3D printing has the unique advantage of the ability to customize freeform products even in small quantities. It was recently applied successfully in the node connection system for the irregular shaped glass design of Gwanggyo Galleria Department Store. This was achieved by applying 3D printing technology for an innovative smart node design. The novel system offers flexibility to address various design challenges in addition to maximizing construction quality and reducing construction period. In this paper, we aim to examine the use of 3D printing based innovative technologies in the construction industry. With this aim in mind, we present the case of the Gwanggyo Galleria Department Store's smart nodes. The key objective of this study is creating awareness in the construction industry of the need to utilize fourth industrial revolution technology in architecture.

With the advent of the 4th industrial era and the development of digital technologies such as artificial intelligence (AI), metaverse, 3D printing, and 3D virtual wearing systems, the fashion industry continues to attempt to use digital technology and introduce it into various areas. The purpose of this study was to determine whether fashion and digital technology could be combined to create works and to suggest ways to apply digital technology in the fashion industry. As a research method, image generative AI, Midjourney was applied to the initial design ideation stage to derive inspiration images. 3D printing technique was then introduced as a production method to print fashion jewelry. As a result of the research, a total of six jewelry designs printed with a 3D printer were developed. One necklace, one bracelet, three earrings, and one ring were developed. This study identified the possibility of applying digital technology to real fashion jewelry design products by designing jewelry based on inspirational images derived from image generation AI and producing pieces of fashion jewelry with 3D modeling tasks and 3D printing outputs. This study is significant in that it expands the expression area of fashion jewelry design that combines digital technology.

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.

3D printing technology is a key technology of the Fourth Industrial Revolution and has been gaining attention in various fields, having been selected as one of the top 10 core manufacturing technologies by the U.S. government. In the apparel industry as well, there have been various attempts to develop products using 3D printers. However, compared to other industries and research fields, utilization remains insufficient. This is mainly due to the high price of large 3D printers and a limited varieties of filaments, making it difficult to implement traditional textiles and produce full-size garments. In this study, to develop 3D printed textiles, textile structures that can be 3D printed were categorized. Applying various types of filaments and layering methods allowed for the printing and evaluation of structures, ultimately leading to the selection of three types of 3D printed textile structures suitable for use as clothing materials. Subsequently, types of filaments were selected that match the chosen textile structures and suitabel designs were applied to develop 3D printed clothing designs. As a result of this study, an ideal form for 3D printing textiles was proposed and mehods were presented for clothing construction using practical (versatile) 3D printing technology. This study plays a significant role in contributing to the expansion of research areas related to 3D printing technology in the fashion field and suggesting effective research directions.

This study was to develop a dress form that is highly representative of the body shapes of senior men in their 50s and 60s. And this research was compared the measurements and forms of three different dress forms available in the market, in order to analyze the body type and suitability and provide a standard for developing and utilizing the dress forms. After extracting the body shapes of the senior men's 3D shape, the body type that is curvature on the back prevalent among senior men, was chosen. The dress form was created as follows: 3D modeling and rendering, printing with a FDM-type 3D printer. The dress forms were 3D-scanned and the 3D data was analyzed - classification drop value, area deviation, compared horizontal section and vertical section. The results were as follows: This suggested that the area deviation amount at the chest and hip circumference levels was larger in the commercial products than in the dress form in this study, while that at the waist circumference level was larger in the dress form in this study. The vertical length of the lateral shoulder point-waist circumference was smaller, the side shape showed severe curvature on the back, and the waist circumference was larger in the senior men dress form than the commercial products. The dress form developed in this study reflected the body type of senior men and, therefore, were suitable for fitting when creating clothes for senior men.

직접인쇄기술 방식은 기존의 포토리소그래피 방법을 이용한 패터닝 기술에 비해 저비용, 간단한 공정 과정, 친환경성 등 여러 장점들로 인해 미세 회로 형성 분야의 그린 테크놀로지로 최근 각광받고 있다. 이러한 프린팅 기반의 전자기술을 상용화하기 위해서는 프린팅 방식으로 형성된 회로의 전기적 특성 평가가 필수적인데, 이에 본 연구에서는 구리 잉크를 이용하여 잉크젯 프린팅 방식으로 2 가지 타입, parallel transmission line(PTL)과 coplanar waveguide(CPW) 구조의 회로를 형성하고 $250^{\circ}C$에서 30분 동안 소결하여 완성하였다. 전류-전압 그래프로 직류 저항을 측정하여 벌크 구리의 비저항 값의 약 3.3배되는 평균 0.558 ${\mu}{\Omega}{\cdot}cm$의 비저항 값을 도출하였고 회로의 고주파 특성 평가를 위해 주파수 범위 0~30 GHz에서 probe station chuck과 샘플 간의 갭 유무에 따른 scattering parameter를 측정하였다. 모든 시편에서 5 dB 이하의 반사 특성을 보였으며, PTL 회로가 CPW 구조보다 전반적으로 더 좋은 통과 특성을 나타내었다.
