Advancements in 3D Printed Concrete

Mentor: Narayanan Neithalath
FURI: Fall 2018

This research will focus on the extrusion characterization of 3-D printable cementitious binders to optimize the printing process for on-site applications. A pressure cell setup was fabricated and used to determine the effect of nozzle size, volume, and mixture proportioning on the inlet/outlet pressure characteristics under ram extrusion. The extrusion pressure versus piston displacement results will be used to compare across different mixture designs to optimize the printing process for the desired output based on the material and geometry. The results will be used as guidelines toward further advancing the 3-D printing concrete technology.

3-D Printed Concrete

Mentor: Narayanan Neithalath
FURI: Spring 2018

The objective of this research is to advance the current state of 3-D printed concrete for its use to be industrialized in the future, for faster, cheaper and cleaner construction. During the Spring 2018 semester, successful prints have been made while focusing on the rheology parameters of the mix. To analyze the small-scale 3-D printed samples, scans were conducted to represent the prints as point clouds. Matlab was used to compare the actual prints to the CAD model through identifying the location of the defects. The next step is to develop a perfected printing process for the technology’s expansion.
