Raytheon research points to 3-D printing for tomorrow's technology
http://www.raytheon.com/news/feature/3d_printing.html“Researchers at Raytheon Missile Systems say they have already created nearly every component of a guided weapon using additive manufacturing, more commonly known as 3-D printing. The components include rocket engines, fins, parts for the guidance and control systems, and more.”
Компоненты ракеты с использование 3Д печати уже делаются для двигателя, крыльев, для контроля движения.
“ Engineers are exploring the use of 3-D printing to lay down conductive materials for electrical circuits, create housings for the company's revolutionary gallium nitride transmitters, and fabricate fins for guided artillery shells.”
Инженеры открывают использование 3Д печати для проводиков в электр.цепях, оболочку для GaNi передатчиков и крыльев для управляемых снарядов.
“The process may reduce costs associated with traditional manufacturing, such as machining of parts. It allows for quick design and rapid changes because engineers only need change the digital model representing the part. As long as they stay within set parameters, they can have new parts in hours instead of weeks.”
Процесс снижает стоимость по сравнению с обычным произ-вом, быстрый дизайн и быстрое изменение позволяет получить новый образец за часы, а не недели.
““You can design internal features that might be impossible to machine,” said Raytheon engineer Travis Mayberry, who is researching future uses of additive manufacturing and 3-D printing. “We’re trying new designs for thermal improvements and lightweight structures, things we couldn’t achieve with any other manufacturing method.”
Мы можем создать ранее не создаваемое - термически улучшенные и легковесные структуры, которые невозможно получить в обычным способом.
Ниже описывается как они печатают микросхемы - мне лень переводить, sorry..
“The current method of building microscopic circuits involves removing material to create a circuit pathway. In contrast, 3-D printing lays down just the material needed to build the electronic pathway.
“The word ‘printing’ implies lower cost,” said Chris McCarroll, Raytheon director for the institute. “It’s additive manufacturing. When we make integrated circuits [now], it’s all subtractive. We put down very expensive materials and wash away everything we don’t need.”
Circuits can already be printed with inkjet printers. The goal is to print more complicated circuits in three dimensions, with the very high resolution and performance of silicon, he said.”
“Yet as clear as the challenges are, so is the promise. “There are folks in industry printing warheads,” said Danforth. “We are printing demos of many of the seeker components. And we demonstrated a printed rocket motor. We’ve already printed 80 percent of what would go into a missile.”
Это трудно, но многообещающая технология. Некоторые пацаны в этой области уже печатают боеголовку, а мы уже печатаем 80% того что в ракете, и двигатель полностью напечатан.
О проблемах с комплектующими в статье не было.
