Lee, Cheol Ho(이철호),Hong, Sung Yeap(홍성엽) 한국전시산업융합연구원 2016 한국과학예술융합학회 Vol.24 No.-

3D printing is technology making 3D object through the process adding class materials continuously. It is expected that 3D printing technology will cause manufacturing revolution by producing a product personally according to development of internet and software technology. 3D printing technology can be applied to the whole industries such as architecture, airline industry, medical industry producing dentistry prostheses, consumer-electronics industry producing all sorts of electronic components, and even food industry using the ingredient of food. Materials of 3D printing are classified into thermoplastic, powder, resin, metal, and ceramic. Thermoplastic materials cannot put pressure fully in 3D printing process, so are bounded to get elaborate printed matters, and need various properties of different kinds of matter by problems such as particle size and distribution, particle shape, molecular weight, melting point, re-crystallization temperature, viscosity on dissolution, reactivity of laser, volatility, and containing surviving monomer and volatile matter. The 3D printing materials such as BendLay, soft PLA, and TPU are used most in 3D printing of clothes. TPU has flexibility generally, and has the strong corrosion resistance, so is thermoplastic plastics as rubber that is industrially used. This can be very flexible matter according to degree of mixing with other matters. Soft PLA is as rubber because of tightening with excellent roundness. BendLay-3D Filament is a brand name of 3D printing material of modified ABS made by Orbi-Tech. In this article, the positive situation of 3D printing of clothing industry and the 3D printing materials for textiles will be discussed. Clothing industry has tried to make existing comfortable clothing or to print soft clothing with 3D printing technology, but is at an early stage yet. Until now, clothes made by 3D printing have much inconvenience to wear in reality, but many designers and 3D machine manufactures are attracting the public’s attention about a possibility of production of 3D printed textiles. There are several needs for clothing industry using 3D printing to grow. The first need is about material. Various materials that are generally used in 3D printing at present such as general high-molecular substance, metal, and cotton are used in production of clothes. Till now, it is insufficient for these materials to be flexible, warm, and breathable as existing fabrics. Second, it should be favoring-consumer technology. It should be easy for consumers to design, change into 3D file, and do 3D printing. Third, it should be eco-friendly. The whole process from printing to materials should be eco-friendly or possible to recycle, and biodegradable substance should be used.

3D 프린팅에 대한 제조물책임의 적용 연구

李相水(Lee, Sang-Soo) 중앙법학회 2016 中央法學 Vol.18 No.2

「Three Dimensional Printing Industry Promotion Act」 legislated in December 2015 has significance as the first law that introduced Product Liability to the individual law related to ICT. It means that the Act arranged legal solution plan in case of the damage on one’s life, body, or property due to faulty product made with 3D Printing, which is advanced ICT technology. Compensation for further damage due to the defects of 3D Printing product is first, under default of obligation of 「Civil Law」 Article 390, assuming contract relation between person directly related. Second, it is under responsibility of tort 「Civil Law」 Article 750 that should prove negligence/intention of assailant regardless of contract relation between person directly related and defects liability under 「Civil Law」 Article 580. Also, there is Product Liability that applies liability without fault to compensation for damages due to product defect. The problem is that to establish defects of 3D Printing Product requires high-degree of professional ability. 3D Printing Product is developed by skilled programmers or technicians, and it is hard for normal consumers to know the complexity of 3D Printing Product combined with elaborate IT devices and electronics. Therefore, by putting liability without fault regardless of contract relation on 「Product Liability Law」, it has a different signification in the point that it can solve the existing limitation of compensation for damage due to the defects of 3D Printing Product. Especially, 3D Plan and 3D Printing software developed by software technicians run 3D Printer, and produce 3D Printing products. Because it is difficult for consumers to understand the complexity of 3D Plan, 3D Printing Software, or 3D Printer that is developed by skilled software technicians, it is urgent to relax burden of proof about causal relationship of occurrence of damage and presence of defects on 「Product Liability Law」. Therefore, when the fact confirms that the accident occurs under the exclusive control of manufacturer and the accident does not normally occur without mistake of manufacturer or third party although the product is used in normal way and the consumer receives further damage, regulation should be created that estimates further damage due to defect and accident of products occurring by the fault of the product. And it must be coincided with legislative purpose of 「Product Liability Law」. Meanwhile, as we examined before, Product Liability exemption should be made toward manufacturers of 3D printing software in the point that it enables users to judge the availability in printing software that provides source code. Also, in the case of the products that accompany high-degree of technical skills like 3D Printing and in case of conflict that occurs due to Product Liability, consumers actually have burden of raising original suit on the basis of Product Liability on 「Product Liability Law」 or 「Three Dimensional Printing Industry Promotion Act」, and due to the difficulty of defect proof unlike general products. Therefore, dispute conciliation function of 3D Printing Product Liability to 「Three Dimensional Printing Industry Promotion Act」 should be established and suspension effect of statute of limitations need to be required in order that prompt and effective solution can be made from conflict consequential to Product Liability of 3D Printing.

