3D printing: first 3D-printed steel bridge to be built over Amsterdam canal

The video discusses a project in Amsterdam where robotic arms are used to construct a bridge over a canal. The project is set to start in September. A computer program designs the structure, and robotic arms weld metal at high temperatures, eliminating the need for scaffolding. The arms are supported by the structure they build, allowing them to 'walk' across the canal as the bridge is constructed.

When is the project to build a bridge over the Amsterdam canal scheduled to start?

• October

• August

• November

• September

What role does the computer program play in the bridge construction process?

• It designs the bridge.

• It provides weather forecasts.

• It supervises the workers.

• It transports materials.

To what temperature do the robotic arms heat the metal for welding?

• 1000 degrees Celsius

• 1200 degrees Celsius

• 1500 degrees Celsius

• 1800 degrees Celsius

What is one major benefit of the bridge construction technique described?

• It eliminates the need for scaffolding.

• It speeds up the construction process.

• It reduces the cost of materials.

• It requires fewer permits.

How do the robotic arms contribute to the construction of the bridge?

• They lay the foundation.

• They install lighting.

• They walk across the canal as the bridge is built.

• They paint the bridge.
