The application of 3D technology increases every day by discovering new ways of usage, which can make everyday life easier. It is most used in production of individualized items that become more accessible and fully customized to personal needs. 3D technologies such as 3D scanning, 3D modelling and additive technologies (3D printing) are used in various areas of human activity such as medicine, architecture, the movie industry, etc. In the clothing’s industry, 3D scanning the human body is digitized, which is after that used in computer software packages for custom-made clothing. Except for the fashion industry, there is a need for individualized protective work clothing and equipment production in other industries as well. The possibility of applying new technologies such as 3D scanning and 3D modelling of protective elements that can be made by using 3D printers is presented in this paper. In order to design a field hockey chest protector, male and female subjects were scanned using a 3D body scanner in several different positions specific to the sport. The chest protector was constructed and modeled based on the digitalized images. Software packages were used which enable point clouds preparation of the digitalized human body for constructing the protector, its modelling and preparation of virtually designed protectors for 3D printing. An individualized chest protector is modeled using a software program called Bender. The protector is integrated into the clothing item, completely follows the body shape and provides the necessary protection.

To elucidate the mechanism that the software Gemagic Studio and 3D printer have an important role in repairing and copying the ancient cultural relics and the damaged sculpture, we take the damaged sculpture, Sissi, as the example, repaired it based on reverse engineering, 3D scanning technology and modern 3D printing technology. In the process of research, we obtain the point data of it, using reverse engineering software Gemagic Studio for the noise removing, compaction, hole filling, surface repair, error ratio and so on. And then import the 3D printer for 3D printing. At the last, the precise entity model proved that we have a wonderful experiment.

Reverse engineering plays a significant role in rebuilding of a product. This suggests a situation arranged for reverse engineering of turbine blade used in aero engine components. It is the process that designs by using point cloud data to get CAD models. Reverse Engineering is a method for creating CAD model of physical parts whose designs are not available or fractured or damaged parts by digitizing a persisting prototype, reverse engineering creates a computer model by applying 3D scanning. In this paper it is for reproducing the geometries of aero engine physical components i.e. turbine blade in digitizing process through 3D Scanning and CMM Inspection. Complete transformation of physical data into CAD models by applying modern measuring machines and with its integrated software (Creo 2.0) extraction of information about geometry to develop the part models. CMM inspection & reverse engineering software be located active to evaluate any dimension deformation. The deviation in the dimension is taken into attention as evaluating characteristics. The error analysis of some features between 3D scan data, CMM, CAD model and MESH data are performed. The deviation between scan data, CAD model & CMM are within the suitable limits and deformation between CAD model & MESH data are within -0.1 to +0.1mm. The CAD model generated is within suitable criteria i.e., 30 microns. Parts which require to reverse engineered. After completion of the CAD model 3D printing development is done.

Medical Imagery

In the last years, cardiovascular diagnosis, surgical planning and intervention have taken advantages from 3D modelling and rapid prototyping techniques. The starting data for the whole process is represented by medical imagery, in particular, but not exclusively, computed tomography (CT) or multi-slice CT (MCT) and magnetic resonance imaging (MRI). On the medical imagery, regions of interest, i.e. heart chambers, valves, aorta, coronary vessels, etc., are segmented and converted into 3D models, which can be finally converted in physical replicas through 3D printing procedure. In this work, an overview on modern approaches for automatic and semiautomatic segmentation of medical imagery for 3D surface model generation is provided. The issue of accuracy check of surface models is also addressed, together with the critical aspects of converting digital models into physical replicas through 3D printing techniques. A patient-specific 3D modelling and printing procedure (Figure 1), for surgical planning in case of complex heart diseases was developed. The procedure was applied to two case studies, for which MCT scans of the chest are available. In the article, a detailed description on the implemented patient-specific modelling procedure is provided, along with a general discussion on the potentiality and future developments of personalized 3D modelling and printing for surgical planning and surgeons practice.

AbstractDespite the very rapid technological development, the general concept of mechanical devices has not changed. Still, the most common element of these devices are gears, whose range of use is very wide. There are both technological and historical considerations for the reconstruction of gears and other elements. In particular, this applies to spare parts for technical facilities that are not available on the market or service costs are too high. Contemporary reconstruction is called Reverse Engineering, which offers tools that allow transformation of an existing object through a virtual model into the final real product. Modern production engineering is based on innovative CAD – Computer Aided Designed design methods and computer-aided manufacturing technologies, CAM – Computer Aided Manufacturing. The rapid development of 3D CAD systems has led to the development of solutions to obtain the designed object, already at the development stage. Such a solution is the Rapid Prototyping method, designed for fast, precise and repeatable production of machine components. Widespread use and growing interest in the use of additive printing influenced the development of this technology. The purpose of the article is to present the practical application of the Reverse Engineering method and 3D printing in the reconstruction of gears. The object of research is the real gear, which has been reconstructed using Reverse Engineering and 3D printing. The article presents the basic assumptions of the methods used and the methodology for conducting reconstruction work. FDM (Fused Deposition Modeling) technology was used for the research. The results obtained are a real example of the practical application of the presented methods. At the same time, they create great opportunities for their wider use.
