3D-printed acrylonitrile butadiene styrene (ABS) polymer structures were coated with alumina (Al2O3) using the trimethylaluminum(III) and water atomic layer deposition (ALD) process at 80 °C, which resulted in a 203 nm thin film with a 1.35 Å growth per cycle. This thin film was a well-adhered protective overcoating on ABS to prevent reaction with acetone vapors in a solvent resistance experiment. Scratch tests were not able to remove the overcoating from the polymer surface, which provided a 50% and 32% increase in acetone vapor resistance before initial deformation and complete structure collapse, respectively. A more aggressive tape test caused delamination of the protective coating. This proof-of-concept experiment demonstrates how 3D printing combined with ALD overcoating can alter the chemical characteristics of complex polymer architectures.
