Not long after putting together some basic sections for the 3d printed segments, I realized that the cost to manufacture sections equivalent to the 1” aluminum framing in shear was unreasonably expensive. So its back to the design board again. Realistically, most failures occur in bending so my next route will likely be a hollow section with shear reinforcement at attach points. While putting together the sections I generated a setup with 4 fastener locations at the ends of the sections which I plan to carry forward into the next design iteration. I will likely also remove the ability to slot fastening into the channels since this would result in variable locations requiring shear reinforcement. Obviously I can engineer for actual loading scenarios which would make most of these considerations moot. But, presently I’m trying to find a versatile setup that is economical and efficient for load management.
