📘 Lesson Content
🟩 1. What Is Construction 3D Printing?
Construction 3D printing includes multiple methods:
-
Layered extrusion: A nozzle extrudes cement or concrete paste in layers—no formwork needed
-
Binder jetting: Powder is fused by binder for modular components
-
Robotic slip-forming: Similar to 3D printing but in continuous flows youtube.com+9en.wikipedia.org+9cybe.eu+9facebook.com+4en.wikipedia.org+4cybe.eu+4youtube.com+3cybe.eu+3youtube.com+3
Advantages:
-
Reduced labor and formwork costs
-
Less material waste
-
Enables complex freeform designs
-
Faster project delivery en.wikipedia.org
Challenges:
-
