  • The type printing of first Ch'ing dynasty term in China is worthy to be studied because the type printing during that period included metal type, wood type, and clay type as well as the development phase was similar to Chosun dynasty culturally and technologically. This paper studied typography during the first Ch'ing dynasty term, including Shunzhi(1662-1722), Yongaheng(1723-1735), Qianlong(1736-1795), Jiaqing(1796­1820) period. The main results of the study is as follows. 1. The main body of type printing was bookstore, lecture-hall, and individual as well as the royal court that is the central government. 2. The content of type edition covers classics, history, philosophy, and literary works. Specifically, even though Wuyingdienjuzhenban series is excluded, the content includs study of the classics, class of the history, class of the philosophy, literature works that include collection works and novel and government official bulletin. 3. The printing technique of bronze type was very popular In Beijing. Jiangsu, and Taiwan. It's scale and production technique was more elaborate than in Ming dynasty. 4. Wood type was very popular in Beijing, Jiangsu, Zhejiang, Anhui, Sichuan, and Fujian. In addition to wood type, chinese ware type was applied to book printing in Shandong. However, most of them were wood type and they were used after Qianlong period. 5. The production technique of type was skilled enough to present the fine view of a style of type. The typesetting technique was improved as much as woodblock printing. With regard to the making technology of Chinese ink, the light and darkness of chinese ink was not even sometimes. But, the technology was improved significantly when comparing with the failure experience of printing that chinese ink was not developed in early type invention. 6. In case that the book was printed in bookstore with the intention of profit and the number of book was large, the proofreading attitude was rough. However, overally, it was made correction carefully applying the various methods of proofreading. 7. The support of government made a great contribution in the area of all printing technology, including production, typesetting, and brushing of type.

  • 3D printing technology, also known as additive manufacturing(AM), has not been actively used in the clothing industry despite its potential for economic, environmental, and labor efficiency. Therefore, this study aims to propose a new 3D printing method for the clothing industry, which will be more readily accessible. This roll-type printing method can print wide-sized patterns at once using a 3D modeling program and a FDM 3D printer and help overcome the limitations imposed by the size of the printer. Then, to demonstrate the practical application cases of this printing method, bags of three designs were developed. Prior to product development, a thickness test was performed for stable printing using TPU(Thermoplastic Poly Urethane) filament, and a thickness of 0.45 mm was found to be most suitable for it. Next, the time efficiency test showed that the roll-type printing method takes less time compared to the general printing method in printing wide-sized patterns. Based on these tests, three bags, , and , were developed to confirm the suitability of the roll-type printing method for product development. The advantages of 3D roll-type printing can lie in overcoming of the spatial limitation, and the environmental sustainability as it can reduce waste from the production process. This study is significant in that it presents a new 3D printing method to improve the space limitations and time inefficiency of 3D printers.

  • The development of three-dimensional (3D) printing technology is bringing new innovations to various fields such as health care, architecture, and fashion. 3D printing can be manufactured to suit the size of the consumer's body, modify the design to meet their tastes, and produce small quantities of various products. Therefore, 3D printing in the field of fashion has great potential. The purpose of this study was to investigate various application models of 3D printing for fashion design and analyze their characteristics after developing the fashion garment samples. First, the background of 3D printing was reviewed then, fashion designed by a 3D printing application was analyzed. As a result, four types of 3D printing applications were developed: object-attached, linkage, kinematics, and assembly. The object-attached type was the method of printing 3D material as an object in the intended shape and form and was attached to the garment by sewing. The linkage type referred to printing 3D material in small pieces of certain shapes that could be linked. The kinematics type was structures with hinges that could flex to fit the human body. The assembly type referred to developing 3D materials in female and male pieces such as nuts and bolts. By providing the advantages, disadvantages, trial-and-errors, and challenges of the 3D printing fashion design process, this study contributes to the effective applications and possibilities of future design.

  • 기존의 p-type 태양전지 공정과 유사한 공정으로 제작되는 n-type $ALU^+$태양전지는 후면에 Al을 screen printing하여 emitter층을 형성한 구조이다. screen printing은 공정의 단순화와 제조 단가의 저비용으로 인해, metalization 공정에서 많이 쓰이고 있다. 본 연구에서는 양산 가능한 n-type $ALU^+$태양전지 제작을 위해, 후면 Al emitter 층을 single, dobule, triple로 변경하며 Al의 양을 가변하였고, 그에 따른 특성의 변화를 연구하였다. screen printing 횟수가 변경된 후면 Al emitter 층의 특성은 DIV와 LIV 측정을 통해 분석하였다. 실험 결과 Al을 single printing 하였을 때보다, double, triple printing을 통하여 Al의 양을 증가하였을 때, DIV 데이터에서 직렬저항(Rs)가 $24.44{\Omega}/cm^2$에서 $0.31{\Omega}/cm^2$으로 감소하였고, 단락전류(Jsc)는 1.26mA/$cm^2$에서 37.7mA/$cm^2$으로 약 300% 증가한 것을 확인할 수 있었다. 프린팅 횟수에 따른 LIV 데이터의 Fill Factor를 분석하게 되면, double printing이 64.35%로 54.75%의 triple printing보다 약 1.17배 더 향상된 것으로 확인하였다. 이러한 결과를 바탕으로 후면 Al emitter 형성시에 Al의 양이 적절하지 못한 이유로, Al emitter가 제대로 형성되지 못하거나 과하게 형성되면, 태양전지 내부에 누설 저항의 변화와 누설 전류의 증가로 인해, 단락전류(Jsc)와 Fill Factor 감소의 주요 원인이 된다는 것을 확인할 수 있었다.

  • Material extrusion (ME)-type 3D printing is the most popular among the 3D printing processes. In this study, the cross-section morphologies of ME-type 3D printing manufactured specimens were observed with respect to the thermal properties of the material. The cross-section morphology of a specimen is related to the deposition strength, and the outside profile of the cross-section is related to the surface roughness. The filaments used in this study, with different thermal conductivities, were the acrylonitrile-butadiene-styrene (ABS), the high impact polystyrene (HIPS), the glycol-modified polyethylene terephthalate (PETG), and the polylactic acid (PLA). The cross-sections and the surfaces of the 3D manufactured specimens were examined. In ME-type 3D printing, the filaments are extruded through a nozzle and they form a layer. These layers rapidly solidify and as a result, they become a product. The thermal conductivity of the material influences the cooling and solidification of the layers, and subsequently the cross-section morphology and the surface roughness.

  • 3D printing is attracting attention from all industries as it enables the development of personalized product design to meet consumer needs by establishing a mutual connection system between production, management and consumers. However, there are still limitations to applying them as apparel materials, and research on the recognition of 3D printing or the preference for fashion products is needed to actually commercialize 3D printing in the fashion industry. In this study on the development of various product designs using 3D printing technology in the fashion industry, an analysis of 255 questionnaires was conducted to determine the preferences and purchase intention trends of fashion product design using 3D printing for college students. Data analysis was performed with IBM SPSS Statistics (V.24). 'Fashion sensitive pursuit', 'Individuality & brand pursuit' and 'Functional convenience' was interested in fashion accessories using 3D printing technology and customized fashion apparel products using 3D printing. 'Functional Convenience-oriented' and 'Practical Purchasing-oriented' type showed that the functionality and durability of products made using 3D printing technology were important. And 'Individuality pursuit' type indicated that design and applied materials were important when producing products using 3D printing technology.
