Spreading knowledge about how SDRs are created and used is therefore of great social importance. Supports Technological Advancements in Additive Manufacturing … The use of conventional manufacturing methods is mainly limited by the size of the production run and the geometrical complexity of the component, and as a result we are occasionally forced to use processes and tools that increase the final cost of the element being produced. Design/methodology/approach • Design a unique, functional object that you would like to have – Pencil holder, chair, toy, lamp, etc… – Just a concept drawing or description © 2008-2021 ResearchGate GmbH. 3 Abstract This research project is a global study of the metal additive manufacturing from the optimization of the design phase to the improvement of the final state of the parts with finishing treatments and passing by the adjustment of the production process. In particular, by defining a set of Key Performance Indicators and applying a multi-criteria decision method, a final score is computed, giving important information about both environmental and economic aspects. Table 2: Current advantages of AM fabrication. (2004), "Compromise solution by MCDM methods: A com, Pham, D.T. They are however not entirely satisfactory, as they do not have the capabilities to reduce the influence of the deviation of performance parameter values on the decision-making result and to capture the risk attitudes of users in their decision-making models. Anyway, production volume strongly influences the economic results and the competitiveness of additive manufacturing remains limited when compared to the traditional manufacturing. With the rapid proliferation of desktop additive manufacturing units, a quantitative ranking system was developed to rate the units so a comparison can be made. the research and development of new product. Accordingly, more attention should be paid to the means and methods for making these decisions. In the next section, we will briefly explain, deal with constructing the individual and overall pref, . Each of these approaches can work well in its specific context. Robotics and Computer Integrated Manufacturing, Mintzberg, H., Raisinghani, D. and Theoret, A. The study. A better way of dealing with this situation needs to be fou. Selecting an appropriate additive manufacturing (AM) process or machine to fabricate an end-use product is an important issue in design for AM. Design/methodology/approach Most of the MCDM based approaches have an advantage in taking into account the relative importance of performance parameter types and a few of them also consider the interrelationships of performance parameter types. Additive Manufacturing “Factory” – Example 1 • Much smaller footprint that traditional factories • Separated into: • Office space • Printers • Post processing (furnace, powder recycling, grinding, machining) • Storage areas (powder, build plates, consumables, spare parts) • Generally each area is separated by a fire AM provides high practical relevance for B. The study applies structural equation modelling to understand whether individual investors, besides being rational, are subjected to self-attribution bias and overconfidence bias. Markforged produces the leading additive manufacturing platform for manufacturing and factory floors. Administrative/technical, environmental, social and economic aspects were elicited as critical factors for the development of sustainability criteria. Stanford University Press, Stanford, California. There is very limited information in there for users to fully understa, . According to BWM, the criteria to be selected by the decision maker based on the respondent expectations are identified. In the past years, the focus of many Additive Manufacturing users shifted to the pre and post processes of Additive Manufacturing after the first step of the ideal AM design. Thus, there is need to understand how AM can contribute to cover over which method achieves better UX in a certain context, i.e. SDRs are extremely important for government decision making. The software, machine time, materials and expertise required to make the most of the technology all come at a significant cost. It is aimed at proposing a quantitative model for the evaluation of different structure of supply chains based on different production technologies. numerous advantages of an additive process for component fabrication. Worked examples as well as the software featured in the book are available on an accompanying website. (201, Rosen, D.W. and Gibson, I. Comparison of methods and software is also featured to enable readers to choose the most appropriate method needed in their research. AM has experienced a rapid development in recent years. Machine and material costs are the significant parameters, which play a major role in cost estimation of the prototypes. Additive Manufacturing (AM) is an appropriate name to describe the technologies that build 3D objects by adding layer-upon-layer of material, whether the material is plastic, metal, concrete or one day…..human tissue.. Common to AM technologies is the use of a computer, 3D modeling software (Computer Aided Design or CAD), machine equipment and layering material. Additive manufacturing enables the building of three-dimensional, solid objects from digital … This book presents an introduction to MCDA followed by more detailed chapters about each of the leading methods used in this field. View Additive Manufacturing Research Papers on Academia.edu for free. Research limitations/implications Additive manufacturing is increasing in prevalence and importance across many industries. Design/methodology/approach This fabrication process, Social implications Purpose A large number of process alternatives are available both for the execution of the printing process and for the subsequent steps. The pros and cons, articulation of preferences approach. ... Laser baking printers are industrial equipment, as shown in [4, ... One reason is due to the characteristics of the raw material used in the additive process; different suppliers offer different raw materials in terms of properties even when the manufacturing process is the same. able to fully capture the user’s preferences. This might help investors to minimise the negative impact of self-attribution and overconfidence on their expected utility. Thus, the following article presents a decision support system for the design of the entire production process chain in the conceptual planning phase. parametric sometimes.
