CLEARWATER, Fla. — When 10-year-old Annika Emmert patted Winter the dolphin’s smooth back at the Clearwater Aquarium on Thursday, she thought that was the best part of her morning.

She was wrong.

Cozi Zuehlsdorff, the actress who starred with Winter in the “Dolphin Tale” movies, set a cooler next to Annika. The girl opened it, thinking it was dolphin food.

“I was really surprised,” said Annika, whose eyes welled with tears when she saw what was inside. “I was like, that doesn’t look like fish.”

Instead, Annika – who was born without part of her right arm – was shocked to see a custom-made prosthetic limb, decorated with bright flowers. A bionic limb, if you will, that’s controlled by Annika’s muscles and electrodes.

The most remarkable part: The limb was created using 3-D printing technology.

Limbitless Solutions, an Orlando-based nonprofit run and staffed by University of Central Florida engineering students, made the limb. The group’s mission is to “print” prosthetic limbs for children and to encourage other companies and nonprofits to use the technology by providing the plans and software.

Printing Annika’s arm took about 40 hours. Each piece is modular: When Annika grows, she’ll get upgrades in the form of larger parts.

“That’s the beauty of 3-D printing. You can just print a new, longer finger, a new, longer forearm, and we can keep the electronics the same,” said Albert Manero, Limbitless’ executive director.