이정우,이인환,김호찬,최재원 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.4 No.3

Multi-material 3D printing with electrically functional materials including conducting, sensing, insulating and semiconducting materials has led to the development of smart devices such as 3D structural electronics, sensors, batteries, etc. Electronically smart devices are a hot issue in 3D printing because they can certainly benefit from 3D printing technology, providing high design flexibility and customized functions. Shape-changing materials (e.g. shape memory polymers) incorporated in 3D printing have given birth to 4D printing, where 3D printed structures change in their shapes by external stimuli (temperature, light, water, etc.). The motivation of this review paper is to discuss mutual benefits from both 3D printed smart devices and 4D printed features, which can be built in a single body. It is expected that the combination of 3D printed smart devices and 4D printing would contribute to the development of high performance, adaptability to the environment and programmable 3D smart devices, which have not yet existed. This paper has reviewed the background of 3D printing, smart device fabrication using 3D printing, development into 4D printing, and future applications of 4D printing.

3D 프린팅이 디자인 비즈니스에 미치는 영향에 관한 연구

김성익(Sheng Yi Jin),오창섭(Chang Sup Oh) 한국디자인문화학회 2014 한국디자인문화학회지 Vol.20 No.4

3D프린팅 기술이 일반화되면서 산업 환경과 소비문화에 많은 변화가 기대되는 가운데 디자인 환경에도 큰 변화가 예상된다. 제조업에서 3D프린팅을 활용한 맞춤형 소량생산 시스템은 소비자들의 개인 취향을 반영한 맞춤형 제품생산을 가능하게 하여 상당한 경제적 파급효과를 만들어 낼 것으로 보인다. 특히 모바일시대를 맞아 언제 어디서나 검색을 통해 스스로 원하는 상품에 접근이 가능해지면서 ‘틈새상품’이 중요해지는 새로운 경제 패러다임, 즉 ‘롱테일 법칙’이 점차 사회적 공감대를 형성하고 있다. 이러한 상황에서 시장수요를 충족시킬 수 있는 생산시스템과 서비스플랫폼 구축은 매우 중요하고, 그에 따라 3D프린팅과 디자인의 연관성을 이해할 필요성이 높아지고 있다. 본 연구는 3D프린팅 기술의 내용과 활용사례 분석을 토대로 이 기술이 향후 디자인 비즈니스에 어떠한 영향을 줄 수 있는지 밝히는데 그 목적이 있다. 연구방법은 문헌연구, 사례분석, 방향 제시로 구성된다. 첫째, 문헌연구를 통해 3D프린팅의 개념, 기술현황 등을 파악하였으며, 이론적 고찰을 통해 3D프린팅이 만들어갈 새로운 맞춤형 소량생산 시스템에 대한 이해를 전개시키고 있다. 둘째 3D 프린팅의 활용사례를 제조업을 중심으로 디자인프로세스, 생산영역, 소비·유통영역으로 구분하여 살펴보았다. 마지막으로 3D프린팅과 디자인의 관계성을 고찰함으로써 새로운 디자인비즈니스의 방향을 예측제시하고 있다. 최근에 3D프린팅을 활용한 복제서비스, 셀프제작소, 3D프린팅 서비스와 같은 맞춤형 서비스가 강화되면서 기존 제조업[생산 → 유통 → 소비]의 생산체계를 [소비 → 생산 → 유통]의 순서로 바뀌어 선(先)주문, 후(後)생산이라는 새로운 비즈니스모델로 전환하는 환경변화에 주목하여야 한다. 향후 3D프린팅 서비스산업은 3D프린터(장비), SNS 서비스(플랫폼), 콘텐츠(디자인)가 융합된 다양한 유통 플랫폼을 개발하여 디자인콘텐츠 유통, 3D프린팅 제작물 유통, 개발 컨설팅에 크게 기여할 것이다. 이에 대비하여 출력할 수 있는 3D디자인 콘텐츠 개발과 시스템 구축, 그리고 관련저작권 보호제도 등 3D프린팅과 디자인융합을 촉진시키는 디자인 생태계를 만들어 다양한 디자인 비즈니스 모델을 활성화시켜야 한다. The technique of 3D printing is being popularized and as a result it is expected that there will be a lot of great changes in the fields of environment and consumption culture. A small quantity production system utilized in manufacturing has made the spelling production of goods meet the taste of the consumers, which will bring large economic benefits. Now is the mobile times, and it is possible whenever and wherever to find through search the wanted products and the new economic paradigm of the crack commodities, i.e. the Long Tail will be popular trend in the society. Therefore it is very important to build production system and service platform meeting the needs of the market. The connection between 3D printing and design is more and more important. The purpose of this study is analysis of the technical contents of the 3D printing and examples of utilization and clarification to how the technique will affect the design business. This study is made of study of reference documents, analysis of utilization examples and