NASA, Industry Test "3D Printed" Rocket Engine Injector

NASA, Industry Test "3D Printed" Rocket Engine Injector | History 2[+or less 3].0 | Scoop.it

NASA and Aerojet Rocketdyne recently finished testing a rocket engine injector made through additive manufacturing, or 3-D printing.
The series of tests demonstrated the ability to design, manufacture and test a critical rocket engine component using selective laser melting manufacturing technology -- a method that employs high-powered laser beams to melt and fuse fine metallic powders into three dimensional structures.
This type of injector manufactured with traditional processes would take more than a year to make, but with these new processes it can be produced in less than four months, with a 70 percent reduction in cost.

If 3d printing is good enough for NASA shouldn't we all be thinking about it...

HG Académie de Rennes's curator insight, April 17, 2014 4:00 PM

Ressource numérique interactive mêlant planisphère, routes maritimes, graphiques de l'activité portuaire et vues aériennes des plus grands ports du monde et de leur aménagement notamment pour la conteneurisation du commerce maritime. Une ressource tout à fait exploitable en 4e bien qu'étant en anglais (très peu de texte). On pensera aussi à la classe de terminale et aux DNL anglais.

Un excellent site très utile lorsque l'on traite de la mondialisation

Samuel D'Amore's curator insight, December 17, 2014 5:05 PM

While this might simply seem like a group of ports the more important message conveyed is that in fact that the majority of them are located in East Asia. Gone are the days of the industrial centers of the earth being located in Europe and the Americas. Paired with cheap labor and ease of global transportation many of these East Asian countries are quickly over coming many of the earths previous economic giants.
