3D-printed structures behave very differently compared to your usual, continuous materials which are bolted, jointed or welded together, in that re-balancing loads and reactions. Another issue is how they cope with aggressive environments. This is a real-life experiment, something someone would however do, so let’s what happens. I’m confident they will be fine, we are even having 3D printed components for nuclear power plants already.

- rtkwe 8y agoAnd a weld executed properly with the same filler material acts more or less like a single piece of metal (minus any issues with the local heating of the pieces.
- haggy 8y agoDo you have experience with 3D printing? I have pretty extensive experience with 3D printing plastics and I can assure you that it's nothing like plastic weld. How is 3D printed steel like a contiguous weld?
- Robotbeat 8y agoThey literally use a welding machine on a robot arm, that's how. Powder bed metal 3D printing is different, however. (And I would argue that FDM is essentially plastic welding, too.)
