Effect of Hydrogen and Vapor Solvent Exposure on the Mechanical Properties of 3D Printed Polylactic Acid
Faculty Sponsor
Patrick Ferro, Gonzaga University
Research Project Abstract
Polylactic acid (PLA) test specimens were printed at two different infill percentages and for two different infill hatch geometries. Specimens were exposed to gaseous hydrogen and tested in tension and in relaxation. The objective of the work is to determine the effects of infill geometry on the mechanical properties of 3D printed PLA as a surrogate for rapid prototyped organs. Speed to print is affected by infill geometry and percentage, so optimizing printed organ life is a function of each of these parameters. Further investigation will replicate the tests following exposure to vapor solvents including that from exposure to methanol.
