Abstract: Rapid prototyping technology have emerged a new innovation to reduced the time cost of moulds fabrication by creating 3D product directly from computer aided design thus the designer is able to perform design validation and accuracy analysis easily in a virtual environment as if using a physical model. The primary aim of this paper is to give the reader an overview of the current state of the art in rapid prototyping technology .The paper also deal with feature’s of rapid prototyping in Aerospace industry and some of the existing problem’s of rapid rototyping.

Abstract: review of the literature from 1991 to 2002 on the use of rapid prototyping in the biomedical area emphasizes the applicability of this technique to aid diagnosis and planning in maxillofacial surgery and traumatology. a case report in which a tmj ankylosis relapse was treated using rapid prototyping (selective laser sintering) for surgery planning is presented. after one year, the patient's buccal opening was 45 mm. transitory paralysis of the facial nerve disappeared totally in six months.
Rapid prototyping for sling design optimization  [PDF]

Computer Science , 2014,
Abstract: This paper deals with combination of two modern engineering methods in order to optimise the shape of a representative casting product. The product being analysed is a sling, which is used to attach pulling rope in timber transportation. The first step was 3D modelling and static stress/strain analysis using CAD/CAE software NX4. The slinger shape optimization was performed using Traction method, by means of software Optishape-TS. To define constraints for shape optimization, FEA software FEMAP was used. The mould pattern with optimized 3D shape was then prepared using Fused Deposition Modelling (FDM) Rapid prototyping method. The sling mass decreased by 20%, while signifficantly better stress distribution was achieved, with maximum stress 3.5 times less than initial value. The future researches should use 3D scanning technology in order to provide more accurate 3D model of initial part. Results of this research can be used by toolmakers in order to engage FEA/RP technology to design and manufacture lighter products with acceptable stress distribution.

Abstract: This research has done to find out the present communicative qualification of parents with students.Through the research, parents of primary school V. grade students were chosen for sampling. Data have been collected with‘the scale of instructional communicative qualification of parents’ that its reliability and validity study have done anddeveloped by the researcher. According to this, there are 34 items at the instructional communicative qualification of parentswith students. Descriptive statistics, t-test and one-way-ANOVA are used through the data analyses. Through the researchcommunicative qualification of parents with students was compared with the nominal variables (age, education andprofession). It was found out that parents find themselves sufficient through the communication with students (with theirchildren).

Abstract: virtual reality (vr) provides another dimension to many engineering applications. its immersive and interactive nature allows an intuitive approach to study both cognitive activities and performance evaluation. market competitiveness means having products meet form, fit and function quickly. rapid prototyping and manufacturing (rp&m) technologies are increasingly being applied to produce functional prototypes and the direct manufacturing of small components. despite its flexibility, these systems have common drawbacks such as slow build rates, a limited number of build axes (typically one) and the need for post processing. this paper presents a virtual assembly rapid prototyping (varp) project which involves evaluating cognitive activities in assembly tasks based on the adoption of immersive virtual reality along with a novel non-layered rapid prototyping for near net shape (nns) manufacturing of components. it is envisaged that this integrated project will facilitate a better understanding of design for manufacture and assembly by utilising equivalent scale digital and physical prototyping in one rapid prototyping system. the state of the art of the varp project is also presented in this paper.
Paper Prototyping as a Rapid Participatory Design Technique  [cached]

Computer and Information Science , 2009, DOI: 10.5539/cis.v2n3p53
Abstract: This paper describes participatory activities with university lecturers to design an online community. The objective of this study is to engage the users of an online community to collaboratively design their online community. We speculated that by involving them in the design team, we can identify their specific requirements, and they will accept and use the system. However, lecturers have heavy workload and tight schedule. For that reason, we thought that paper prototyping is the most suitable tool to be used because it is fast and easy to create. Therefore, paper prototyping technique has been adapted in a two-day participatory design session. We found that paper prototyping is indeed the most suitable technique to elicit requirements from the end users under a time constraint. Moreover, participants came out with unexpected requirements and novel interface.
A Rapid Prototyping Environment for Wireless Communication Embedded Systems  [cached]

EURASIP Journal on Advances in Signal Processing , 2003, DOI: 10.1155/s168761720330304x
Abstract: This paper introduces a rapid prototyping methodology which overcomes important barriers in the design and implementation of digital signal processing (DSP) algorithms and systems on embedded hardware platforms, such as cellular phones. This paper describes rapid prototyping in terms of a simulation/prototype bridge and in terms of appropriate language design. The simulation/prototype bridge combines the strengths of simulation and of prototyping, allowing the designer to develop and evaluate next-generation communications systems, partly in simulation on a host computer and partly as a prototype on embedded hardware. Appropriate language design allows designers to express a communications system as a block diagram, in which each block represents an algorithm specified by a set of equations. Software tools developed for this paper implement both concepts, and have been successfully used in the development of a next-generation code division multiple access (CDMA) cellular wireless communications system.

Abstract: The paper presents an analysis incremental methods of creating wax founding models. There are two methods of Rapid Prototypingof wax models in an incremental process which are more and more often used in industrial practice and in scientific research.Applying Rapid Prototyping methods in the process of making casts allows for acceleration of work on preparing prototypes. It isespecially important in case of element having complicated shapes. The time of making a wax model depending on the size and the appliedRP method may vary from several to a few dozen hours.
Critical Parameters Effecting the Rapid Prototyping Surface Finish
Journal of Mechanical Engineering and Automation , 2011, DOI: 10.5923/j.jmea.20110101.03
Abstract: A component can be manufactured in several ways. Rapid Prototyping technique is one among the material adding manufacturing process, building up its unique potential in the present scenario. This technique helps manufacture a product from the basic design of the component, thus optimizing the iterative product development process time and creating geometrically complex parts to precise dimensions. In the Rapid Prototyping process, surface finish is critical as it can affect the part accuracy, reduce the post-processing costs and improve the functionality of the parts. This paper presents an experimental design technique for determining the optimal surface finish of a part built by varying Build Orientation, Layer Thickness and keeping other parameters constant using the Fused Deposition Modeling (FDM) process. The design investigates the effect of these parameters on the surface finish. Experiments were conducted using a fractional factorial design with two levels for Layer Thickness and three levels for Build Orientation factor. The results are statistically analyzed to determine the significant factors and their interactions. The significant factors, their interactions and the optimum settings are proposed.
