It is recommended to stop feeding and continue extruding until the extruder is fully empty, if the printing stops in a short term, such as 10-30 min.
It is recommended to stop feeding and continue extruding until the extruder is fully empty, then use polyethylene (PE) to clean the extruder, if the printing stop in a long term, such as several hours. It is helpful to avoid the carbonization of material and keep extruder working in a good condition

1：Definition of each concept
Layer time: the time spent for depositing one layer of the printed part.
Top layer temperature: the instantaneous temperature of a specific point on the topmost completed layer, measured when the nozzle printing the current layer is positioned directly above it.
Width: the cross-sectional dimension of the printed layer, perpendicular to the direction of the print nozzle's movement.
Height: the vertical dimension of the printed object, or the layer thickness during pellet printing.
Tr: room temperature when starting pellet printing.
2： The top layer temperature should range between the material's glass transition temperature (Tg) and its non-collapse printing temperature for optimal mechanical properties and dimensional stability.
3：Above data is inferred based on a melt temperature of 240°C at nozzle exit and a 1m*1m*1m square frame model.
4：The simulation condition is based on a closed room without additional air disturbances, and assumes some environment temperature increasement.
5：Above data is inferred based on the thermal history simulation software, Dragon, by Helio Additive. It should be used for reference only. For a more detailed analysis, please contact Polymaker.
