The most heard criticism on this phase is that 3D printed materials are not stable to organic solvents compared to commercial laboratory plastic parts. Do not get me wrong; this is a valid criticism, and it is true. The most common 3D printed plastics, polylactic acid (PLA) and polyethylene terephthalate glycol (PETG), are dissolvable in chlorinated solvents. At the same time, acronytrile butadiene styrene (ABS) is soluble in acetone, which would make these materials not suitable for a laboratory environment. However, I argue that these materials are splash-resistant. They will not magically disappear if one drop of solvent touches them. If you repeatedly flood your fumehood with organic solvents, I suggest revisiting the safety procedures of the laboratory for handling chemicals rather than buying chemical-resistant holders. This boils down to rephrasing an ancient Sun Tzu quote: "know your 3D printer, know your material, and you will never be defeated".
