3D Printed Prosthetic Hand in 4 Steps!

Introduction: 3D Printed Prosthetic Hand in 4 Steps!

This project is a prosthetic hand that was printed by me, I am seeking to explore some more knowledge about prosthetics and 3D printing. Although this isn't the best project, it's a great way to have some hands on experience and learn how to create one of these hands successfully.

This is a low-cost prosthetic hand that is easy to make, the main issue per say, is the time it takes to print all of the items. But other than that, this hand is quite easy to make and doesn't take much to make. 3D printing is a very big part of the society nowadays as it is a very technologically advanced way to make things quickly, with the accessibility at your fingertips.

All of the supplies are included in a kit, if you'd like to purchase the kit visit: https://shop3duniverse.com/products/e-nable-hand-assembly-materials-kit-cyborg-beast-edition?aff=2#

Step 1: Different Variations of the Hand

These are just a few of files used in this.

Step 2: Scaling

I've provided a scaling chart to ensure that you have the right size and measurements to fit the person in need.

For this you must scale each of your items to the correct size, I have set all of my pieces to 150%

Step 3: Start Printing Your Items

This is most of my project, as most of it is 3D printed.

I printed these with PLA filament and on standard speed, these all range from an average of 2 hours to 8 hours on the biggest piece.

Step 4:

Although this isn't my own video, I'd like to include this in here as this is a great video showing you how to assemble and install all of the parts.
