Comparative LCA of conventional manufacturing vs. additive manufacturing: the case of injection moulding for recycled polymers
نویسندگان
چکیده
Additive Manufacturing helps to develop production alternatives with new technologies and less environmental impacts. The comparative analysis was performed between two manufacturing processes using black recycled Acrylonitrile Butadiene Styrene (ABS) pellets evaluate the potential impacts Injection moulding Fused Deposition Modelling (FDM). Life Cycle Assessment (LCA) Unit Process Inventory (UPLCI) methodology were adopted, which resulted in an impact assessment separated by operation modes subunits of equipment. LCA results indicate a lower FDM when aim is produce batch size smaller than 14 parts. For sizes above 50 parts, process generated Global Warming Potential (GWP) Cumulative Energy Demand (CED). printing stage contributed most generating for FDM. In process, main responsible injection phase. Mechanical tensile tests carried out parts obtained different infills (25%, 50%, 75% 100%), it observed that 100% infill best relation mechanical properties

Application of Additive Manufacturing in Marine Industry
The advantage of additive manufacturing (AM) (e.g. reasonable time and expense in prototyping, and reliable product) has triggered the idea of using this method in manufacturing of marine vessels components. The current article tries to introduce basic concepts of AM method and its application in marine industry; have a glance at additive-manufactured parts microstructure; elaborate the challen...
متن کاملPolymers for 3D Printing and Customized Additive Manufacturing
Additive manufacturing (AM) alias 3D printing translates computer-aided design (CAD) virtual 3D models into physical objects. By digital slicing of CAD, 3D scan, or tomography data, AM builds objects layer by layer without the need for molds or machining. AM enables decentralized fabrication of customized objects on demand by exploiting digital information storage and retrieval via the Internet...

هدف اصلی نرخ گذاری بیمه ای تعیین نرخ عادلانه و منطقی از دیدگاه بیمه گر و بیمه گذار است. تعین نرخ یکی از مهم ترین مسایلی است که شرکتهای بیمه با آن روبرو هستند، زیرا تعیین نرخ اصلی ترین عامل در رقابت بین شرکتها است. برای تعیین حق بیمه ابتدا می باید مقدار مورد انتظار ادعای خسارت برای هر قرارداد بیمه را برآورد کرد. روش عمومی مدل سازی خسارتهای عملیاتی در نظر گرفتن تواتر و شدت خسارتها می باشد. اگر شر...
