Introduction 1.1 Background of Project In recent years, coalesced deposition clay sculpture (FDM) has become a widely utilize technology in rapid prototyping process. Typically polymer materials used are acrylonitrile barelyadiene phenylethylene (ABS) and polycarbonate (PC). The polymer is fed into equipment as a 1.6mm diameter, which is heated and extruded onto a twist platform. The ABS filament sold by the equipment suppliers is very expensive at around?270 per kg [1]. Also, during the FDM process, somewhat of this material is used as build supports and which is simply throw away after organism removed from the parts. This throw polish off aims to use alternating(a) materials for the FDM process. 1.2 Previous achievement of Project This date is followed by a summer 2009 project that Yifei Zhang did. In Zhangs project, one signifier of virgin ABS has similar merge and flow properties to the benchmark material, only due to the limitations of laboratory equipment and project funds, Zhang cannot fill the result. Zhang also punish to use WEEE ABS as a potential source, but the tier of purity (98%) could not be accepted in FDM operation. In addition, a nylon strimmer line was install which had the suitable filament diameter, but it also failed because of the viscosity of the materials. 1.

3 Objectives of Project later on summarize the Zhangs experience, the target of project is to identify the cheap alternate(a) polymeric materials to ABS. Before the project, a further polymer understanding of the leave and flow properties should be reviewed. Some problems Zhang met need to be jab to success replete(p)y produce the product. Some exper! iments, which Zhang did, need to be take over to have a better understanding of this project. Some movement materials are aimed to produce the products, and then the properties of product are evaluated. 2. literary works Survey 2.1 Why use rapid prototyping methods? speedy Prototyping (RP) is defined as the use of a computer assisted design (CAD)-based alter additive manufacturing process to...If you want to get a full essay, order it on our website:
