Description: We need your insight to help us create a better support for the flexible design methodology of DDM vehicles. The construction should be modular even at a large scale. For our first prototypes, we have a front steering module, a center occupant module and a rear power module. We need a fastening methodology to connect these very large modules together so that they will perform under heavy driving as well as crash situations.
Challenges to Overcome:
1. Fastening points will see forces from many directions so the overall solution will have to handle all the potential force vectors that would occur between modules.
2. As always, assembly should be minimal, precise and repeatable. This means that the use of both chemical and mechanical fasteners should be implemented using a method that is not labor intensive, and either minimizes variability of the execution or ensure performance is not impacted by the variability.
3. Our current printing capability is still only 3 axis for the moment, so fastening methodologies should be conscious of the impact of the printing vector of the parts that will have mechanical connections.
Please provide your suggested general process approaches to join large printed bodies. We don’t need all the models and assets created; we simply need your suggested approach. Please include the following:
o A general description of the mechanism and approach
o A short description of hurdles addressed
o Links to any supporting info
o Essential links or leads to any specialized materials, hardware or equipment for the solution
o Simple diagrams to illustrate the connection method
