Increasing temperature produced a greater crosslink density
in sensitized PLA, while TMPTA exhibits auto-polymerization
tendencies at elevated temperatures. All PLA samples showed
an increase in crosslink density as temperature was increased,
with temperature having a greater effect on lower irradiated
samples. We demonstrated materials that could be 3-D printed
and later crosslinked into thermosets and that increasing temperature
can effectively be used to improve crosslink density in
sensitized PLA, a 3-D printable polymer. We hope this will enable
a host of new devices and materials in the coming advanced
manufacturing age.
