  • 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.
