watched the rollout of the new spaceX vehicle

they had a number of its components out to show the crowd
one was their latest rocet thruster
the big ones used for landing this thing

turns out its 3d printed

Printing the metals of the future


3-D printers can create all kinds of things, from eyeglasses to implantable medical devices, straight from a computer model and without the need for molds. But for making spacecraft, engineers sometimes need custom parts that traditional manufacturing techniques and standard 3-D printers can't create, because they need to have the properties of multiple metals. Now, researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are implementing a printing process that transitions from one metal or alloy to another in a single object.

"You can have a continuous transition from alloy to alloy to alloy, and you can study a wide range of potential alloys," said R. Peter Dillon, a technologist at JPL. "We think it's going to change materials research in the future."

Although gradient alloys have been created in the past in research and development settings, this is the first time these composite materials have been used in making objects, such as a mount for a mirror, said John Paul Borgonia, a JPL mechanical engineer.

Why would you need to make a machine part like this? Say you want a metal object where you would like the ends to have different properties. One side could have a high melting temperature and the other a low density, or one side could be magnetic and the other not. Of course, you could separately make both halves of the object from their respective metals and then weld them together. But the weld itself may be brittle, so that your new object might fall apart under stress. That's not a good idea if you are constructing an interplanetary spacecraft, for example, which cannot be fixed once it is deployed.

SpaceX Taking 3D Printing to the Final Frontier

By Elizabeth Howell,
Space.com Contributor
| August 21, 2014


The private spaceflight company SpaceX wants to launch astronauts into space in the coming years, and it will enter the final frontier with an innovative technology: 3D printing.

California-based SpaceX is using additive manufacturing, as 3D printing is also known, to build the emergency escape rockets on its new manned Dragon spacecraft. The capsule, known as Dragon Version 2, is SpaceX's entry in NASA's competition for commercial manned spacecraft to ferry astronauts to and from the International Space Station.

SpaceX sent its first 3D-printed part into space early this year. The part, a rocket engine main oxidizer valve, flew aboard SpaceX's Jan. 6 launch of a Falcon 9 rocket carrying the commercial Thaicom 6 telecommunications satellite to orbit. The valve flew inside one of the rocket's Merlin 1D engines.

[video at the link]


"The mission marked the first time SpaceX had ever flown a 3D-printed part, with the valve operating successfully with high-pressure liquid oxygen, under cryogenic temperatures and high vibration," SpaceX representatives wrote in a statement.

The concept of 3D printing in space has received extensive attention in industry circles in recent months. NASA plans to send a 3D printer produced by California-based company Made in Space to the space station this year, and the European Space Agency has mused about using 3D parts to build lunar bases. Despite those plans, a recent National Research Council report said the technology is still in its infancy and that the materials science behind manufacturing in space is poorly understood.


SpaceX has used 3D printing to build the SuperDraco rocket engine for the company's Dragon Version 2 manned spacecraft. The eight SuperDracos on the capsule are designed to double as a landing system, or as an escape system in the event of a launch emergency.
Credit: SpaceXView full size imageSpaceX has spent three years evaluating the fast-growing technology, particularly for use on the Dragon spacecraft. A 3D-printed SuperDraco engine chamber, which will be used in the escape system, passed a firing test at full thrust in late 2013.

"Printing the chamber resulted in an order of magnitude reduction in lead time compared with traditional machining — the path from the initial concept to the first hotfire was just over three months," SpaceX representatives stated.

The 3D valve inside the Falcon 9's rocket engines will also be more efficient to manufacture, SpaceX added. After extensive testing, the 3D part is now certified to fly alongside regularly manufactured materials.

"Compared with a traditionally cast part, a printed valve body has superior strength, ductility and fracture resistance, with a lower variability in materials properties," company representatives stated. "The [valve] body was printed in less than two days, compared with a typical castings cycle measured in months."

Just to add to Ben's post

"the SuperDraco engine chamber is manufactured using state-of-the-art direct metal laser sintering (DMLS), otherwise known as 3D printing. The chamber is regeneratively cooled and printed in Inconel, a high-performance superalloy that offers both high strength and toughness for increased reliability."

The Syqe Inhaler: 3D Printing Meets Medical Marijuana

This is not about a 3D printed "MarioBong," although that has been done. It's about a 3D printed pocket-sized metered-dose cannabis inhaler/vaporizer.

The device, called the Syqe Inhaler, was created by Israeli venture Syqe Medical and is Wi-Fi enabled.

Vaping Vs. Toking

Inhaler/vaporizers have virtually replaced old standbys such as the joint and the bong for both recreational and medical marijuana use.

One of the better-known units, the Puffit, has enjoyed widespread use and adoption because it looks just like an asthma inhaler and vaporizes the “herbs,” making them scentless, according to the manufacturer.

Dose Control

The Syqe Inhaler was designed to give medical professionals more control over dosage in an effort to help patients on medical marijuana walk the fine line between "pain control" and "impairment."

Syqe Medical founder and CEO Perry Davidson told The Wall Street Journal, "We are directly manipulating the human psyche in a very precise manner. A physician could prescribe a custom-tailored, individualized treatment for that patient, and not have a hit or a miss, but a very close hit on the accurate dosing that the patient required."

Wi-Fi Enabled

The device, which can be connected to a smartphone or tablet via Wi-Fi, would allow both patients and doctors to monitor and administer the proper dosage in real time.

Being able to upload real-time data would also allow researchers to determine proper dosage under different circumstances.

Using Wi-Fi, the smartphone or tablet app could automatically administer optimum dosage to patients without resorting to a long trial and error process.

3D Printing Speeds Process

According to Plastics Today, 75 percent of the parts in the Syqe device were printed on multiple Stratasys, Inc. (NASDAQ: SSYS) 3D printers.

This sped up the manufacturing process and moved the project into clinical trials much quicker than if prototypes would have been created through more traditional means.

Davidson told Forbes multiple Stratasys 3D printers were required to print the four main components of the device: shell, chassis, airway and thermal housing.

The company said the Syqe Inhaler would be available for home use sometime in 2015.

now they have a printed car with 49 parts for £11,000 . i think thats expensive when you can buy a second hand car much cheaper and probarley more safer...

they have to do that up in layers
amazing they can get em so strong!

a fucking rocket engine!!!

wonder if they have to stop and clean burs off the side as their progressing

or is the process so precise there just aint no need?

absolutely stunning!

10 times as fast as anything going AND a much smaller machine
its litterally pulls the part out of a liquid pool of the starter material.

light in the bottom of the pan solidifies exactly what "part" of the part your making needs to occur as it breaks the surface

gotta see this!

so if you wanna print out whatever, how do you get schematics for it... trial and error!??
