To that end, Reed says Thornton Tomasetti is
developing predictive models to analyze the material and
mechanical properties of various 3D-printed components.
"Once the regulatory bodies come up with a way to
qualify and certify 3D-printed structures, there's no limit
to what we could see," says Reed.
A 3D-printing process was used to build a
metal pedestrian bridge, which will span
over a canal in Amsterdam.
INFINITE POTENTIAL
COURTESY OF MX3D
As bright as the future is, the technology offers a lot of
options for engineering firms today.
At the most basic level, engineering firms are using
3D printers to build scale prototypes of their designs to
impress a potential client. "We can demonstrate to the
client the possibilities and show them the advantages that
3D printing has to offer," says Reed.
The technology also allows firms to create designs and
use materials they would never have considered. "It's changed the
way we work," Reed says. "Previously, there was a finite list of materials that we could use, and the design had to conform to the limitations of those materials. With 3D printing, we no longer have those
limits."
3D printing also streamlines the production process. "It allows
us to go directly into fabrication," says Otani. "There's no misinterpretation of design documentation. For the Miami Design Festival
project, we went from digital models straight to the printer.
"There's almost no limitation with this technology, especially
when 3D printing is combined with full-scale robotics," he adds. "It
will significantly change how buildings are designed and how they
are built." ■
Holland, recently built a metal pedestrian bridge to span over a
canal in Amsterdam using an additive welding process. Two robots,
one on each side of the canal, created layer upon layer of spot welds,
gradually building the structure from each end until they met in the
middle. Arup performed several load tests to confirm the structural
integrity of the bridge.
REGULATORY LIMITATIONS
The 3D printing of structures has largely been an overseas
phenomenon, and that will likely continue because of U.S. building
codes.
"One of the challenges that we face the most is the qualification
and certification aspect of 3D printing," says Heather Reed,
associate in Thornton Tomasetti's Weidlinger Applied Science
practice. "It takes a long time to build up the necessary statistical
confidence."
