By the end of World War I, there was no shortage of post-war amputees, who were amputated in field hospitals or medical facilities behind the lines. Prosthetics had existed for centuries before the war, but the sudden influx of amputees from all directions overwhelmed medical services. Even if the prosthesis restores their basic mobility. But these amputees need to be reintegrated into society, find jobs and support their families. At that time, the group didn't want anyone to know they were amputees. When they start practicing, a lot of them walk in the back door because they don't want anyone else to know they're going to prosthetic rehabilitation.

In the early 20th century, artisans thinned, tied or forged prosthetic limbs to fit the wearer. As time goes on and society advances, the stigma of having prosthetic limbs is slowly improving, more amputees are becoming aware of high-end prosthetic alternatives, and the line between "capable" and "incapable" people with disabilities is starting to blur. Their prosthetics are now practical and futuristic enough that they don't need to be hidden, but can be worn with confidence.

3D-printed prosthetics mean more than just lowering the cost of prosthetics. Its functionality is also an important part of life. Users such as 11-year-old TillyLockey and a range of arms inspired by Iron Man, Star Wars and Frozen have attracted global media attention. Children may have low self-esteem and lack of limbs or rough prosthetics make them easy markers for bullying. Previous prosthetics were simply 3D printed in every possible color. Designers make them black, gray, and even skin color. But once designers start to really focus on this co-creation approach and run workshops for amputees, they hear these real trauma stories of young adults growing into adults with huge feelings of inferiority due to their physical differences. If they wear make-up hands or prosthetics at school or in public when they are young, it makes them want to hide their prosthetics even more.

This is a very negative body image for them and continues into adulthood. It's not the fault of the amputees themselves: it's how others see them and how others treat them. It is clear that at school any differences between pupils will set them apart, so everyone is trying to adapt. So, they thought, if they're going to be treated differently because they're different, they'd rather not have Victorian prosthetics. They said they wanted something really cool and they wanted it to be accepted in such a friendly way that people would look at it and say, "Oh my God, what's that?" Instead of, "Oh, what's wrong with you? Tell me about your amputation."

From physical disabilities to prosthetic augmentation

Advances in prosthetics raise an obvious question: When will bionic limbs surpass the ones they're replacing, based on decades of science fiction predictions? If anything, would we "enhance" our bodies with bionic prosthetics, ideal upgrades for able-bodied people, stranger than facelifts or tummy tucks? We still have a long way to go in prosthetic technology and how it matches up with human capabilities. Our technology is not that far down the road to tech-sensing prosthetics. It's not amputation talk, it's not medical, it's not rehabilitation advice, it's something that makes you stand out for a good reason. Make people admire you and want to be you.

Designers think prosthetic technology of the next step will be to human auxiliary equipment, in a robotics symposium, many companies have been promoting can wear like put on a suit of equipment, it makes the wearer more powerful, but it is not to replace the arm, but in the arm or back or a device is placed on the body, so that you can work with their own hands, Make the wearer more powerful like Iron Man.
