ABSTRACTRecently Lightwave Device Packaging Department at AT&T Bell Laboratories has demonstrated that ceramic materials can provide cost effective and high quality packages to house optical and electronic components for lightwave communication applications. In this paper we examine the material requirements for optical packages. We also study the material properties of metals and ceramics with a potential application in optical packages. In particular, we review hermeticity, thermal conductivity, thermal expansion coefficient, dielectric constant, electrical resistivity, sintering temperature and mechanical strength of these materials. Our study will provide a data base and useful guidelines for designers to make uniformed decisions on material selection for optical package. We also review the mixing rules to predict the resultant property of a composite from the known attributes of its constituents and the use of new composite materials will provide a new degree of flexibility in the optical package design.

Development of prototypes draws major focus in contemporary manufacturing organisations. Sustainability analysis and comparison of the prototype manufacturing process plays a vital role in deciding the sustainability level of the product. Sustainability of prototyping depends on model building material and model building process. In this paper based on the customer requirements, Environmental Conscious Quality Function Deployment (ECQFD) was carried out. Increased lives, strength, reduced toxicity of material with biodegradability were the major outputs of ECQFD. Cambridge Engineering Selector (CES) and Grey Relation Analysis (GRA) were used for material selection. Wood, ABS, Poly Lactic acid (PLA) and Lead were selected as cost efficient materials for the case product. A CAD model of the case product was developed and subjected to Life Cycle Analysis (LCA) using solid works sustainability express for the above materials. Prototypes of the case products where produced by wood carving, casting, CNC Milling and 3D printing by considering all input parameters required across each process. LCA was conducted using GaBi for the above process and the results were compared. From this study, it was observed that the case product developed using PLA with 3D printing technology had very less impact on environment and is considered as the best and cost effective prototyping method.

Abstract This paper describes a method for evaluating the compatibility of a product design with respect to end-of-life product retirement issues, particularly recyclability. Designers can affect the ease of recycling in two major areas: 1) ease of disassembly, and 2) material selection for compatibility with recycling methods. The proposed method, called “clumping,” involves specification of the level of disassembly and the compatibility analysis of each remaining clump with the design’s post-life intent; i.e., reuse, remanufacturing, recycling, or disposal. The method uses qualitative knowledge to assign a normalized measure of compatibility to each clump. An empirical cost function maps the measure to an estimated cost to reprocess the product. The method is an integral part of our life-cycle design computer tool that effectively guides engineers to an environmentally responsible product design. A refrigerator in-door ice dispenser serves as an illustrative example.
