A single design rule doesn’t apply to all 3D printing technologies. Technologies like FDM and SLA utilise support structures while others don’t. Engineering features like wall thickness, holes and tolerance limits should also be designed differently for different technologies.
Designing for 3D printing is not a tough task as long as you know the rules. They help in improving the efficiency of printing as well as reducing costs. Xometry Europe offers 7 different types of additive manufacturing processes and this guide provides an overview of design rules with respect to each 3D printing technology.
