How I 3D Printed Another Amazing Illusion

by Jason King on January 25, 2015

Penrose Triangle ParadoxJust recently I’ve been getting a little carried away with 3D printing seemingly impossible objects.

You might want to call these paradox designs or optical illusions but whatever label you put on them they’re very interesting to print and impressive to look at.

If you recall a few days ago I wrote a short blog post with an accompanying YouTube video explaining a 3D printed illusion called the Penrose Triangle.

Yesterday I found an even better version of this and after taking a great photo of it, again I felt that I really needed to share this with you sooner rather than later.

If you haven’t already, take a good look at the photo at the top of this blog post and you’ll realise that this object is impossible to make, but somehow I did.

Of course it’s an optical illusion but an impressive one at that. I promise that this photo wasn’t doctored in any way, I literally held up the object in a darkened room with the correct lighting, took the photo and included it in this blog post, completely unaltered.

If you’re in any doubt and you have access to a 3D printer, pop over to Thingiverse, download the Penrose Triangle Illusion  and try it for yourself.

What’s so surprising about this illusion is that the object used to create this illusion hardly resembles how the resulting illusion looks, when the correct view point and lighting are applied.

Penrose How to MakeAs you can see from this photo of the exact same object, without the correct viewpoint and lighting this looks like some random patterned triangle.

Also, in the illusion all the points of the cubed that look like they’re closest to you are actually furthest away in reality, it’s just the lighting that makes the convex shapes look like cubes.

I hope you like this illusion and don’t mind me publishing these as I find them. As I said before in my original Penrose Triangle Article from a few days ago, I’ve been busy printing loads of other stuff too.

I will be reporting on these soon but if you want to see my 3D printed objects literally moments after I make them you can Follow Me on Twitter or Like My Facebook Page, where I post all the best stuff as I make it.
