In ‘ The Effect of Material Fresh Properties and Process Parameters on Buildability and Interlayer Adhesion of 3D Printed Concrete ,’ international authors strive to understand more about materials and parameters in relation to concrete—specifically in terms of buildability and inter-layer adhesion properties.

3D printing with concrete is being used by companies and researchers around the globe today as they hope to harness all the classic benefits of 3D printing, from affordability to greater speed in production, and the ability to create more complex geometries—often meaning that products and prototypes not possible before can now be fabricated. And although there is a growing sense of acceptance of the technology, the researchers explain that there is still little data regarding materials and process parameters. “A soft, flowable material is easy to extrude,” explained the researchers. “On the other hand, a stiff material can sustain the weight of more layers, although […]
