People Create 3D Hats For Sea Urchins After Finding Out They Use Shells As Hats

When Twitter user, @ok_girlfriend, who also happens to be a biologist, revealed that she just discovered that, "sea urchins naturally use shells as hats to make them feel safer and camouflaged so some aquarist had the genius idea to make them tiny hats." The aquarists 3D printed hats for these little sea creatures and it's indeed genius! We can't get enough of these little sea urchins donning tiny hats! 

Lately, we've been bunnies in hats, snakes in hats, and even hedgehogs in hats -- seems like we have another animal to add to the tiny hat-wearing collection

3D-Printing Technology Was Used To Replace The Skull Of a Dog With Cancer

Researchers at an Ontario university used 3D-printing technology to replace the majority of a dog's skull in what's believed to be the first surgery of its kind. The owner of Patches, a 9-year-old dachshund, said the dog had a brain tumour the size of an orange that would have been fatal if not treated.

Using 3D printed prosthetics, Derby the dog can now walk and run for the first time in his life.

He was born with small forearms and no front paws like a furry little T-Rex, and he could only move around on soft surfaces as a result of the deformity.

So 3D Systems created some new legs for him using a 3D scanner and a multi-material 3D printer that could build both the sturdy base and comfortable rubber cups.

“He runs with Sherri and I every day, at least two to three miles,” said his owner Dom Portanova. “When I saw him sprinting like that on his new legs it was just amazing.”

Watch him in action in the video above.
