  • The Fourth Industrial Revolution has emerged, and technologies of various industries are being converged, compounded, or clouded computing, mobile, or big data. The emergence of a variety of skills and new jobs to match them is bringing the public out of the education and occupation of traditional metal crafts. In this change, craft education should find and study the education method suitable for the present times, and apply it to the educational field to raise public interest and revival. To this end, we will investigate the cases of education in other industries where new materials or technologies have been introduced, and use them in education of traditional metal craft techniques. In addition, we will investigate various cases and features of 3D printing technology and use it for education in craft techniques that have limited time, space and resources.

  • 현재 4차 산업혁명이 사회에 던지는 화두는 다양하다. 첫째, 소프트웨어 중심 사회이다. 빅 데이터, 인공지능 기술 등이 다양한 분야와 결합하고 그 중심에는 소프트웨어가 있다. 앞으로 소프트웨어 교육이 필수적이고 강화되어야 할 이유다. 둘째, 생산과 소비가 결합된다는 것이다. 즉, 더 이상 소비자가 수동적인 소비자로만 남지 않으며, 획일화된 제품과 서비스에 흥미를 느끼지 않고, 소비자가 직접 자신이 구매할 제품 생산과 판매에 관여하는 '프로슈머(prosumer)' 필요한 물건을 직접 만드는 D.I.Y.(Do It Yourself), 3D 프린팅 등이 새로운 소비 방식을 대표한다[3]. 이에 메이커 운동이 떠오르고 있고, 메이커에 대한 관심이 커지고 있다. 우리나라는 2015 개정 교육과정을 통해 소프트웨어 교육을 강화했다. 초등학교에서는 5~6학년 실과 교과의 정보 관련 단원이 ICT활용 중심에서 소프트웨어 기초 소양 내용 중심으로 개편되었다[1]. 아직 교육과정이 시행되기 전이지만 선도학교나 연구학교를 통해 진행된 소프트웨어 교육을 보면 기능을 익히는 프로그래밍 교육이 주류를 이루고 있고, 이래서는 다양하고 창의적인 결과물을 도출할 수 없다. 이를 해결하기 위해서는 디자인 사고를 도입할 수 있다. 디자인 사고는 인간을 관찰하고 공감하여 소비자를 이해한 뒤, 다양한 대안을 찾는 확산적 사고와 주어진 상황에 최선의 방법을 찾는 수렴적 사고의 반복을 통하여 혁신적 결과물을 도출하는 창의적 문제 해결 방법 중 하나이다[5]. 따라서 본 연구에서는 초등학생들의 소프트웨어 교육을 위한 디자인 사고 기반 메이커 교육 프로그램을 개발하고자 한다.

  • The braking force for a train is generally provided by compressed air. The pressure valve system that is used to apply appropriate braking forces to trains has a complex flow circuit. It is possible to make a channel shape that can increase the flow efficiency by 3D printing. There are restrictions on the flow shape design when using general machining. Therefore, in this study, the compressed air flow was analyzed in a pressure valve system by comparing flow paths made with conventional manufacturing methods and 3D printing. An analysis was done to examine the curvature magnitude of the flow path, the diameter of the flow path, the magnitude of the inlet and reservoir pressure, and the initial temperature of the compressed air when the flow direction changes. The minimization of pressure loss and the uniformity of the flow characteristics influenced the braking efficiency. The curvilinear flow path made through 3D printing was advantageous for improving the braking efficiency compared to the rectangular shape manufactured by general machining.

  • General phantom for practical X-ray photography Practical phantom is an indispensable textbook for radiology, but it is difficult for existing commercially available phantom to be equipped with various kinds of phantom because it is an expensive import. Using 3D printing technology, I would like to make the general phantom for practical X-ray photography less expensive and easier. We would like to use a skeleton model that was produced based on CT image data using a 3D printer of FDM (Fused Deposition Modeling) method as a phantom for general X-ray imaging. 3D slicer 4.7.0 program is used to convert CT DICOM image data into STL file, convert it to G-code conversion process, output it to 3D printer, and create skeleton model. The phantom of the completed phantom was photographed by X - ray and CT, and compared with actual medical images and phantoms on the market, there was a detailed difference between actual medical images and bone density, but it could be utilized as a practical phantom. 3D phonemes that can be used for general X-ray practice can be manufactured at low cost by utilizing 3D printers which are low cost and distributed and free 3D slicer program for research. According to the future diversification and research of 3D printing technology, it will be possible to apply to various fields such as health education and medical service.

