The National Institutes of Health (NIH) Library purchased a Makerbot Replicator 2 3D printer to give scientists a chance to try out this technology. To launch the service, the library offered training, conducted a survey on service model preferences, and tracked usage and class attendance. 3D printing was very popular, with new lab equipment prototypes being the most common model type. Most survey respondents indicated they would use the service again and be willing to pay for models. There was high interest in training for 3D modeling, which has a steep learning curve. 3D printers also require significant care and repairs. NIH scientists are using 3D printing to improve their research, and it is opening new avenues for problem solving in labs. Several scientists found the 3D printer so helpful they bought one for their labs. Having a printer in a central and open location like a library can help scientists, doctors, and students learn how to use this technology in their work.
