fused deposition modeling (fdm) is a filament based rapid prototyping system provides us to manufacture real parts with multiple production-grade materials, such as abs-m30, pc, ppsf and pc-abs blend. fused deposition modeling technology, essentially perform using layer manufacturing process. more complex 3d physical models can be efficiently fabricated without geometric limitation by this tech...

There is a world-wide demand for clean, reliable and affordable energy. New technologies are needed to produce more oil and natural gas from ‘stranded’ locations. This work is based on gas to liquid (GTL) conversion of natural gas through Fischer-Tropsch (FT) synthesis. Fe & Co based catalysts of varying compositions were prepared in the laboratory and its performance was checked for the FT rea...

Many Indian ammonia plants struggle with high feedstock prices. In order to survive in the competition from new plants in areas with low gas cost, many plant owners of existing plants have decided to revamp their plants to reduce the energy consumption and/or increase the capacity. New developments are needed in order to fulfil these needs of the market. This paper will highlight some of the de...

A key aspect of MMIC technology development and production is reliability. At Northrop Grumman Space Technology (NGST), reliability assessment and improvement are incorporated into the formative stages of technology development and continue through process qualification and manufacturing. Key components of this approach include: multi-temperature accelerated life testing; other accelerated life...
