2.3 Annealing Treatment
It is recommended that the engineering filaments should be annealed after finishing
printing to eliminate the internal stress of the model, improve the properties of the model
and slow down the second-time moisture absorption of the model. Place the filament in
the filament drying station, enable the drying function and set the corresponding
temperature and time, thus the annealing treatment is carried out.
Annealing treatment is recommended for the following materials:
PA, PAHT and PA12-CF should be annealed to improve the mechanical properties of the
model samples.
Annealing conditions:
PA：
Place the sample in the Filament Drying Station at 70℃ and dry it for 2 hours.
PAHT： Place the sample in the Filament Drying Station at 70℃ and dry it for 2 hours.
PA12-CF： Place the sample in the Filament Drying Station at 80℃ and dry it for 6 hours.
