Abstract:

The use of 3-D-printed tools with locally available polymers has the potential to increase efficiency and operational readiness on the battlefield. Currently, the US military has plastic 3-D-printing capabilities at the point of need, but only a limited choice of polymers. This effort summarizes the work of two Weapons and Materials Research Directorate-sponsored student projects and compares many different types of common 3-D-printable polymers to determine which one may be best suitable for the harsh conditions and austere environments associated with forward-operating bases. These polymers were subjected to mechanical and environmental testing for the purpose of characterizing and ranking. Post-fracture optical microscopy was undertaken to better understand the failure modes associated with each of the different polymers.
