Efficiencies in design, construction and building use are being unlocked thanks to analysis and proactive changes informed by construction data. Even 3D printing for a NASA project on structures on Mars is on the table.

A construction tech company that printed the walls of a 350-sq-ft “tiny house” in 48 hours in Austin, Texas, in March is now partnered with a nonprofit that aims to start printing walls for 800-sq-ft homes in El Salvador—in 24 hours for each—by the end of the year.

A standard, industrial robotic arm has “printed” about a third of a 12-meter pedestrian bridge that is destined to span an old Amsterdam canal in the Netherlands as early as next year.

When Caterpillar began its current investment in 3D-printing components for heavy equipment earlier this decade, the company’s engineers and chemists tried to manage their expectations.

The nascent 3D-printing industry is working toward the goal of printing large-scale structures with specially designed feed material, but researchers working at a smaller scale are currently exploring techniques for printing a wide range of materials in complex shapes.

NASA’s challenge to adapt additive manufacturing for robots on Mars is only one sign 3D printing is becoming a reality in construction
