Nanoscale Race Car Gets 3D Printed With a Laser

Soulskill posted more than 2 years ago | from the bet-the-insurance-is-high-on-that-thing dept.

Shark 39

An anonymous reader writes "Researchers at the Vienna University of Technology have managed to perfect 3D printing at the nanoscale. What may look like a grain of sand to the human eye could in fact be a detailed racing car model, a reproduction of a famous church, or London Bridge. The 3D printer relies on a laser beam directed by mirrors through a liquid resin onto a surface. It can print at 5 meters per second, which is a world record, and the end result is only a few hundred nanometers in size. The next hurdle: printing with bio-material so we can start making our own body parts/organs."

The ONLY reason I clicked on this link and went to see the story is that I thought it was a real race car printed on a 3d printer with a laser. I didn't even care to see the shark that the laser was attached to. /. tricked me at looking into TFA and I find it abhorrent, absolutely unacceptable behaviour on the part of /. - tricking people to click on TFA link.

Oh, it's not a real car, did I mention that?

Nano car. Crap.

Hell, all the title needs is "Apple", "Raspberry PI", and "geohashing" and it's the perfect storm of a Slashdot article.

Seriously? SERIOUSLY? You must fantasize at night about drawing retarded conclusions. How about this. The next step for NASA should be to invent a hyperdrive so that we can go to the edge of the solar system and gather gold and other useful minerals. Yeah. Because 3D printing of your so-called "bio materials" with a laser is just so feasible that we can consider it our next "hurdle." If you can manage to culture enough specialized cells to....wow, I'm not even going to bother. Herp a derp, dude.

For what it's worth, at least one dude at which this should be directed is the one who wrote TFA; that's where that line originally comes from.

Samantha Wright (1324923) | more than 2 years ago | (#39330911)

TFA does superfluously mention the Raspberry Pi, if it's any help. (As an example of a reason to get a 3D printer, since it doesn't ship with a case. Total rubbish.)

Well now we just need a nano track and a shrink ray to shrink you down Fantastic Voyage-style, and you can race in the Indy 500! (millimeters)

I was thinking I could use a tiny violin but it turns out you can get them off the shelf. [amazon.com]

Re:Fake (0)

Anonymous Coward | more than 2 years ago | (#39330919)

Also that car is not on a nano scale. 250 um is huge -- it's a quarter of a millimeter with features easily seen with the naked eye. There are common resistors smaller than that.

Re:Fake (2)

fahrbot-bot (874524) | more than 2 years ago | (#39330949)

Sorry to hear you're disappointed. Perhaps they can print a nano-violin and pretend to play it just for you :-)

roman_mir (125474) | more than 2 years ago | (#39330985)

I bet it's going to sound crappy too, it'll be a rip off, just like this 'vehicle', and it's not really nano either - too big for that.

Though you more likely meant:

This product is not yet being sold to raise money for ron paul, therefore it is evil and abhorrent. I must hate it even though it has done nothing bad to me. All hail lord ron paul.

Perhaps you accidentally swallowed a small nano model of something when you were trying to drink more kool-aid? That might explain why you forgot to pledge eternal unquestioning allegiance to your lord and savior in your post.

Nano-scale 3D printers don't come cheap, and there's a lot of space on the car to cover.

Sure, it'll make Jimmie Johnson go on for an hour as he lists the sponsors on his Eyelashes, but it's not like you had a race to watch.

shadowrat (1069614) | more than 2 years ago | (#39330611)

I was hoping maybe the printer was also tiny. I live in a tiny apartment and a nano scale printer would be awesome. I'd love to have a 3d printer at home, but so far they all seem to be big counter hogs.

Not really nanoscale (5, Insightful)

wjh31 (1372867) | more than 2 years ago | (#39330661)

It's stretching it a bit to call it nano-scale. The legend on the images puts the models in the region of 100um. 0.1mm is not really nano-scale, unless the hair on our head is nano-scale. With around 200 lines per layer, we're still talking about hundreds of nanometers for the print resolution.

small is not nano, regardless of how much SEO you're after

Re:Not really nanoscale (2)

roman_mir (125474) | more than 2 years ago | (#39330731)

The only legitimate question remains, and it's this:

The DETAILS are on the nanometer scale, though, pedant...

So is everything. So what?

Re:Not really nanoscale (1)

wjh31 (1372867) | more than 2 years ago | (#39331393)

as said in the OP, details in TFA suggests resolution is hundreds of nanometers. If NASA/ESA came up with a picture of the moons surface with half kilometer resolution, you wouldn't call it meter scale

Re:Not really nanoscale (0)

Anonymous Coward | more than 2 years ago | (#39331675)

actually it would be called 500 METER resolution, not half kilometer resolution.

jackbird (721605) | more than 2 years ago | (#39334607)

I did some 3D modeling work for these guys back in 2009 for an artist who was using their process to fabricate a very, very small installation.

For one of our tests, we printed a Statue of Liberty 90 naometers tall and 23 naometers wide. They used an electron microscope to document it.

Nanoscale enough for me.

Re:Not really nanoscale (0)

The whole models are in the micrometer scale, but the details of the models are in the nanometer scale.

It prints at micro scale. Willard Wigen [willard-wigan.com] is unimpressed.

Re:Can We Take Back Nano? (1)

wbic16 (632102) | more than 2 years ago | (#39334909)

Apparently the term "nano-scale" means that your manufacturing process has features measured in nm. Even if that is 400 nm or 1000 nm it seems. Example: https://nano-cemms.illinois.edu/materials/3d_printing_full [illinois.edu] Quote 1: " . . . incredibly thin polymer layers (on the order of 400 nm) . . . " Quote 2: "This activity demonstrates the basic challenges of nanoscale engineering and manufacturing."

They are solving the same problems I solved in the '80 with high precision laser control. Laser shows high speed AND high accuracy, they probably could have bought the computer scanning controls off the shelf for a couple of grand.

5 meters per second and it's how long? (0)

Anonymous Coward | more than 2 years ago | (#39331367)

so it printed in like, a serious fraction of a second?

Re:5 meters per second and it's how long? (1)

almitydave (2452422) | more than 2 years ago | (#39332855)

I was confused by this as well.

The printer isn’t slow, either. In just 4 minutes it can print 100 layers consisting of 200 lines per layer. That translates into five meters of polymer printed in one second, which is actually a world record.

So 20,000 lines in 240 seconds comes out to 83.3 lines/sec, making each line 60 mm wide? Either I'm misunderstanding (always a strong possibility) or there's a typo there somewhere.

I wonder if it will be possible to make the printed resin conductive? Or even better variably conductive.

reproduction of a famous church, or London Bridge.

It's TOWER BRIDGE. ffs. You can tell by the, um, towers.

How about we start referring to your landmarks as the Statue of Eiffel, or The Silver Gate Bridge, or the Quite Big Canyon?

I wonder if this can be scaled up (1)

hackertourist (2202674) | more than 2 years ago | (#39336991)

Current 3D printers have a resolution limit on the order of 0.2 mm. If this can be improved by even one order of magnitude, you're getting to the point where objects look perfect to the naked eye.
