Robots Transform 3D Printing

A new technology called MX3D will take 3D printing to a new level of sophistication and complexity by using multi-axis industrial robots to “draw” metal structures in mid-air. The new platform will allow virtually unlimited freedom of design for large-scale, functional structures.

The first project (which is set for completion in 2017) will be a pedestrian bridge to be printed in place by robotic arms at a location in Amsterdam that is, as yet, undisclosed. The robots will work their way from one side to the other, using the load-bearing structure to support their own weight as they progress.

Using a technique that can best be described as a combination of resin printing and welding, strands of molten metal are created in vertical, horizontal or spiraling lines as the robot arms rotate along six different planes of motion. Software controls the pulse-time, pause time, layer height and tool orientation for a variety of metals including steel, stainless steel, aluminum, copper and bronze. Compared to existing 3D printing methods, MX3D is more cost effective and scalable, and will offer a broader range of creativity for architecture, industrial design and art.
