Often depicted in 2D it’s an impressive example of an object which is seemingly impossible to create in 3D.
Well, someone has ‘kind of’ managed it and if you look at the picture above you’ll see the version I 3D printed and photographed myself. This illusion has been around since 1934 when Swedish artist Oscar Reutersvärd first created it.
The only hard part is finding the exact angle and distance from which to view the object to create the perfect illusion.
I struggled with this part so that’s why I created the video, to make your life a little easier.
So you might be asking, how did I manage to 3D print an object which is supposedly impossible to create?
All is revealed in this short YouTube video…
As you can see from the video it’s still an illusion and this ‘impossible object’ really is still impossible to create properly. I think this 3D illusion is still pretty impressive so why not try it for yourself?
Here’s the link to download the Penrose Triangle from Thingiverse.
By the way, you may have noticed that this is a quite short blog post compared to my usual ramblings. Well, I loved this illusion so much I really wanted to get it to you as soon as possible so you can try it too.
Don’t worry, I have loads more 3D printing antics on the way to add to my 3D Printing Beginner Series. As ever, my MakerBot hasn’t had much rest over the last few weeks, so watch this space.
