Has the "Impossible Triangle" Been Made Possible with 3D Printing? - 3DPrint.
comHave you ever stared at an M.C. Escher picture until you grew dizzy or simply marveled at the way Escher configured angles and drew objects to trick the eye? Well, there’s no question Escher is a master of illusion, beckoning us to an imaginary world of complexity and perspective that teaches the lesson that not everything is “as it seems.” Or, better yet, things can appear as more than one thing at different times depending on how you look at it. The lesson of the optical illusion is a tough one: things aren’t what you think they are. Or, more specifically, things can be more than one thing at the same time, and your mind and sight can be tricked by something rather simple in the end.
I am pretty sure that my first encounter with an optical illusion was the picture of the old woman/young woman illusion. If you take a neck for a chin, a young Victorian looking woman, glancing sideways, becomes an old woman with a very distinctive nose and face. Mastering the feat of designing images that can literally look different than what they are is the point of optical illusions, and it now appears that someone has achieved the impossible and printed an “impossible triangle” that has one of the bases of Escher’s work and a great challenge for mathematicians and physicists alike.
One interesting aspect of Escher’s optical illusions involves the mathematical conundrum of the “impossible” or “Penrose” triangle — an object that appears in Escher’s work, like his famous print “Waterfall” (see right). Recently the same illusion has been 3D printed, too. In 1934, the Swedish artist Oscar Reutersvärd created the first “impossible” or “Penrose” triangle and it was popularized in the 1950s by the mathematician Roger Penrose who explained that it is “impossibility in its purest form.”
Why is it impossible? Because it is a two-dimensional object made to look three dimensional — depending on the angle you perceive it at. An object of much fascination for science nerds, the impossible triangle presents itself as an object that seamlessly conjoins different sides of a triangle, but that depends on the angle you look at it.
The verdict is still out on whether this 3D printer succeeded in achieving the impossible. One “spoiler” in the post comments suggests that this is, of course, an optical illusion and if it was photographed at a different angle it would look quite different.
The “spoiler” even claims that the original poster of the impossible triangle provided different photos on reddit (see below). Okay. But if the impossible triangle has always been impossible, doesn’t the original poster deserve some credit for 3D printing an illusion?
If you want to figure this out for yourself, you can download an STL file of an impossible triangle from Thingiverse. As one person commented, “you can see the mark of where it ends. Good illusion though.” And that appears true. There’s another version of an impossible triangle, also on Thingiverse, that relies more obviously on the viewing angle to preserve the illusion.
The creator of the 3D printed impossible triangle gets credit from me for an imaginative take on a illusory conundrum that has baffled some of the great artistic and scientific minds.

The weirdest things you can 3D print
#SIU_for_life 06/21/2020
The future is already here: if you can't buy something, you can just print it.
The 3D printer is one of the most revolutionary technologies of the last five years. Now with its help you can print absolutely everything, the main thing is to have the right ingredients. Already today, a 3D printer is becoming an integral part of science and technology, but tomorrow it will be in every home.
Sweets
Rooms and houses feeldesain.com digital-grotesque.com
Designers Mikael Ansmeyer and Benjamin Dillenburger printed a 16 m2 room from fine sand. The room was created in the style of the scenery for the film "Alien" and has no corners at all.
Furniture contourcrafting.org emergingobjects.com
Emerging Objects creates futuristic-looking designer furniture using 3D printing. The bench in the photo is made from a mixture of cement, compressed plastic and concrete, making it super strong. Saltygloo is an unusual lamp printed from natural salt.
Snowboard designboom.
com
California company Signal Snowboards has developed a series of 3D printed snowboards. The board consists of several parts, and its edges are slightly bent up - for maneuverability.
Musical instruments odd.org.nz
Professor Olaf Digel from New Zealand created a line of so-called ODD guitars. Digel says: “3D printing technology makes it possible to produce impossible shapes. For example, one of my guitars is shaped like a web with spiders crawling inside." Renowned violinist Joanna Vronko was invited to test an "artificial" violin. It turned out that the sound of such an instrument is drier, the mass is larger, but the violin is printed on a 3D printer.
Nails thelasergirls.tumblr.com
Creative Nails is a new project by Sarah Awad and Demera Ford. These cost from 21.76 euros and you can buy them via the Internet. Leo Marius. Now anyone with a 3D printer can download files, print, and assemble a camera in about 15 hours.
