The objective of this research is to design and build a prosthesis printed of a hand which receives orders from a myoelectric signal that is located on the user arm. The design presented was generated by means of a 3D printer MakerBot Replicator+ looking for the costs of design and construction to be kept low, in turn to ensure the reliable development of the prototype, structural static analyses were generated for the SolidWorks software to the parts that they compose the same of which obtained results that give confidence to the design realized.Keywords: Static analysis, 3D printing, transradial prosthesis, Myoelectric system.
