Hi there,
This is Bogdan from Romania.
I'm a mechanical engineer - specialized in the industrial robotic field, 3D designer and modeler (from time to time and some projects I could make the functional prototype too).
I'm doing product design, industrial design, reverse engineering, ideation, etc.
I have over 15 years experience working on various systems/devices across multiple industries, from concept to launch.
1 - what kind of ladder do you need? folding, extensible, fragmented, with platform?...
2 - do you have any drawing/sketches of this new ladder?
3 - what materials to be used?
4 - the output files will be for prototyping as you requested... in any of the common cad formats (iges, step, sat, stl, dxf/dwg, 3d pdf)
5 - what simulation?... this requirement make me think that is an articulated/foldable type of ladder...
btw - the price will be adjusted accordingly with the complexity of the project
Regards
Bogdan
