This paper describes the design process of a bicycle truss for metal additive manufacturing. Efficient truss structure allows hooking truss rod elements into 3D printed joints. The most undesired byproduct feature of metallic 3D print is
the support structures that require tedious labor to remove it. The paper shows conceptual design of joints such that supports would be entirely eliminated, while maintaining reliable and weight optimized truss joints. The conceptual design is fully demonstrated on one of the most known truss structures - the bicycle frame. The paper illustrates the design concepts evolution as well as
emphasizing the prototyping stage, where the CAD designed parts were first printed in low cost plastic 3D printer.This enables a preliminary inspection of
the parts fit and the compatibility of the frame with the other bicycle peripheral parts, before manufacturing by the metal printer.
