Based on the research of Robert Full, this tiny sheet of plastic has even tinier hairs. Not tested yet, but based on proven research. A gecko's foot uses microscopic hairs to stick to surfaces by creating a kind of a super friction. This object does the same thing, only on a smaller scale. This sheet of plastic has 1,000 tiny spires, and is only 6 square millimeters. Though not as strong as the force from a gecko's foot, the amount of hairs on a gecko's foot can hold up 250 pounds. Considering that, this should still be able to hold up a decent amount. From the information that I have received, I think it should print, but there are no guarantees.


Use a Replicator for this. For it to be accurate, it is best to make the layer height .01. From what I have heard, it seems to be possible to make it that precise on a replicator. Will be able to print and test anywhere in between 4 and 6 weeks. I promise I will test it, but until then, try printing it yourself. It is best to use PLA instead of ABS, because it is more flexing.

I love your imagination but yeah the gecko's appendages are working on the nano scale. That being said - the idea of printing velcro type surfaces intrigues me.

Yeah, this is something I made a while ago when I didn't really know what I was doing. It does work as a sort of velcro on almost all fabrics, but I was kind of stupid to think it would work. I've been doing much more interesting things on my other account, Pink_Iguanas, if you're interested in checking that out.

That kind of looks like the knobby "velcro" we use at work but much smaller.

The Gecko's foot hairs are molecular sized, and make use of the van der Waals force.
