Hydrostatic Pressure Enhancement of AM Polymers

Boeing was interested in whether hydrostatic pressure-based post-processing could improve the mechanical properties of additively manufactured polymer parts, particularly for thermoset materials. This project focused on developing and assessing a materials treatment approach for up to five AM polymers, using hydrostatic pressure-based processes to examine their effect on the base material. The work assessed material changes through methods such as sectioning and density measurement to determine whether the treatment could improve material quality. This capability was intended to provide a clearer understanding of the potential benefits of pressure-based post-processing for AM polymers and to support validation and quantification of any resulting material improvements.
