What is 3D Concrete Printing?
3DCP refers to the process used to synthesize a 3D model in successive layers of material to create an object, e.g. a concrete wall

3DCP projects and applications over the past 20 years….
How does it relate to Circular Economy?
3DCP has the potential to enable the mass production of
▪ functionally-graded materials,
▪ elements designed for dissasembly,
▪ multi-material building components, and
▪ optimised structures with low-embodied energy…
… in a more sustainable and cost-efficient manner vs. current methods.

Technological challenges:
Non-technological barriers:
▪ True design-to-fabrication framework
▪ Increase reliability and robustness
▪ Reinforcement strategies
▪ Building standards
▪ Market acceptance
