What It Means

Additive manufacturing is the process of creating physical objects directly from digital models by building them layer by layer. Also known as 3D printing, it’s used in construction to form walls, components, or entire structures using materials like concrete or polymers.

Why It Matters

This technology offers unmatched design flexibility and efficiency. It reduces material waste, speeds up construction, and makes it possible to produce complex or custom geometries that would be difficult or expensive with traditional methods. Test materials for strength and consistency before use.

Best Practices

• Use for geometrically complex or repetitive components
• Pair with BIM or CAD tools for smooth digital-to-physical workflows.
• Consider post-processing (e.g., curing, reinforcement) for structural applications.
  
  

Real-World Use

Construction teams have successfully used additive manufacturing to 3D-print small homes, bridges, and façade components. One example is on-site printing of affordable housing units in developing regions, drastically cutting build times and labor needs.

In Simple Terms

Imagine a machine that “prints” a house instead of assembling it brick by brick. No cutting, no molds—just one smooth, continuous build. That’s additive manufacturing.
