I am designer and I have time free to work in development of your proyect, I can work with CAD design, analysis of prototypes, design of experimental tests protocol for you prototype, design in CAD software (Solid works or Inventor), calculation of stress and I can print the 3d model and sending (or the .Stl only) with PLA, ABS, carbon fiber, depending of use (to evaluate design, usability, ergonomy, etc). If you want integrated technology I can asesorate.
I can do investigation for new technologies, mathematics analysis, electronics components, integration of technology IoT, materials evaluation, patented shared and non-disclosure agreement.
I like innovated and thinking out of box.
The time can variated depends of prototype complexity, 3d print and evaluation of prototype.