orientations. First, through theoretical observations it has been possible to learn the concept of 3D printing and its present situation etc., and through theoretical observation it is possible to realize the new small quantity production system, which will be done by 3D printing. Second, the paper has studied the active examples of 3D printing, which are divided into design process, production, consumption, circulation etc. Finally, the study has tried to find the changes of relation between 3D printing and design and predicted the orientation of the new design business. With regards to recent rapid development of reassembling such as reproduction service, self-manufacturer, 3D printing etc. it is necessary to pay attention to the change of business environment where the existing system of production-circulation consumption is being changed into a new model of consumption-production-circulation. In the future the 3D printing service industry will develop the multiple circulation platform of combination of 3D printer (equipment), SNS service (platform), and contents (design), which will make great contribution to circulation of design contents, circulation of 3D printing products and development consulting. In view of this it is necessary to activate a multiple design business model creating a design environment which will promote combination of 3D printing and design contents with capability of output, construction of system as well as protection of related copyrights.

3D프린팅 제품/서비스 사용자 연구 - 온라인 3D프린팅 서비스 Shapeways를 중심으로 -

우숙영 ( Woo Soog Yeong ),이유진 ( Lee Yoo Jin ) 디자인융복합학회 2018 디자인융복합연구 Vol.17 No.2

본 연구는 3D프린팅 기술과 산업자체에 대한 연구에 비해, 실질적으로 사람들과의 접점이 되는 서비스와 3D프린팅 제품을 제작하는 사용자 측면에서의 연구는 부족하다는 문제의식에서 출발하였다. 연구는 기업차원이 아닌 개인이나 소상공인 차원에서의 3D프린팅(Consumer 3D Printing)으로 한정되어 진행 되었으며, 3D프린팅 서비스와 사용자들에 대한 이해를 높이기 위한 문헌연구와, 3D프린팅 제품 및 사용자 현황을 파악하기 위한 사례연구로 나누어 진행되었다. 연구결과 개인, 소상공인 3D프린팅 서비스 사용자들은 기존 산업용 3D프린팅(Enterprise 3D Printing)과 달리 부품, 시제품뿐 아니라 높은 비율로 다양한 완제품을 만들고 판매 하고 있었으며, 전문성과 소속, 제작물에 따라 분류 할 수 있었다. 이는 3D프린팅 서비스가 소수의 사용자를 벗어나 성공적으로 확산되기 위해서는 다양한 제품과 사용자 유형을 고려해야 함을 의미하며, 본 연구는 3D프린팅 서비스가 단순한 제품의 3D출력을 넘어 서비스 전반에 걸쳐 완성도 있는 제품을 생산하는데 필요한 제품과 사용자 유형을 밝혀냈다는 점에서 그 의미를 가진다. This study started from the awareness that there has been a lack of research in terms of users who are producing 3D printing products and services that are actually contact points with people, compared to research on 3D printing technology and industry itself. The study has been conducted with the limitation of 3D printing at the individual or small business level rather than at the enterprise level, and it also has been carried out by dividing it into a literature study to improve understanding of 3D printing services and users as the subject of study, and a case study to understand 3D printing products and the present condition of users. As a result of the study, 3D printing service users were making and selling a wide variety of finished products at a high rate as well as parts through the 3D printing technology and were classified according to their expertise, affiliation, and products. This means that 3D printing services need to consider various products and user types in order to spread successfully from a few users, and it can be said that this study is meaningful in that it revealed products and user types that should be considered in order to provide the help that 3D printing services need to produce products with a higher level of maturity throughout the services, beyond the 3D output of simple products.

