3D Indy: Nano Racecar

3D Indy: Nano Racecar

• This model of an Indy Car, about the width of a human hair, was made in 4 minutes using a 3D printer.  Printing three dimensional objects at a nanoscale with incredibly fine details is now possible using two-photon lithography.  Scientists at Vienna University of Technology have broken the record for speed printing, going from a few mm/sec to 5 m/sec! This is done using precisely controlled mirrors to focus a laser beam on printed resin. Because the resin hardens only when activated by 2 photons of light, at the very center of the laser beam, solid material can be created anywhere in the liquid resin instead of only at the surface.  Potential applications include making scaffolds to build human tissue or body parts.

• Meanwhile, at this weekend’s  Grand Prix races, real life Indy Cars will roar through downtown Baltimore, looping through 2 miles of familiar city streets at speeds >175  miles per hour.   (I drive the same streets at a slightly more sedate pace on my way to work every day.) This uniquely urban track includes 12 turns over 200 bolted-down manhole covers in the heart of a 300 year old city, past the picturesque Inner Harbor along the Chesapeake Bay. Watch what happens when Tony Kanann’s breaks fail  at 180 mph during last year’s Grand Prix in Baltimore. Amazingly, the drivers walk away unscathed. Tony Kanaan and Helio Crash at Baltimore

    Haha, I knew you would pick that up 😉

  2. One of these days, I suppose we will figure out how to print ourselves a heart or a kidney given the kinds of resolutions we are talking about here. Wouldn’t that be a wonderful thing?

  3. Rajini Rao says:

    Suhail Manzoor , I agree..there are already attempts to combine 3D printing with tissue engineering. Meanwhile, we can play with nano Indy cars 🙂

  4. Rajini Rao says:

    I saw that too. Gnotic Pasta argued that there is a lot of hand craftsmanship involved to make a good one, although I guess something destructive can readily be made.

  5. thats easy Rajini Rao , the destructive bit. All they have to do is figure out how to print the printer 🙂

  6. Rajini Rao says:

    Feisal Kamil , thanks. Deleted and blocked after the comments did not stop upon simply ignoring.

  7. Bill Collins says:

    I am still in shock, awe and delight at what 3D printing can do. This is even more amazing.

  8. Rajini Rao says:

    Bill Collins , there are images of tiny Tower of London and St.Stephens Cathedral models in the link with even more detail 🙂

  9. Amazing. It should be useful for dentists.

  10. I can’t belief, but I think I have to. Thanks for this post.

  11. Chad Haney says:

    Good morning all. Gnotic Pasta you should make a separate post about the plastic AR15 from the 3D printer.

  12. Mary W. says:

    Fast cars & cool hair! This was an amazing post, Rajini Rao! Science IS FUN!!!

  13. Of course this is an amazing technology.

  14. Rajini Rao says:

    thanks, Mary! If you do post on that, Dan, do tag ScienceSunday and post the link here:)

    I’ve found this page talking about ‘print’ organs.

    Definitely…”off the scale”  “:D

    it is unbelieveable ..width of hair n so in 4 min…..
