This is awesome for so many reasons: startup Open Bionics and the Disney Accelerator program have joined forces to create prosthetic limbs for kids based on The Avengers, Frozen, and Star Wars.

Madeline Stuart and Rebekah Marine took the New York Fashion Week runway to show that beauty has no bounds.

A 28-year-old man has been given a prosthetic arm he can actually feel. It seems that the robots have already learned to feel and are passing that skill—the one we thought they'd come to us for help with—back on to humans. Quick! Start trying to think of other reasons humans are useful, everyone!

Carlos Arturo Terres Tovar has designed a prosthetic arm at Umeå University in Sweden called IKO that’s compatible with LEGO. The project seeks to encourage kids to build their own prosthetics while also having fun.

When Faith Lennox was born, she had no circulation in her left forearm and doctors were forced to amputate just below the elbow when she was only nine months old. Kids like Faith outgrow prosthetic limbs quickly and they're very expensive - but now 3D printing has changed all of that.

Ariah is a 6-year-old who was born without most of her right hand. When the robotics program in Deer Creek Intermediate School in St. Francis, Wisconsin learned about this, they decided that they would do something to help her out.

Bowties are cool. Microsoft's Collective Project is another 3D printed prosthetic project that helps make prosthetic limbs more financially practical and infinitely cooler like others we've covered in the past. You can read more about it on Microsoft's blog.

Man, 2015 sure is a bust! Where are our flying cars and instant pizzas and self-effacing robotic butlers, right? WRONG! The future is here and it's ridiculously awesome (albeit more than a little disconcerting).

LIFE GOALS.

Prosthetic limbs are usually too expensive to be practical for most children (one in 1,500) born with partially formed arms. 3D printing has the capacity to not only lower the cost significantly and put prosthetics in reach for people in need, but also raise kids' spirits with some really personalized designs like this stormtrooper arm from the 501st legion.

One of the awesome things about 3D printing is that it makes manufacturing prosthetics much, much simpler to do. If you have the right design, all you need is the money for raw materials and access to a printer. The only problem is that 3D designed arms don't exactly come out looking particularly unobtrusive or real like the expensive models can—but who needs reality when you can be Iron Man?

This is not a drill: New American Jackets make synthetic leather Peter Quill coats designed to fit Star-Lords of all genders.

Earlier this year we covered "The Cyborg Beast," an open-source 3D-printable prosthetic hand that costs about $50. It looks like an Arizona man has taken the design (or something similar) and adapted it for his friend who lost three fingers in an accident.

Usually if you’re a turtle and you lose a vitally-important flipper, it’s all downhill from there. Lucky for Hofesh, a sea turtle amputee, the kind folks at Isreal’s Sea Turtle Rescue Center have developed a solution for special-needs turtles – one they developed from a fighter jet. Hofesh was tragically caught in a fishing net […]

Being born without a left hand really sucks. Jose Delgado Jr, however, is pretty used to it at this stage in his life, and has decent enough insurance that he didn't need to pay the full $42,000 sticker price for his prosthetic device. But as it turns out, he actually prefers a much cheaper prosthesis that you can make yourself with very minimal effort.

Angel is a 24 year old woman who was born without a left arm and who now owns a series of real badass prosthetics. After a picture of her carrying a bow and arrow with her bionic arm started making the rounds on Tumblr, she offered to tell us all more about how far medical technology has come in her experience.

Buttercup the duck was born with a deformed foot that he hobbled around on for most of his ducky life, causing him a lot of pain and setting up the possibility of serious infections down the line. This is basically the saddest thing ever, so the Feathered Angels Waterfowl Sanctuary in Tennessee decided to team up with NovaCopy Inc. to provide him with a new 3D-printed prosthetic foot. Buttercup's foot has been in the works for some time and gotten a lot of attention from the media, but it wasn't until last night that the completed foot was finally fitted onto his leg and he was able to work normally for the first time. Even better, there's video of his very first steps and yes, it's as adorable as it sounds.
