Other Comments
* 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 ## Recommended Printing Parameters

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 230°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.
