| Abstract Scope |
Large-format additive manufacturing (LFAM) is a manufacturing technique where a high volume of material is extruded in a layer-by-layer fashion to form structures that typically measure several meters in scale. Loci Robotics, Inc.’s LOCI-One system is an LFAM-type system that features a high throughput extruder mounted on a 6-axis robot arm. This research used the LOCI-One system to print single bead walls of 20% by weight carbon fiber reinforced acrylonitrile butadiene styrene (CF-ABS) at various print speed control, layer times, and bead widths. Thermomechanical performance of the CF-ABS walls was measured to quantify effects of print parameters on the z-strength, modulus, and coefficient of thermal expansion (CTE). Mechanical properties were measured using flexural testing. The CTE of the LFAM printed walls was measured using a large-scale digital image correlation system to characterize the distortion of the fiber reinforced composite material in the x- (print direction) and z- (between layers) directions. |
