The main goal of the project is to investigate the possible ways of introducing the additive technologies, to study the peculiarities of the layer wise synthesis process when producing foundry patterns and defining basic parameters which influence the quality of the produced parts. Based on the analysis of the results of activities aimed at the development of three-dimensional printing in Kazakhstan, highlighted the alleged problems of the successful implementation of additive technologies in the economy and in education particularly. In article the scheme of the existence and development of new technologies and the role of government’s support in the process is given. The results of data analysis from the Internet shows that there is a sufficient number of three-dimensional modeling laboratories, but it is mostly commercial service companies in the field of three-dimensional printing. The key factor in the growth of any economy is to organize an effective system of technology transfer and its further improvement.

Before the COVID-19 pandemic erupted onto the world stage, a new narrative was apparently beginning to emerge about the impact of i4.0 and new technologies in general, and three-dimensional printing in particular, on the future of work and employment. This was to have particular geographical implications for the manufacturing sector in particular. Proponents of i4.0 also suggested that this process, particularly in manufacturing, would promote the re-emergence of patterns of clustering. Developments in advanced manufacturing, particularly three-dimensional printing, would accelerate and reinforce these tendencies. This article looks at the role that three-dimensional printing is supposed to play in the new world, and in particular, critically evaluates its role in reinforcing the trend towards deglobalisation on the one hand, and, on the other, new clusters of manufacturing industry.

Modeling technologies and 3D printing are being introduced into many branches of production, supplementing or displacing traditional methods and provide new results in various fields. Research and development based on the use of three-dimensional printing did not bypass tactile cartography, which is quite expected, given the very essence of tactile perception – the sense of touch of the surface under study. The article discusses the possibility of using 3D printing for the font design of tactile maps intended for people with limited visual function. The author presents the results of a study on the perception of Braille created with a 3D printer. An algorithm developed for converting textual and numerical data from fields in the attribute tables of geographic information system bases into inscriptions of objects executed in Braille was.

Dimensional Printing

Three-dimensional printing has several significant advantages over traditional methods of production: simplification and acceleration of the production process, versatility, low cost and a few others. As a result, additive technologies have quickly become a highly promising area with great potential in many areas of human activity, finding more and more points of application. Medicine is no exception. The development of three-dimensional printing in the field of medicine can not only solve a few pressing health problems, but also stimulate the progress of technology. To date, three-dimensional medical printing is used in the following areas: individual prostheses both temporary and permanent wear, surgical instruments, simulation manuals for training medical students and preoperative training of surgeons. Of interest is the joint application of additive technologies with cellular technologies – bioprinting. Despite its great potential, this activity is not sufficiently regulated, which is a serious obstacle to its development. The introduction into practice of the principles proposed in this work of the device and functioning of a specialized service – laboratory of additive medical production – should solve this problem and contribute to the rapid development of medical three-dimensional printing in the Russian Federation.

Complex Parts

Three-dimensional printing technologies allow for the fabrication of complex parts with accurate geometry and less production time. When applied to biomedical applications, two different approaches, known as direct or indirect bioprinting, may be performed. The classical way is to print a support structure, the scaffold, and then culture the cells. Due to the low efficiency of this method, direct bioprinting has been proposed, with or without the use of scaffolds. Scaffolds are the most common technology to culture cells, but bioassembly of cells may be an interesting methodology to mimic the native microenvironment, the extracellular matrix, where the cells interact between themselves. The purpose of this review is to give an updated report about the materials, the bioprinting technologies, and the cells used in cancer research for breast, brain, lung, liver, reproductive, gastric, skin, and bladder associated cancers, to help the development of possible treatments to lower the mortality rates, increasing the effectiveness of guided therapies. This work introduces direct bioprinting to be considered as a key factor above the main tissue engineering technologies.

Purpose. Analysis of methods of manufacturing centrifugal blades by 3D printing methods on the example of a modernized cooling system of the AI-450M engine of the Mi-2MSB helicopter. Research methods: calculation method of finite elements, analytical. Results. Studies have shown that the use of layer-by-layer printing technology of the centrifugal wheel of the cooling system provides the following opportunities and improvements: - reduce the percentage of rejection of finished products by 8–9 times; - reduce material consumption by 300–400 %; - increase the speed of production, experiments and testing the manufacture of working elements through the development of new technologies for rapid production (rapid fabrication); - easy printing of previously “impossible” geometry. The analysis of possible types of manufacturing of  working centrifugal wheel and the calculated estimation of thermodynamic parameters in the course of step-by-step drawing of layers of metal is carried out. The problem of a large percentage of defects in the process of classical-mechanical milling of blades was solved by changing the type of production to additive one. Scientific novelty. In today's world, the spread of CAD / CAM / CAE / PLM technologies and the accumulation of a wide library of materials open up a large number of new and more efficient, in terms of economy and quality, methods of manufacturing components and units. Following the example of such giants in the production of aircraft engines as Rolls-Royce Motor, General Electric and Pratt & Whitney, it is clear that the use and development of the latest methods of three-dimensional printing is appropriate. Practical value. The obtained results are important in the further process of production and modernization ofMi-2 helicopter of all modifications with the latest engines, as well as for projects for the development of helicopter construction in Ukraine - МСБ-2 “Hope”, МСБ -6 “Otaman”, МСБ-8 and others. The ability to increase the efficiency of manufacturing the main working elements - blades allows you to reduce the cost of components, their further repair, operation. The most important factor is to increase reliability, as in the manufacture reduces the likelihood of defects, which will not be detected at the stages of intermediate and final control.

Ossifying fibroma (OF) is a rare, benign, fibro-osseous lesion of the jawbone characterised by replacement of the normal bone with fibrous tissue. The fibrous tissue shows varying amount of calcified structures resembling bone and/or cementum. The central variant of OF is rare, and shows predilection for mandible among the jawbone. Although it is classified as fibro-osseous lesion, it clinically behaves as a benign tumour and can grow to large size, causing bony swelling and facial asymmetry. This paper reports a case of large central OF of mandible in a 40-year-old male patient. The lesion was treated by segmental resection of mandible. Reconstruction of the surgical defect was done using avascular fibula bone graft. Role of three-dimensional printing of jaw and its benefits in surgical planning and reconstruction are also highlighted.
