Representation of stability test of FDM parts in liquid media. (a) PLA parts made by standard extruding technology; (b) PLA parts made in this work by FDM 3D printing; (c) macrophotos of the extruded part (left) and FDM printed part (right) with same diameter 2.85 mm; (d,e) snapshots of the chemical resistance tests in DCM for the 3D-printed part (extrusion multiplier k = 0.9) and for the extruded part, respectively, with a brass cylinder as an indicator of integrity (Supplementary Movies S1, S2); (f) the principle of FDM-based additive manufacturing; (g) layered structure produced by FDM, (h) destruction of the 3D-printed surface due to interaction with a solvent.
