Description
Christopher Bock and colleagues map how printing settings shape large 3D-printed carbon-filled plastic in a 2026 study. Eight setting combinations varied layer thickness, print speed, bead gap, and screw rate. Forty-five microstructure samples and nearly one hundred eighty bending samples linked process to internal structure and strength.
Stiffness along the printed bead far exceeded stiffness between layers, confirming strong direction dependence. Screw speed steered fiber alignment, and alignment steered strength and stiffness in turn. High-speed photography and fracture surface microscopy added failure detail at the moment of breaking. Large-format printing serves boats, vehicles, and buildings, where such gaps matter structurally. Designers gain a reference dataset for validating models that predict properties from settings. Choosing settings blindly, the data show, can halve the strength a part actually delivers.
