1990년대 후반 3D Printer를 활용한 CAD/CAM 시스템의 도입은 주얼리 산업에 많은 변화를 가져오게 되었다. 2009년 FDM방식의 특허 만료를 시작으로 주요 특허가 풀리면서 저가의 3D Printer가 주얼리 산업에 보급되었다. 주얼리 대량생산프로세스는 3D Printer가 생산라인의 한 부분을 차지하는 직접제조 프로세스로 변화할 것이다. 이러한 변화에 본 연구는 3D Printer를 활용한 주얼리 제조 프로세스를 제시하고, 다른 색상의 이종금속이 접합된 주얼리 시제품을 제작하였다. 이를 통하여 3D printer의 활용범위를 높이고, 주얼리 대량생산 방법의 다양성을 제시하였다.

Thermal flows inside a laser printer are affected by generated heat from a fuser and boards. Thus, the effect of fans has been investigated to control the thermal flows and behaviors of toners. In order to analyze the phenomena experimentally, a PIV (Particle Image Velocimetry) has been used, and then the flow inside the printer has been predicted by the CFD (Computational Fluid Dynamics) in this study to determine the efficient flow distribution by an optimum design of the printer. The determined optimum design has been confirmed by the developed PIV technique so that the efficiency of the laser printer can be improved by the proposed design.

3D printing is a technology that converts a computer-generated 3D model into a real object with additive manufacturing technology. A majority of 3D printing technologies uses one material, and this is considered a limitation. In this study, we developed a multi-material 3D printer by adopting dual resin vat and cleaning system with DLP (Digital Light Processing) 3D printing technology. The developed multi-material DLP 3D printer is composed of a manufacturing system, cleaning system, transporting system, and automatic resin recharging system. Various 3D structures were 3D printed with two materials, thus demonstrating the potential. Printing performance of the multi-material DLP 3D printer was studied by performing a comparative surface roughness test and tension test on specimens composed of one material as well as those composed of two materials.

This paper describes design techniques of general purpose thermal array printer, especially easily applicable to medical measurement equipment. The'general'means that the proposed thermal array printer can be applied to not only medical field but other industrial field by establishing the eligible protocol. The thermal array printer is composed of i)MPU and its peripherals ii)printer head control, iii)diverse protection circuits, and iv)serial communication. In this paper the performance of the proposed thermal array printer was evaluated by applying to an 3 channel electrocardiogram recorder. The propped system can support'Hangul'text as well as alphanumeric characters and any bitmap image.

This paper presents the development of a 3D printer based piezo-driven vertical micro-positioning stage. The stage consists of two flexure bridge structures which amplify and transfer the horizontal motion of the piezo-element into vertical motion of the end-effector. The stage is fabricated with ABS material using a precision 3D printer. This enables a one-body design eliminating the need for assembly, and significantly increases the freedom in design while shortening fabrication time. The design of the stage was optimized using response surface analysis method. Experimental results are presented which demonstrate 100nm stepping in the vertical out-of-plane direction. The results demonstrate the future possibilities of applying 3D printers and ABS material in fabricating linear driven motion stages.

3D 프린터의 빠른 보급에도 불구하고 3D 프린팅 속도 느리기 때문에 3D 프린터를 여러 사람이 동시에 이용하기에는 어렵다. 기존 3D 프린팅 솔루션은 SD 카드에 파일을 옮겨서 출력하거나 PC에서 출력하는 방법이 있으나 시간이 많이 소요되고 프린팅 진행정도를 알 수 없다. 아직 원격에서 3D 프린터를 제어하고 프린팅이 가능한 솔루션은 없다. 따라서 본 3D 소프트웨어 솔루션은 인터넷 네트워크 상에 3D 프린터를 연결하고 이들 프린터를 이용하기 위해서는 스마트폰 앱에서 사용할 프린터를 선택하며 원격 제어 및 프린팅이 가능하도록 한다. 본 논문에서는 이러한 기능들이 수행 가능한 안드로이드 앱을 제작하기 위하여 UML을 이용한 효과적인 분석/설계 및 구현 방법을 제시하고자 한다.

Many practitioners in educational field, recently, are seeking to improve Computational Thinking through SW education. The purpose of this paper was, for promotion of SW education, to design the STEAM education process utilizing 3D printer. The project-based education process emphasized the cooperation in the process of producing common results and proposed a new STEAM education process. The designed products are expected to be used in the elementary school classes by linking with the camp and teacher training programs and the curriculum.

산업혁명의 발전으로 소품종 대량생산에서 다품종 소량 생산의 형태로 제조의 패러다임이 변화하고 있음을 확인할 수 있는데, 이는 생산자의 무분별한 제고의 부담을 줄일 수 있는 형태로 현대 사회가 발전할수록 바뀌어야 하는 생산성 부분의 문제점을 보완하려는 산업형태의 변화를 보여주고 있다. 3D Printing 환경에서 살펴보면 프린팅의 마지막 단계까지 도달하는 과정에서 많은 문제가 발생한다. 이 문제는 저가의 보급형 3D Pirnter 만이 아니라 완제품으로 출시되는 고가의 3D Printer 또한 같은 증상들이 나타나고 있으며 프린팅을 하는 과정에서 불안요소를 발생시킬 수 있다. 그래서 이와 같은 문제점을 보완하고자 본 연구에서는 3D Printer의 안전성 및 제품 출력물에 대한 품질 관리 시스템에 대한 제안을 연구에 기초하여 3D Printer 개인 사용자를 타겟으로 하는 IoT 비콘 기반 3D Printer 원격 안전·품질 관리 시스템 설계를 제안한다.

In recent years the industry has utilized some of the 3D printers in the manufacturing process a trend which spread also a personal desktop 3D printer priced. The 3D printer can create the 3D object by using an ink or a laser instead of the powders, and various liquid plastic material. Properties of 3D printers are liquid, solid, powder and raw materials are also classified as varied. New ideas and processes in the form of designer furniture, becoming increasingly evolved through the development of materials and technologies. Science, art and technology combine to create a new aesthetic for the complex and free binding structure is a combination of design and materials are available in craft and the structure appears not showing. 3D scanning was not simply continue to develop as the production process by a variety of tools and content transformation. Create new mathematical tables and chairs designed by the theory fit the digital age shows a coupling structure with decoration into small pieces. It has created a new craft technique in the digital age.
