Cementless Concrete 3D Printing (Geopolymer) – AC3D Innovation
At AC3D, we’re pioneering sustainable construction through 3D printing with cementless geopolymer concrete. Our innovative material blend eliminates traditional cement, significantly reducing CO₂ emissions while maintaining the structural strength and durability required for on-site and off-site construction applications.
What Is Geopolymer Concrete?
Unlike conventional cement-based mixes, geopolymer concrete uses industrial by-products like fly ash or slag, activated with alkaline binders. This eco-friendly alternative offers:
-
Up to 80% lower carbon emissions
-
High chemical and fire resistance
-
Excellent early and long-term compressive strength
-
Compatibility with on-site 3D printing extrusion systems
How We Use It in 3D Printing
Our Codemason series printers (2.0, Micro Factory, are calibrated for geopolymer extrusion)
We can print walls, structural panels, benches, and more using geopolymer reinforced with rebar or fibers for added strength.
Benefits of Using Cementless Geopolymer in 3D Printing
| Benefit | Description |
