Gripen's 3D printed skin tested in Sweden

On March 30, Sweden tested 3D printing of the skin of the JAS-39 Gripen fighter. The aircraft made a successful flight with a 3D printed external hatch.

Saab, the manufacturer of these combat vehicles, announced this on its Twitter page.

We successfully flew a 3D printed outer hatch on the Gripen to see how the technology could be used to repair damage on the battlefield.

- said in a statement.

The test flight, which takes place over the Saab plant in Linkoping, Sweden, lasted half an hour. The experiment was carried out by the company's employees together with the military personnel of the Royal Swedish Air Force.

According to the press service of the manufacturer, the material for the manufacture of the part is PA2200 nylon polymer. They said that with the help of 3D printing, the military will be able to repair fighters in the field, away from technical assistance points. This technology will be especially in demand when conducting military operations in remote regions.

The JAS-39 Gripen is a fourth generation multi-role fighter produced by the Swedish company Saab since 1997. In addition to Sweden, European countries have it in service with the Czech and Hungarian Air Forces.

Swedish Air Force is very strong

[Roma 1977]

Yes, stronger than in Ukraine - the second strongest army in Europe!

Deep remark. I'm shocked !!!
Now on the topic - the hatch was blown off by the oncoming wind? Oh, no, they just replaced it with a regular fastener and a regular lock. So they could have put plywood. If there is no other damage. And if there is, then 3Deshit is no longer only the hatch, but all of its components. And what is under it, most likely, too. It would make all the sense, everything would be printed at the factory.

[Holuay T.O]

How many fighters should we deploy on the Peter-Tallinn-Vyborg direction? Not less than 800
And the Swedes have 4 more drills and 4 rubs
Are you overwhelmed? And then there is Norway with f 35 and f16 and Finland with f 18

This is a turn of events! In reality, Sweden is American lackeys.

Headline -Gripen 3D printed skin tested in Sweden.
According to the text - We successfully flew with a 3D printed outer hatch on the Gripen to test how this technology can be used to repair damage on the battlefield ... with the material to craft the DETAILS ...
Didn't I understand something?

[tlauicol]

Find a video on YouTube or Twitter. Yes, and the news does not interfere with the video insert.
I'll come home, I'll insert it from the computer, everything is clear there

The usual heading-enticement, from which one can imagine that there the entire glider was printed on the printer.

Yes, everything is clear In gripena, the hatches come off in each flight, the BAO does not have time to carry spare. We have to print locally. It's funny what they will print thermally loaded parts from?

[rotmistr60]

This technology will be especially in demand when conducting military operations in remote regions.

Mandatory, because when carrying out real hostilities from Swedish aircraft, it will tear off (damage) only the outer hatch. It's irony. Another question is interesting - how many "tugriks" will it cost to deliver a 3D printer, materials to the place of hostilities and install equipment?

There, the 3D printer itself costs as much as 100/500 ordinary duralumin covers.

How many years this 3D printing advertisement has been going on. I still have not seen a real assembly for an airplane subjected to stress, 3D printed. Not a single bearing, pilot light, all caps and hatches ......... ............

[voyaka uh]

NASA prints nozzles for space engines.
American private firm Rocket Lab prints fully space rocket
on printers. 17 successful launches.

17 successful launches.

Can you tell me where to look at the information about the launches?

Relativity Space has been awarded a contract to launch six Iridium satellites. The purpose of the launched vehicles is to replace the failed vehicles. The launch site is the Vandenberg base. The Terran 1 rocket was announced as a launch vehicle. The launch date is no earlier than 2023. Each of the rocket launches will deploy no more than one satellite of the Iridium Next series. The satellites to be launched were built as part of the 75 satellite launch program (seven Falcon 9 launches) and are now in storage.
“The modernized Iridium satellite constellation is performing incredibly well, but it makes sense to have a cost-effective and affordable launch option to meet the replenishment challenge,” said Iridium CEO Matt Desch.

Not serious how it happened, where to look at the information about the launches

[Basarev]

A very good idea, but it needs to be developed. This is how I see it in the future: at the entrance there are bags of powder, at the exit is a finished product.

[AVA77]

3D printing is good for complex shaped parts and with a 3D model.
There is no point in printing a frying pan, it is expensive and time-consuming, easier and cheaper to make by stamping.
Printing sheets doesn't make sense at all.

[voyaka uh]

Somehow the Swedes woke up late.
3-D printing has long been used for emergency production of spare parts.
right at military bases.
XNUMXD printer factories appeared on American aircraft carriers and UDC.

[tlauicol]

3d patch making and flying

[Ryaruav]

nafig that printer if the mold (it already has these parts on it) churns them out at a speed until no printers shine

[voyaka uh]

But 3-D printing can produce parts of unthinkable complexity.
With dozens of asymmetrical spiral-shaped internal channels, for example.
There is no way to make a mold for such. Impossible to cook and casting.

[Ryaruav]

buddy, you probably know a spiral toy that goes down the stairs itself and this is up to the printers, but the outer hatch of the fighter (I served as an aircraft mechanic) is simplicity itself, and the curvature of the surface is a parabola, or metal stamping or molding of plastic masses

[voyaka uh]

The outdoor hatch is an example that I laughed at myself.
Here 3-D is overkill, you are right.
I spoke in general about the advantages of 3-D printing in the manufacture of uniform monolithic
parts of an extremely complex shape.

[Ryaruav]

my son-in-law is a high-quality IT specialist, he makes some kind of plastic parts for Opel on the Tride, well, why do you melt steel on a printer oh, note the steel should turn out x12 what you can

[Ryaruav]

Well, youth, decipher the composition of steel

[voyaka uh]

It is called "Direct Laser Sintering".
Pictured by NASA: firing test of a rocket engine nozzle.
The nozzle is made by 3-D printing.
These nozzles have already successfully flown into space.

[Cat]

What if you need a piece of a slightly different shape?

[yehat2]

interesting opportunity for renovation.
we, especially the MIG with its repair logistics, should think about it.
This can dramatically improve the position of samples sold abroad.
