Data for article: "Interlayer bonding has bulk-material strength in extrusion additive manufacturing: new understanding of anisotropy "

These are the gcode files for the reference specimen in F and Z directions in the article titled "Interlayer bonding has bulk-material strength in extrusion additive manufacturing: new understanding of anisotropy" in the journal Additive Manufacturing. The files should be used for reference only and not used on a 3D printer because all 3D printers use slightly different GCODE formatting and running an incorrect GCODE file could lead to damage to the printer.