  • The 3D printing technology, which started from the patent registration in 1986, was a technology that did not attract attention other than from some companies, due to the lack of awareness at the time. However, today, as expiring patents are appearing after the passage of 20 years, the price of 3D printers have decreased to the level of allowing purchase by individuals and the technology is attracting attention from industries, in addition to the general public, such as by naturally accepting 3D and to share 3D data, based on the generalization of online information exchange and improvement of computer performance. The production capability of 3D printers, which is based on digital data enabling digital transmission and revision and supplementation or production manufacturing not requiring molding, may provide a groundbreaking change to the process of manufacturing, and may attain the same effect in the character merchandise sector. Using a 3D printer is becoming a necessity in various figure merchandise productions which are in the forefront of the kidult culture that is recently gaining attention, and when predicting the demand by the industrial sites related to such character merchandise and when considering the more inexpensive price due to the expiration of patents and sharing of technology, expanding opportunities and sectors of employment and cultivating manpower that are able to engage in further creative work seems as a must, by introducing education courses cultivating manpower that can utilize 3D printers at the education field. However, there are limits in the information that can be obtained when seeking to introduce 3D printers in school education. Because the press or information media only mentions general information, such as the growth of the industrial size or prosperous future value of 3D printers, the research level of the academic world also remains at the level of organizing contents in an introductory level, such as by analyzing data on industrial size, analyzing the applicable scope in the industry, or introducing the printing technology. Such lack of information gives rise to problems at the education site. There would be no choice but to incur temporal and opportunity expenses, since the technology would only be able to be used after going through trials and errors, by first introducing the technology without examining the actual information, such as through comparing the strengths and weaknesses. In particular, if an expensive equipment introduced does not suit the features of school education, the loss costs would be significant. This research targeted general users without a technology-related basis, instead of specialists. By comparing the strengths and weaknesses and analyzing the problems and matters requiring notice upon use, pursuant to the representative technologies, instead of merely introducing the 3D printer technology as had been done previously, this research sought to explain the types of features that a 3D printer should have, in particular, when required in education relating to the development of figure merchandise as an optional cultural contents at cartoon-related departments, and sought to provide information that can be of practical help when seeking to provide education using 3D printers in the future. In the main body, the technologies were explained by making a classification based on a new perspective, such as the buttress method, types of materials, two-dimensional printing method, and three-dimensional printing method. The reason for selecting such different classification method was to easily allow mutual comparison of the practical problems upon use. In conclusion, the most suitable 3D printer was selected as the printer in the FDM method, which is comparatively cheap and requires low repair and maintenance cost and low materials expenses, although rather insufficient in the quality of outputs, and a recommendation was made, in addition, to select an entity that is supportive in providing technical support.

  • 3D printing has the advantage of providing opportunities for individuals to truly realize their creativity. An increasing number of people want to take advantage of this feature but they have lack opportunities for suitable printing training and struggle with problems with incorrect printing methods. Therefore, the lowered print quality lowers the interest of the user, and the 3D printer is not used gradually. In this study, we directly operate the device by identifying and analyzing the problems occurred to solve malfunctions of 3D printers and improve the convenience for user. In particular, we are conducting research on solving and mitigating problems with seating, stringing and nozzle clogging. In addition, the method of reducing material consumption and shortening the printing time was considered through experiments on the functions of 3D printers. Finally, by solving the printing problem that occurs frequently during 3D printing, it was possible to obtain a printed product with a complete appearance and improved convenience.

  • This paper is a study on the digitization of an analog 3D pen. The term digital implies features such as homeostasis, transformability, combinability, reproducibility, and convenience of storage. One device that produces a combination of these digital characteristics is a 3D printer, but its industrial use is limited due to low productivity and limitations with materials and physical characteristics. In particular, improvements are required to use 3D printers, such as better user accessibility owing to expertise and skills in modeling software and printers. Complementing this fact is the 3D pen, which is excellent in portability and ease of use, but has a limitation in that it cannot be digitized. Therefore, in order to secure a digitalization capability and ease of use, and to secure the safety of printing materials that pose controversial hazards during the printing process, research problems and alternatives have been derived by combining food, and digitization was demonstrated with a newly developed 3D pen. In order to digitize the 3D pen, a sensor in a structured device detects the motion of an analog 3D pen, and this motion is converted into 3D data (X-Y-Z coordinate values) through a spatial analysis algorithm. To prove this method, the similarity was confirmed by visualization using MeshLab version 1.3.4. It is expected that this food pen can be used in youth education and senior healthcare programs in the future.