Will 3-D Printing Technology Change the Face of Copyright of Real Estate In Singapore?

( Seow Samuel ) 건국대학교 법학연구소 2015 일감부동산법학 Vol.10 No.-

3-D 프린팅의 발명으로 인해 전 세계인들은 무엇이든지 프린터를 통해 생산할 수 있게 되었다. 이로 인해 지적 재산권과 부동산의 관계를 검토할 수 있는 기회가 마련되었다 할 수 있다. 3-D 프린팅으로 제조업의 `민주화`라는 것이 가능해지면서, 대중의 창의력을 북돋고 경제발전을 조성할 수 있는 막대한 가능성이 펼쳐지게 되었다. 3-D 프린팅 환경의 맥락에서 저작권 문제가 발생할 수 있는 것이 사실이지만, 이를 통해 설계공정과 제조공정 간의 거리가 더욱 좁혀질 수 있게 되었다. 3-D 프린팅 공정의 효율성을 제고한다면, 소량 생산의 경우에도 대량 생산의 효율성을 달성할 수 있게 된다는 점에서 업계에 완전히 새로운 기회를 제공할 수 있게 될 것이다. 저작권과 관련한 3-D 프린팅의 주요 문제는 기존의 시장에 대하여 독립적으로 광범위한 저작물의 사적 복제가 가능해지며, 이는 추적하거나, 방지 및 통제 불가한 방식으로 이루어질 것이라는 점이다. 저작권 침해의 원칙들을 다른 저작권 문제와 동일하게 3-D 프린팅에도 적용할 수 있지만, 저작권법이 3-D 디자인과 소프트웨어의 보호 범위를 어디까지로 할 것인지, 또 어떠한 행위가 침해를 구성하는지를 전부 규율하는 것은 아니다. 3-D 프린팅과 관련한 법적 쟁점의 해결을 도출하는 것은 용이하지 않다. 현 시점에서 3-D 프린팅에 관련된 흥미로운 문제점이 다양하게 발생하고 있다. 그러나 보통법(Common Law) 체계의 특성상 이러한 문제의 해결에 있어 3-D 프린팅을 직접 대상으로 하지 않는 판례에 기초하여 지침과 유사점을 도출해야 할 것이다. 결론적으로, 보다 명확한 법적 준거가 마련될 때까지는 국제 사회가 공동으로 3-D 프린팅 발전의 규범을 수립해 나가야 할 것이다. 3-D printing offers to the public the realistic possibility that anyone in the world with an access to a printer can produce any object. For this reason, it offers to the world an opportunity to examine the way we think about intellectual property and its relationship with real property. The so-called “democratization” of manufacturing that 3-D printing promises has a huge potential to unleash the creativity of the masses and foster economic growth. With all the copyright complications that may arise in the 3-D printing context, 3-D printing has the capability of bringing the design process and the manufacturing process closer together. A more efficient 3-D printing process would allow industry an opportunity it never had before, in that small-scale production can be as efficient as large scale production. The main problem with 3-D printing related to copyrights is the possibility of extensive personal manufacturing of copyrighted objects independent of established markets in ways that cannot be detected, prevented or controlled. Although the principle of copyright infringement apply to 3-D printing as they apply to other copyright issues, not all copyright laws are clear about the degree to which 3D designs and softwares are protectable and which act may constitute infringement. Many of the legal issues raise by 3-D printing do not have simple, easy answers. At this point, numerous interesting questions are starting to emerge concerning 3-D printing technology. However, the answers to these questions can only be provided by drawing guidance and analogies from cases that do not involve 3-D printing as the Common law system is wont to do. Ultimately, the burden is on the international community to set the norms on the development of 3-D printing until there is a better legal clarity.

