  • Rapid prototyping technology has been widely applied to the design process in the industry. This technology made it easy to generate a prototype which acts like a real product in logic. However, this technology has not been validated sufficiently as a usability test method. The purpose of this study was to test the hypothesis : There was no significant difference between a real product and its prototype. An experiment was designed to test it statistically. a microwave oven was selected and its prototype was generated using a rapid prototyping tool. Six subjects used the microwave oven and another six subjects used the prototype to perform five scenario tasks. As a result, there was significant difference between the real product and prototype in success rate, task completion time, and number of buttons pressed. The prototype was more difficult to operate than the real product. Therefore we should be careful when we apply rapid prototyping. technology. In the discussions, the causes of the difference were identified and some guidelines were suggested for who wants to apply rapid prototyping tool to the usability test.

  • This paper presents studies on the creation time of scanning path using rapid prototype device. In the case of Jewellery, it needs to take time too much at the whole process of rapid prototype in accordance with heigh of the multi-layered. When increases the number of polygon by heigh of the Multi-layered, it has proper influence on the creation time of scanning path. Therefore, we can get the spending time and the number of polygon for the creation during increase the heigh of the multi-layered. These values are showed by the quantitative. We try to analyze relation between these and heigh of the multi-layered.

  • 자동차 man-machine system의 interface를 이루는 Display panel, Center fascia, Steering wheel, Rear view, Gear, Power window switch, Seat 등과 이들의 Layout은 운전자의 안전뿐만 아니라, 안락감과 밀접한 부분으로 알려져 있다. 따라서 이러한 설계요소들의 Man-machine interface의 최적화를 위한 인간공학적 접근이 필요하다. 운전자의 안락감은 Seat, Pedal, Steering wheel 등 뿐만 아니라 각종 조작장치(Audio, Switch, Gear,…)도 함께 연구되어야 하다. 따라서, 본 연구에서는 실험용 Seating buck을 제작하여 실내 조작장치 중 오디오를 대상으로 터치스크린과 Rapid Prototype을 이용해 사용성 평가에 대한 적합성을 검증하고자 하였다. Rapid Prototyping 기법은 디자인단계에서 제품 사용상의 문제점을 발견 개선할 수 있다는 장점이 있다. 그러나, 본 연구 결과에서 3가지 항목 중 1가지만이 실제 Audio와 Prototype에서 차이가 없었다. 따라서, Prototype의 접촉감과 입체감의 개선, 실사용과 동일한 환경의 제시, 소리와 같은 정확한 반응의 제시, Glare의 제거, 사용자 분석에 따른 실험 데이터의 축적 등을 고려하여 Rapid Prototyping을 구현하여야 할 것이다.

  • Rapid Prototyping(RP) models are no longer used only for design verification. Currently, parts built utilizing layer manufacturing technology can be employed as functional prototypes and as patterns or tools for different manufacturing processes such as vacuum casting, investment casting, injection molding, precise casting and sand casting. This trend of Rapid Prototyping application meets the requirement of concurrent engineering and its range covers a more spreaded area. The aim of this paper is saving the manufacturing lead time and cost of plastic parts having hollow space shapes used by prototype-car. Using rapid prototype patterns, made by the Selective Laser Sintering(SLS) technique, a new approach of manufacturing resin-based blow mold is discussed. It has a great potential fur making prototype-car parts with the batch size of under 200 parts, in case of rapid modification due to a subsequent design changes in developing stage. So, the process proposed in this research shows reduction of process time and manufacturing cost when compared with the conventional process such as a Zinc Alloy fur Stamping(ZAS) mold.

  • As a life cycle of product bas shortend, Rapid prototypiug has come into the spotlight to shortened the time of producint a prototype. But It followed in laminated directivity and of the prototype production which is decided the interference which Beccuase of invisible rough surface, some inferences have occured during an assembly hour. Consequently, This study on rapid prototyping has parameter to determine surface roughness and surface form precision of total shape. In order to improve Surface form precision, it can control parameters which are Laminate Height, Layer Hatch Overcue, Fill Cure Depth. In addition, we found the parameter which have a deep effect on surface roughness among various parameters, and then, tried to reduce the interference that can be occurred by surface roughness during assembly.

  • Recently, the variation of industry has been changed faster and faster than before. It is using Rapid Prototyping Method to cope with fast change. This technology used to make a prototype, master pattern of manufactured product by vacuum casting, and so on. But this method has errors by contraction as a necessity. this error has been caused because the shape of prototype is smaller than CAD data. So we must solve the problem about precision of product. Therefore in this study, we will reduce the errors like contraction of material by manufacturing of rapid prototype product. Through these courses, we will enhance a precision of product.

  • The business of manufacturing is increasingly becoming time-compressing, precise and long-life oriented, owing to various needs from the consumers and harsh global competition. With the emergence of the layer laminate manufacturing method, it is possible to produce prototypes directly from 3D CAD and additive process, the production time and cost have shortened dramatically. However there are some problems like surface-step, dimensional deviation and warp. A newly developed powder casting is suitable for rapid-manufacturing metallic tools. Powder casting can serve as a promising rapid tooling method because of high density characteristics and low dimensional shrinkage below 0.1% during sintering and infiltration. By this process, we have realized significant time savings bypassing the wait for prototype tooling and cost savings eliminating the expense of conventional prototype tooling process.
