Survey on 3D Technologies: Case Study on 3D Scanning, Processing and Printing with a Model

The goal of this paper is to explain the current situation of 3D technologies. There are many sources for field specific 3D tools about their intended usage. However, there is lack of general overview of the situation in scientific or engineering society. This survey is completed without prioritizing a single industry or method. Even though the two focus points of the paper are 3D scanning and 3D printing, 3D software tools are also mentioned as they are the link between these technologies. This research was conducted as a Modeling and Identification project for Tallinn University of Technology (TalTech). The practical work was conducted as a case study to observe the real-life results. Several methods and tools were discussed during this phase. Nevertheless, some tools are examined in more detail since they were used for practical work. The physical results were having high accuracy and near-perfect versions of the scan on the software before printing.
