• NASA Successfully Tests First 3-D Printed Rocket Engine Injector

[quote]We've seen 3-D printed aircraft and drone parts, and even plans for a printable private jet. Now NASA has demonstrated another 3-D printing first: The agency has just finished successful tests of a 3-D printed rocket engine injector at the Glenn Research Center in Cleveland, Ohio, marking one of the first steps in using additive manufacturing for space travel. In conjunction with rocket manufacturer Aerojet Rocketdyne, NASA built the liquid-oxygen and gaseous-hydrogen rocket injector assembly using laser melting manufacturing. This sci-fi-sounding technique involves melting metallic powders down with high-powered laser beams, then fusing them into shape. Previous manufacturing methods for these type of injectors required more than a year. Being able to 3-D print the parts reduces the time frame to four months, at a 70 percent price reduction.

next up, the liberator 3d printed missile for muh freedoms
Reducing down production time by 8 months and saving 70% of the cost, I wonder if it sacrificed any quality.

[QUOTE=Tucan Sam;41433895]People are uneasy about 3D printers as it replaces more jobs.[/QUOTE] the same uneasiness the luddites felt.
[QUOTE=Tucan Sam;41433895]People are uneasy about 3D printers as it replaces more jobs.[/QUOTE] Eh. Not really. People still need to operate them and the parts were already machine made.
[QUOTE=Tucan Sam;41433895]People are uneasy about 3D printers as it replaces more jobs.[/QUOTE] Every fucking new machine that comes out, somebody goes "but muh jawbs!". Guess what, someone has to run/maintain those machines.
Imagine using a 3D printer onboard a ship to make replacements for damaged parts during a mission
Imagine a factory full of 3D printers that print other 3D printers and 3D printer parts. I, for one, welcome our 3D printer overlords.
Before you know it, the space shuttle will just print the parts that break.

The whole 3D printing factory printing 3d printers all ready exists, they are named "Farms" and plenty of small company have unto 30 printers printing new parts for new printers. Inception.
Well I have a 2D printer in my office and now theres 3D printers. Begs the question, when will 4D printers come around?
[QUOTE=Whiterfire;41447865]Well I have a 2D printer in my office and now theres 3D printers. Begs the question, when will 4D printers come around?[/QUOTE] They already have, you just don't know it because you don't have the right software to interpret 4D files.

3D Printing is the future. I'd like to design a fully autonomous 3D printer for cheap and fast houses, or be in a team working on one.
Brb, gonna print a rocket launcher.
[QUOTE=breakyourfac;41434126]Every fucking new machine that comes out, somebody goes "but muh jawbs!". Guess what, someone has to run/maintain those machines.[/QUOTE] but it takes less people to operate 1 machine that takes the place of 5 guys that made those parts. So in reality it actually does sacrifice jobs for more efficiency...
[QUOTE=Ardosos;41435763]Except that the amount of jobs created building and maintaining these types of machines is always fewer than the jobs that the machines replace, and usually requires a higher level of education.[/QUOTE] Then get educated.
Sounds like a technology unlock for mass effect, nice to see something scifi in reality.
This'll make spacecraft a hell of a lot cheaper if it works out, but the resulting increased ease of access might make Earth orbit damn near dangerous to get past with much more debris being created.

Bre Pettis was the host of the Make: weekend project podcast in 2007 and he talked about how in the future, he hoped that you could have a little 3d printer at home. A few years later, he made the makerbot [img]http://makerbot-blog.s3.amazonaws.com/wp-content/uploads/2012/01/makerbot-replicator.jpg[/img] i love how this shit all kinda started around the time i watched that little podcast when I was a kid and had no idea it was going to be this huge
Fuckin' sweeeeeeet. Cheaper rockets means more space missions. And that means good things for us all.
THIS SHIT WILL BLOW ON THEIR HAND
[QUOTE=Karmah;41433594]Reducing down production time by 8 months and saving 70% of the cost, I wonder if it sacrificed any quality.[/QUOTE] the great thing about high quality 3D laser sintering is that this part is probably better than one cast out of the same metal because castings can have air bubbles or imperfections from the mold, while this since there is no casting, and the mold is the actual material, and each grain is sintered togather with a laser, there are no air pockets or imperfections and when you print 5 rocket engines every single part is identical
saying "but it'll take away jobs" is an excuse so that you don't have to get smart enough to operate machines like this. the lazy way out you might say. best way to be lazy is to try and avoid it entirely, but 3D printing is the way of the future
[QUOTE=breakyourfac;41434126]Every fucking new machine that comes out, somebody goes "but muh jawbs!". Guess what, someone has to run/maintain those machines.[/QUOTE] For a lot cases no, a lot of machines just require a maintenance man who comes in and flicks them on. The world is going to see a crisis in the future were we have so much ease of technology and huge populations that simply don't have jobs, because we have machines to do it for us. Its a growing problem with no real solution yet.
