A word of warning here is about the FDM printing method. As the filament needs to be molten to be deposited on the 3D printing bed, it is heated, depending on the material, at more than 180°C in the 3D printer hot-end. This also means that every compound and material you have incorporated into the plastic will also be subjected to high temperatures, even if for a short amount of time. This high temperature may be detrimental, especially to organic molecules, and it should be considered when printing these composite materials. A way to monitor the degradation of organic molecules during the printing process is to dissolve the material after the 3D printing process and re-characterize the organic compounds using NMR, MS, and UV-Vis.