3차원 프린터의 출력 볼륨보다 큰 물체를 출력하기 위한 인터랙티브 3차원 메쉬 편집 시스템

추창우,김갑기,박창준,최진성 한국멀티미디어학회 2016 멀티미디어학회논문지 Vol.19 No.8

3차원 프린터의 출력 볼륨보다 큰 Recently, as the public interests about the 3D printing technology are increased, various kinds of 3D printers are being released. But, they are limited to use because they cannot fabricate an object which is larger than the printer’s printing volume. To relieve this problem, we propose an interactive 3D mesh editing system for 3D printing the object that is larger than the printing volume. The proposed 3D editing system divides the input 3D mesh using the user’s line drawings defining cutting planes and it attaches various connectors. The output meshes are guaranteed to fabricate without post-processing. The printed parts can be assembled using the connectors. Our proposed system has an advantage that it can be used easily by non-professional 3D printer users.물체를 출력하기위한 인터랙티브 3차원 메쉬 편집 시스템 Recently, as the public interests about the 3D printing technology are increased, various kinds of 3D printers are being released.

ESG경영을 위한 글로벌 3D프린팅 사례 연구

천백민(Chun, Baek Min) 글로벌경영학회 2021 글로벌경영학회지 Vol.18 No.6

2005년 유엔글로벌콤팩트 (UNGC)에서 공식 용어가 된 ESG는 기업 경영을 위해서는 지키고 추구해야 하는 목표가 되고 있다. ESG 경영을 논할 때 기업의 환경 보호, 사회적 책임, 지배구조에 초점을 맞추는 과정에서 기술이 이바지하는 부분을 간과되는 측면이 있다. 4차 산업혁명 기술 중 3D프린팅이 ESG 경영에 기여할 수 있는 가능성을 확인하는 것이 본 연구의 목적이다. 이번 연구는 3D프린팅 기술이 어떻게 ESG 경영을 도울 수 있는지 제조업에서의 3D프린팅과 축산업 및 식품산업에서의 3D Food Printing으로 나누어 글로벌 사례를 연구하였다. 본 사례 연구 결과 3D프린팅은 분산 생산을 가능하게 하여 기업이 수요변화에 빠르게 대응할 수 있고, Digital Inventory를 구축할 수 있어 물류시스템을 단순화하고 탄소 배출을 줄일 수 있으며, 디자인 혁신을 통해 기업 경쟁력을 높여 스마트생산을 가능하게 함을 알 수 있었다. 3D Food Printing은 대체육을 생산하여 동물 사육에 들어가는 자원과 에너지를 줄여 축산업이 환경에 기여할 수 있게 하고, 식품산업이 비대면으로 음식을 만들고 개인 맞춤화 음식을 제공하는 차별화 전략과 함께 ESG 경영을 가능하게 한다. 이와 더불어 3D Food Printing 기술이 인류 식량 문제 해결에 도움을 줄 수 있는 사회적 기여 측면의 가능성을 발견하였다. ESG, which became an official term in the United Nations Global Compact (UNGC) in 2005, has become a goal that must be kept and pursued for corporate management. When discussing ESG management, the contribution of technology in the process of focusing on corporate environmental protection, social responsibility and governance is often overlooked. The purpose of this case study is to confirm the possibility that 3D printing among the 4th industrial revolution technologies can contribute to ESG management. This study researched global cases of how 3D printing technology can help ESG management by dividing it into 3D printing in the manufacturing industry and 3D food printing in the livestock and food industry. As a result of this case study, 3D printing enables distributed manufacturing which companies can respond quickly to changes in demand, companies to build a digital inventory so the logistics system can be simplified and carbon emissions can be reduced, and to innovate design process therefore competitiveness can be improved and smart manufacturing is available. 3D Food Printing makes the livestock industry contribute to the environment by reducing the resources and energy that goes into animal breeding via alternative meat production, and the food industry produce untact food and personalized food which enables companies a differentiation strategy and ESG management. In addition, the possibility of social contribution was discovered which the 3D Food Printing technology can help solve the human food problem.

