K+ 3D Printed Prosthetic Arm Kits

Prosthetics are artificial devices designed to replace a lost body part, for example a hand or a leg, which may be lost in an accident, trauma, disease or birth defect. There are several types of prosthetics such as aesthetic, which is meant to look like lost limb but not providing any functionality. With 3D printed prosthetics gaining popularity with the introduction of consumer level 3D printers, practical applications of these prosthetics have also been increasing. Our Role at K+ 3D print is to highlight the capabilities of 3D printers by offering the most affordable 3D printed prosthetic arm kits.

K+ 3D Printed Prosthetic Arm Kits


Project Objective

  • Must be easy to build and use
  • Must be a High quality device with affordable Price
  • Must be easy for kids to learn
  • Must be practical and reliable in developing countries

3D Printed Bionic Hand

  • Every finger can be controlled separately.
  • Special spring damping structure, effective protection
  • Compatible with Arduino and the other Micro controller

It consists of 5 micro servos, joints and one hand base. The special mechanical structure makes every finger can be controlled separately, all can move in certain range. And every finger has spring damping structure, it will protect the robotic hand from the mechanical stress effectively.

3D Printed Prosthetic Arm (with myoware muscle sensor)

The hand is controlled by EMG signals. These signals are read by MyoWare sensor placed on surface of the skin above muscle to be read. For best signal quality the sensor needs to be placed above muscle correctly.

Myoelectric (Myoware), which is a body-controlled prosthetic with some sort of sensor, and an activity specific prosthetic designed for certain activity, for example, spring type leg for running, hook for holding boat paddle etc. Myoelectric prosthetics have advantage of aesthetics and functionality. Myoelectric prosthetics is using electromyography signal generated by muscle contractions . By placing sensors on forearm, the patients can learn how to voluntarily contract specific muscle groups to activate the prosthetic palm to close and open fingers or wrist.

 The one of project targets was to create affordable prosthetic hand for patients in developing counties.

   The main goals are to create low cost 3D printed prosthesis hand controlled by EMG signal from upper arm muscles and a 3D printed bionic hand that could be used in educational and experimental purposes. All goals have been achieved with different levels success. The hand control using EMG signals has not been tested with real patient which has lost its hand, but only with healthy individual.


Easy to Reprogram

Our 3D printed Prosthetic Arm kits are based entirely on Arduino, it's code is very well supported. We work to post tutorials and explanations of the code on each of our kits. The Wide Arduino comunity also provides resources and tutorials on basic programming concepts. Additionally, since we use Arduino it can be programmed with graphic programming tools such as Scratch and Blockly, reducing the stress on new programmers to learn syntax.
