| Summary: | To strengthen 3D printed unmanned aerial vehicle parts, this paper aims to
investigate the feasibility of two post-processing techniques, namely heat treatment and protective
coating, with polylactic acid being the base material of comparison. For a higher degree of
crystallinity, the heat treatment is done at various temperature and duration above the glasstransition
point. Simultaneously, the protective coating strength of finishing and bonding type
epoxies are compared. The results indicate that heat treatment increases the elastic modulus but
also decreases the flexural strength. The scanning electron microscope images observed at the
filament level show the presence of cavities between and within layers after the heat treatment.
Protective coating increases the flexural strength and elastic modulus of the printed samples where
the bonding type epoxy performed better than the finishing type. |
