Computer-aided design (CAD) and rapid prototyping (RP) are now a fundamental part of the professional practice of product design and are therefore essential skills for product design undergraduate students. This book provides students with all the tools needed to get to grips with the range of both CAD software and RP processes used in the industry.
RAPID prototyping, SELECTIVE laser sintering, DENTISTRY, and STEREOLITHOGRAPHY
The advent of Rapid prototyping has opened new prospects in medical field, especially dentistry with its accuracy and speed. Rapid prototyping is an additive manufacturing technology that produces prototype models by adding materials, layer by layer. The earlier subtractive technologies manufactured objects via milling or grinding of a material resulting in replication of only external surface details. On the contrary, rapid prototyping provides a replica with internal complex shapes. This article discusses the various Rapid prototyping technologies commonly employed in dentistry such as selective laser sintering, stereolithography, fused deposition modelling. inkjet printing and solid ground curing.

RAPID prototyping, REFUGEE camps, and DESIGN
More than 9 million people live in shelters globally, often in extremely hot climates. The thermal performance of shelters is often overlooked in the design process, despite being a consideration second only to safety in surveys of camp dwellers. Indeed, indoor temperatures exceeding 40°C have been recorded in previous studies. To aid in improving conditions, the roles building simulation and prototyping could play in forecasting shelter thermal performance as part of a new shelter design process are examined. The thermal performance of prototypes, built in the refugee camp of Azraq, was monitored during the hot season to evaluate four design approaches: (1) "blind" (uncalibrated) models, (2) calibrated models, (3) on-site design-variants and (4) off-site prototypes. These included the original shelter and six design alternatives implementing different overheating countermeasures. The results demonstrate that blind models are sensitive to the judgement of uncertainties but were still qualitatively useful. Model calibration vastly improves the agreement and significantly enhances forecasts of performance for the design alternatives, which remained similar across examined climates. It is therefore concluded that simulation and prototyping, either on-site or off-site, should be adopted within the shelter design process before mass deployment, to create better-living conditions for their dwellers.

"Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy is the summary of a workshop convened by the Air Force Studies Board of the National Academies' National Research Council in September 2013 to enhance Air Force and Department of Defense (DoD) prototyping for the new defense strategy. This workshop examined of a wide range of prototyping issues, including individual recommendations for a renewed prototype program, application of prototyping as a tool for technology/system development and sustainment (including annual funding), and positive and negative effects of a renewed program. Prototyping has historically been of great benefit to the Air Force and DoD in terms of risk reduction and concept demonstration prior to system development, advancing new technologies, workforce enhancement and skills continuity between major acquisitions, dissuasion of adversaries by demonstrating capabilities, maintaining technological surprise through classified technologies, and an overarching strategy of overall risk reduction during austere budget environments. Over the last two decades, however, many issues with prototyping have arisen. For example, the definitions and terminology associated with prototyping have been convoluted and budgets for prototyping have been used as offsets to remedy budget shortfalls. Additionally, prototyping has been done with no strategic intent or context, and both government and industry have misused prototyping as a key tool in the DoD and defense industrial base. Assessment to Enhance Air Force and Department of Defense Prototyping for the New Defense Strategy envisions a prototyping program that encourages innovation in new concepts and approaches and provides a means to assess and reduce risk before commitment to major new programs."--Publisher's description.
TRASTUZUMAB, DOCETAXEL, RAPID prototyping, IMMUNOGLOBULINS, NANOPARTICLES, and FLOW cytometry
Developing targeted nanoparticles is a rising strategy to improve drug delivery in oncology. Antibodies are the most commonly used targeting agents. However, determination of their optimal number at the surface remains a challenging issue, mainly due to the difficulties in measuring precisely surface coating levels when prototyping nanoparticles. We developed an original quantitative assay to measure the exact number of coated antibodies per nanoparticle. Using flow cytometry optimized for submicron particle analysis and beads covered with known amounts of human IgG-kappa mimicking various amounts of antibodies, this new method was tested as part of the prototyping of docetaxel liposomes coated with trastuzumab against Her2+ breast cancer. This quantification method allowed to discriminate various batches of immunoliposomes depending on their trastuzumab density on nanoparticle surface (i.e., 330 (Immunoliposome-1), 480 (Immunoliposome-2) and 690 (Immunoliposome-3), p = 0.004, One-way ANOVA). Here we showed that optimal number of grafted antibodies on nanoparticles should be finely tuned and highest density of targeting agent is not necessarily associated with highest efficacy. Overall, this new method should help to better prototype third generation nanoparticles. [ABSTRACT FROM AUTHOR]
VIRTUAL prototypes, VIRTUAL design, HUMAN-machine systems, MACHINERY, TASK performance, RAPID prototyping, and MOBILE robots
Limited visibility from a mobile machine cab can decrease task performance and lead to accidents. Therefore, it is important to consider visibility issues already in the design phase. This paper describes the use of virtual prototyping in the evaluation of see-through features of mobile work machines. The goal is to evaluate whether two different machine boom transparency levels have an effect on task performance. In addition, two alternative placements of overlaid information in the operators' field of view are assessed. A within-subject design was used in this study. Based on the results, there was no significant difference in performance between the transparency levels. However, the test participants preferred a transparency level of 70–80% (where 0% is completely opaque). Similar results were found with the placement of the overlaid information, which had no significant effect on task performance. Both placements, on the windscreen and on the tunnel wall, were equally favoured by the participants. The findings of this study contribute to the design of see-through features for mobile work machines. In addition, the study demonstrates the use of virtual prototyping in the design of novel features in human–machine systems. [ABSTRACT FROM AUTHOR]

"Additive Manufacturing Technologies: Rapid Prototyping to Direct Digital Manufacturing deals with various aspects of joining materials to form parts. Additive Manufacturing (AM) is an automated technique for direct conversion of 3D CAD data into physical objects using a variety of approaches. Manufacturers have been using these technologies in order to reduce development cycle times and get their products to the market quicker, more cost effectively, and with added value due to the incorporation of customizable features. Realizing the potential of AM applications, a large number of processes have been developed allowing the use of various materials ranging from plastics to metals for product development. Authors Ian Gibson, David W. Rosen and Brent Stucker explain these issues, as well as: Providing a comprehensive overview of AM technologies plus descriptions of support technologies like software systems and post-processing approaches ; Discussing the wide variety of new and emerging applications like micro-scale AM, medical applications, direct write electronics and Direct Digital Manufacturing of end-use components ; Introducing systematic solutions for process selection and design for AM.
