A UNIVERSITY has created a robotic hand that can move like a human.
Seoul National University researchers have come together to create a functioning robotic hand, that was made using a 3D printer.
The 255g prosthetic known as the ST3P hand, was designed to be lightweight and low cost at $500, according to a recent article published by the team.
It has nine finger joints and was created using single-step 3D printing.
ST3P takes less than 10 minutes to put together, which is incredibly fast compared to other 3D-printed prosthetics.
The hand is also fully functional and can do basic tasks by using a pulling force of 48 N and a grasp strength of 20 N.

When speaking about the product, researchers reveal they are very hopeful about their creation.
"The simple manufacturing of the ST3P hand could help us take one step closer to realizing fully customized robotic prosthetic hands at low cost and effort," they explained.
The research team decided to utilize single-step 3D printing, due to its ability to create complicated designs without the need to assemble them.
Using this printer has made it easier to make ready-to-use moveable mechanisms.

The team has encountered challenges with 3D printing in terms of limits in precision, as well as not being able to create a tightly mated moving surface.
To combat this they designed joints that have a gap in between the components, in order to help the hand create its impartial motions.
"We simulate the anatomical structure of the human finger joint and implement a cam effect that changed the distance between the contact surfaces through the elastic bending of the ligaments as the joint flexed," they explained.
