<p>Unconventional methods of modern materials preparation include additive technologies which involve the sintering of powders of different chemical composition, granularity, physical, chemical and other utility properties. The technology called Rapid Prototyping, which uses different technological principles of producing components, belongs to this type of material preparation. The Rapid Prototyping technology facilities use photopolymers, thermoplastics, specially treated paper or metal powders. The advantage is the direct production of metal parts from input data and the fact that there is no need for the production of special tools (moulds, press tools, etc.). Unused powder from sintering technologies is re-used for production 98% of the time, which means that the process is economical, as well as ecological.The present paper discusses the technology of Direct Metal Laser Sintering (DMLS), which falls into the group of additive technologies of Rapid Prototyping (RP). The major objective is a detailed description of DMLS, pointing out the benefits it offers and its application in practice. The practical part describes the production and provides an economic comparison of several prototype parts that were designed for testing in the automotive industry.</p>

At its core, engineering technical design is the process of taking a concept to creation. In order to achievesuccessful technical design a student must combine their idea or vision of a solution (function) with a visualization of thepart/assembly (form) -- referred to henceforth as vision-ization. Teaching technical design to a large first-year class ofengineering students presents a number of challenges, but perhaps the most significant is the rapid change of the toolsused in engineering technical design. To be clear, the tools themselves are not the challenge, as the students generallyhave no trouble mastering the tools. The challenge lies in the teaching and ultimately the learning objectives; at aUniversity level the fundamental question is what pedagogical benefit does a tool provide without the knowledge to applyit? As the tools have advanced, the students (and the instructors) find themselves further from the design process resultingin course topics perceived as disconnected or without relevance. In 2006 McMaster University's first-year engineeringprogram departed from the traditional method of teaching engineering design, which was heavily focussed on form, toestablish design function as the primary objective of the course. With a yearly enrolment near 1000 students, thescalability of teaching and evaluating design function was implemented using a customized simulation and visualizationtool. The simulation was extended to the logical use of rapid prototyping machines (3D-printers) for physical creation andtesting. This paper will present the author's initial analysis of the link between pure visualization, applied visualization,and success in functional design via rapid prototyping..

Innovation Cycle

Introduction. The methodological systems of preparation for innovative engineering activity involve the involvement of students in all stages of the innovation cycle, including obtaining an intangible innovative product. However, the inability to obtain in students a material innovative product reduces the effectiveness of the preparation of these systems. The purpose of this study is to create a methodical system for preparing students for innovative research activities based on their involvement in all stages of obtaining a material innovative product using additive technologies. Materials and Methods. For writing the article the authors used the main points of the integrated approach to learning (integration of theoretical and practical training of innovative research activities and interdisciplinary integration of various branches of science (pedagogy, mathematical modeling, 3D modeling, additive technologies, innovation). Results. The methodical system of training students of technical higher education institution has been created and implemented, ensuring their involvement in all stages of the innovation cycle due to the use of rapid prototyping technologies. The effectiveness of technologies is confirmed by the results of the pedagogical experiment. Discussion and Conclusions. The performed researches allowed to create a methodical system for training students of technical universities of innovative research activities based on rapid prototyping technologies. This method significantly improves the effectiveness of training. It ensures the participation of students in all stages of obtaining a material innovative product: during the study of the course, and during classroom sessions. This method was developed and tested for the implementation at National Research Ogarev Mordovia State University. It provides the practical significance of the study considered in the article. Further development of the material presented in the article can be related to the expansion of the infrastructure of the Rapid Pro university center for designing and prototyping and attracting students to manufacturing industrial products.

Regarding the functional requirements for smart substation in fault recorder, this paper introduced μC / OS-II, an embedded real-time multitasking operating system as the functional design. The program works with the embedded operating system, the state machine theory and new methods for embedded development, whilst tasking full use of the advantages of such functions as task scheduling, message queues, etc., aiming to achieve a fault recorder function of intelligent substation. More than taking care of the difficulty of programming, it could improve the program reliability and portability. The program has been applied in an intelligent substation protection in centralized control unit, which has brought back a good fault recorder performance. On this basis, more functions can be integrated, including network log analysis, state estimation, etc., in order to truly meet the application requirements of the smart substations.

The slowscan and TV signal of the Philips SEM 505 and the signal of a TV camera attached to a Leitz fluorescent microscope, were digitized by the data acquisition processor of a Masscomp 5520S computer, which is based on a 16.7 MHz 68020 CPU with 10 Mb RAM memory, a graphics processor with two frame buffers for images with 8 bit / 256 grey values, a high definition (HD) monitor (910 × 1150), two hard disks (70 and 663 Mb) and a 60 Mb tape drive. The system is equipped with Imaging Technology video digitizing boards: analog I/O, an ALU, and two memory mapped frame buffers for TV images of the IP 512 series. The Masscomp computer has an ethernet connection to other computers, such as a Vax PDP 11/785, and a Sun 368i with a 327 Mb hard disk and a SCSI interface to an Exabyte 2.3 Gb helical scan tape drive. The operating system for these computers is based on different versions of Unix, such as RTU 4.1 (including NFS) on the acquisition computer, bsd 4.3 for the Vax, and Sun OS 4.0.1 for the Sun (with NFS).