SNA를 이용한 물류산업의 3D Printing 연구 동향분석

김유나(Kim, Yu-Na),김현진(Kim, Hyun-Jin),손일명(Sun, Yi-Ming),여기태(Yeo, Gi-Tae) 한국물류학회 2022 물류학회지 Vol.32 No.2

물류산업에서 3D Printing이 가지는 환경적, 경제적 가치에도 불구하고 물류분야에 초점을 맞춰 전반적인 연구 트렌드를 파악한 연구는 거의 이루어지지 않은 상태이다. 이러한 측면에서 본 연구에서는 물류분야에서 3D Printing을 주제로 한 연구를 종합하여 연구 동향을 파악하는 것을 연구의 목적으로 하였다. ‘3D Printing’과 ‘Logistics’ 키워드를 사용한 해외학술연구를 대상으로 물류분야 내의 3D Printing 연구를 중심으로, 가장 많이 사용된 키워드를 사회 네트워크 분석(Social Network Analysis, SNA) 방법론을 활용하여 파악하였다. Science Direct를 비롯한 Scopus, Emerald Insight, Springer, Taylor & Francis의 학술데이터베이스에서2010년부터 2021년 4월까지 총 11년간 119편의 논문을 분석에 활용했다. 연구의 결과는 다음과 같다. 첫째, 키워드간 연결 횟수를확인한 결과, 3D Printing을 이용한 적층제조 방식과 Industry 4.0에서 제시된 기술을 활용한 물류분야의 적용 및 개선에 연구가 집중되고 있음을 확인할 수 있다. 둘째, 분석대상 119편 논문의 키워드 간 매개성을 분석한 결과, 대부분 키워드들이 Industry 4.0를통해서 3D Printing에 연결되는 것을 확인하였다. 이는 키워드 Industry 4.0에서 제시된 혁신적인 기술을 활용하여 다양한 물류산업에 접목을 시도하는 연구가 가장 활발하다는 것을 나타낸다. 셋째, 전체노드의 중심성을 반영하여 계산하는 고유벡터중심성 결과에서 물류 키워드는 각각 3위 (Supply Chain: 0.242) 및 4위 (Logistics: 0.240)로 상승한 것을 확인할 수 있다. 이를 통하여 3D Printing 관련연구는 물류분야 연구와 밀접하게 진행되고 있으며, 특히 공급사슬망의 최적화 및 보완 역할에 3D Printing이 유용하게 접목되고 있음을 확인할 수 있다. Despite the environmental and economic value of 3D printing in the logistics industry, no research has thus far focused on the field of logistics to identify its overall research trend. Therefore, the present study aims to understand the research trends in logistics by incorporating studies on 3D printing in the field of logistics. The most commonly used keywords surrounding 3D printing in the field of logistics were identified using the social network analysis on academic research that used the keywords “3D printing”and “logistics”. The 110 papers published for a 11-year period from 2010 to April 2021 were retrieved from the academic databases of Science Direct, Scopus, Emerald Insight, Springer, and Taylor & Francis, and then were utilized for analysis. The results of the study are as follows. First, as a result of checking the number of connections between keywords, it can be confirmed that research is focused on applying and improving the additive manufacturing method using 3D printing and the logistics field using the technology presented in Industry 4.0. Second, as a result of analyzing the mediating between keywords of the 119 papers to be analyzed, it was confirmed that most of the keywords were connected to 3D printing through Industry 4.0. This indicates that research that attempts to graft into various logistics industries is the most active by utilizing the innovative technology presented in the keyword Industry 4.0. Third, in the eigenvector centrality result calculated by reflecting the centrality of all nodes, it can be seen that the logistics keyword rose to 3rd (Supply Chain: 0.242) and 4th (Logistics: 0.240), respectively. Through this, research on 3D printing is being conducted closely with research in the logistics field, and in particular, 3D printing is useful for the optimization and supplementation role of the supply chain.
