MX3D is to 3D-print a steel bridge over water in Amsterdam 12 hours ago by Nancy Owano weblog Please Register or Log in to view the hidden image! MX3D is an R&D startup focused on 3D-printing metals and resin in mid-air, without the need for support structures. They pride themselves in "robotic technology with which we can 3D print beautiful, functional objects in almost any form." Now they say "We are going to print a steel bridge in Amsterdam." The robots will be printing in steel and the robots will print that bridge over water in Amsterdam. The project team sees the metal bridge as serving as a showcase for present-day capabilities in software, engineering and design.

The process is just like welding but with a robot arm. The steel might have flux mixed in so it welds to itself.
Such a structure might be made even stronger and 100X faster in space where vacuum welding techniques work even better. The Starship Enterprise was 5D holographically printed along with most of Star Fleet at Utopia Planetia, wasn't it? MultiThink BIG.
