Material Characterization for 3D Printing Concrete
This work is part of larger research aimed at developing an algorithm to generate toolpaths that compensate for material deformation in the manufacturing of small-scale concrete parts — those in which interlayer time is less than the time interval until concrete stops deforming. Previous work determined the effect of the number of layers and beads on deformation and the time interval after which printed concrete stops deforming (t=34 sec).
This study investigates the effect of the number of layers and beads on layer width and layer height deformation as a function of extrusion rate and time before the time interval. The result is a model relating all the relevant variables that can be used to compensate for deformation in the toolpath design of small-scale printed concrete specimens.
