Purpose This paper provides an overview of the different binding mechanisms in selective laser sintering (SLS) and selective laser melting (SLM), thus improving the understanding of these processes. Design/methodology/approach A classification of SLS/SLM processes was developed, based on the binding mechanism occurring in the process, in contrast with traditional classifications Energy and material efficiency of steel powder metallurgy
- IntroductionAn Analysis of The Steel Powder Metallurgy Production ChainMaterial and Energy owsOpportunities to Reduce GHG Emissions in PMAcknowledgmentsReferencesPowder metallurgy processes provide opportunities that are not available when using material in the conventional form:Melting is not required in order to form complex components, and the rapid solidication typical of powder production allows for use of highly alloyed compositions. Concern about global warming has led to agreement on national and international targets to reduce greenhouse gas (GHG) emissions . Industry is responsible for 35 percent of all energy/process emissions [2, p. 13]. EmiProcess selection charts based on economy and environment Aug 03, 2020 · Results show that selective laser melting is the best trade-off in the mindset of neutrals and environmentalists, while machining is preferred by economists. Moreover, the proposed methodology can be used in situations where costs and environmental impacts are defined as ranges rather than determined numerical values.
For example, Kellens studied the environmental impact modeling in selective laser sintering processes laying an important basis of helping to identify and quantify measures for significant impact Experimental Assessment of a 3D-Printed Stainless Steel Jun 05, 2020 · Additive manufacturing (AM) is a disruptive technology in prototyping and fabrication. This paper accesses the feasibility of AM in the fabrication of GFBs using selective laser melting (SLM) technology. A stainless steel GFB is 3D-printed in one piece, including the Life cycle assessment of selective-laser-melting-produced Dec 01, 2020 · Selective laser melting (SLM), a relatively advanced additive manufacturing (AM) technique, enables high design flexibility and manufacturing complexity; therefore, it can facilitate improvement in the environmental performance of a complex component throughout its life cycle.
Environmental assessment of Selective Laser Melting compared with Laser Cutting of 316L stainless steel:A case study for flat washers production In industrial practise, decision makers should know performance characteristics, cost- and energy-related impacts for choosing the most suitable manufacturing technology for a specific product. Simone Venettacci Università degli studi Niccolò Cusano Environmental assessment of Selective Laser Melting compared with Laser Cutting of 316L stainless steel: The aim of the study is to show how the chosen pump component can be effectively re-engineered and produced with the selective laser melting technique, obtaining a final product that is comparable if not even better than the starting one The Environmental Impacts of Metal Powder Bed Additive Additive manufacturing (AM) is widely recognized as a critical pillar of advanced manufacturing and is moving from the design shop to the factory floor. As AM processes become more popular, it is paramount that engineers and policymakers understand and then reduce their environmental impacts. This article structures the current work on the environmental impacts of metal powder bed processes:selective laser melting (SLM), direct metal laser sintering (DMLS), electron beam melting
