Robust aka oversized does not counter brittle fracture, though, which is the main concern with 3D-printed artifacts. It depends on the material / the alloy but also on the technological process we generally call printing.
- Robotbeat 8y agoIt actually does, since it reduces the local stress. Risk of fracture due to defects and repetitive loading is dramatically reduced (by order of magnitude or more) by increasing the material margins. It's a short foot bridge, so it's pretty easy to design it with significant enough margin. That said, it's not a very good idea nor a scalable solution to, like, anything. More like an art project.
- DrNuke 8y agoYes, you are basically saying that this particular artifact is just like a bridge-shaped pancake made of polystyrene and hosting very few ants at any given time. Which is actually an art project.
- Robotbeat 8y agoI think that's overstating it. This bridge is plenty strong, just very inefficient and expensive.
- geezerjay 8y ago> Risk of fracture due to defects and repetitive loading is dramatically reduced In this case I believe the design is due to concerns regarding the additive manufacturing process, which is prone to introduce a lot more defects than standard steel sections, and ina way that are hard to spot and to track.
