Circular diagrams of change in the FDM part area during 1 h exposure to organic and inorganic solvents. (
) the material collapses during the experiment (ΔS > 20%): the object loses its shape by dissolution, disintegration and/or delamination; (
) the material shows moderate stability during the experiment (ΔS = 2–20%), with minor swelling or dissolution of the outer layers, but satisfactory retention of the shape; (
) the material is stable during the experiment (ΔS < 2%): the object retains its shape, and no dissolution of the outer layers is observed (see Supplementary Movie S3). 1Destruction of Primalloy in THF took just a few seconds.
