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.

In any automobile the power is transmitted from one shaft to another by using chain drive. Chain drive consists of chain, driving sprocket and driven sprocket. The driving sprocket is connected to engine output shaft, which transfer power to driven sprocket by chain. Further this driven sprocket transfer power to drive shaft. The design and material selection of this chain drive plays a vital role in efficient running of the automobile. Present the material used for chain drive is mild steel. This paper involves increases the strength of the Pulsar 180cc chain drive by selecting the different materials (AISI 1050 steel, EN 8 steel, EN 32 steel, EN 19 steel and C45 steel). In this the Pulsar 180cc chain drive designed through reverse engineering approach and detailed finite element analysis is carried out to calculate stresses and deflections on the chain drive. Later the analysis is extended to fatigue analysis to estimate the life of the chain drive and the dynamic analysis is carried out to calculate stresses and deflections on the chain drive when it is in motion. SOLID WORKS software is used for doing 3D model of chain drive and ANSYS is used for doing finite element analysis.

Chassis frame is the skeleton of an automobile industry. It must be hard to resist the adequate shock, twist, vibration and bending stress occurred in operating condition. The material selection and design of chassis frame plays vital role in automobile industry. The chassis can resist the total load acting on the system and it holds the entire body of an automobile. So, highest stress, most equilateral stress and deflection are considerable factors while design of the chassis. In this Paper stainless steel, epoxy and aluminum are the different material used for chassis frame and it is modeled using solid works software and the Finite element analysis has been carried out with using ANSYS. The chassis frame has been optimized based on the most shear stress, equivalent stress and deflection and also responsiveness inspection is carry through to minimize the weight.

Service Inspection

In-service inspection and maintenance assessment of plant and equipment to reduce the risk of failure and hazardous release have been used for many decades as cost-effective procedures in concert with design, material selection, defect criteria, fabrication, and operation/use. Codes and standards have, more recently, sought to provide hazardous release protection as an additional means of reducing risk by means of criteria based on risk (event probability and consequences), including maintenance and inspection. These criteria use risk-based methods for prioritizing inspection and maintenance. In a power station or refinery, for example, the risk of unplanned shut-down is related to the failure or malfunction of a relatively small number of items. Risk-based maintenance and inspection allows efforts to be concentrated on items involving the highest risk, with a proportionate reduction in effort for low-risk items. Hence, base-load operating times can generally be increased, while maintaining the same or reduced level of risk. Maintenance and inspection play a vital role to reduce risk by more accurately quantifying event probability. Where there is a possibility of high-risk catastrophic failure, the consequences and risk to personnel, environment and equipment can be rendered tolerable to negligible if appropriate protective systems are in place with reduced maintenance and inspection. This paper reviews several cases in which the authors have been involved and in which failures would have been prevented if proper risk assessment procedures had been in place or in which assessment of risk was made to prevent failure.

3D printing of drugs is an innovative and cost-effective technology, which is a major step towards personalized medicine. This technology can be used for the development of controlled-release drugs; fixed-dose combination drugs, as well as for the creation of orodispersible dosage forms. The global 3D drug market is still largely at the research stage, but its rapid growth is expected in the coming decade [1].

The choice of materials is crucial in responding to the increasing embodied carbon (EC) impacts of buildings. Building professionals involved in material selection for construction projects have a vital role to play in this regard. This paper aimed to explore the extent to which building professionals in Sri Lanka considered EC as a material selection criterion. A questionnaire survey was conducted among a sample of building professionals in Sri Lanka. The results indicated that the consideration of EC as a material selection criterion remained low among key professionals, such as architects, engineers, and sustainability managers, despite their reasonable influencing powers and knowledge of EC. Those respondents who had considered EC as a selection criterion said they had been primarily driven by green building rating systems and previous experience. Those respondents who had not considered EC during material selection commonly reported that they had been prevented from doing so by the lack of regulations and the lack of alternative low carbon materials. Respondents believed that the involvement of actors, such as the government, professional bodies, environmental organizations, activist groups, and the public, may be significant in promoting the greater consideration of EC during material selection.

Combined Sewer

The Austrian standard for designing combined sewer overflow (CSO) detention basins introduces the efficiency of the combined sewer overflows as an indicator for CSO pollution. Additionally criteria for the ambient water quality are defined, which comprehend six kinds of impacts. In this paper, the Austrian legal requirements are described and discussed by means of hydrological modelling. This is exemplified with the case study Innsbruck (Austria) including a description for model building and model calibration. Furthermore an example is shown in order to demonstrate how – in this case – the overall system performance could be improved by implementing a cost-effective rearrangement of the storage tanks already available at the inflow of the wastewater treatment plant. However, this guideline also allows more innovative methods for reducing CSO emissions as measures for better usage of storage volume or de-centralised treatment of stormwater runoff because it is based on a sewer system simulation.
