eSUN TPU-LW 3D Printing Filament Grey 1.75mm 0.75kg

• Disable retraction in the slicer software to prevent internal nozzle cavities that could cause clogging. Since lightweight TPU continues to foam inside the high-temperature nozzle chamber, retraction is ineffective. Stringing during idle moves is normal when printing, and you can use vase mode to reduce stringing effects on the model.
• Set the first layer speed to match the actual printing speed, at 100%. Disable the first layer and small-area slowdown function. Ensure the first layer extrusion rate matches the actual foaming extrusion rate (e.g., 58% at 260°C). If the adhesion to the build plate is too strong, adjust the bottom valve during printing.
• Pay attention to your printer’s maximum operating temperature. Most PTFE tube printers should not run above 250°C for extended periods, as this may cause clogs. For temperatures exceeding 250°C, use high-temperature machines with a metal hotend.
• Yellowing or nozzle sticking after high-temperature foaming is normal. Reducing the printing temperature can alleviate this issue.
• Tune the printer’s PID settings for stable temperature. Disable speed reduction, as large temperature shifts or speed changes can affect the foaming rate and lead to visible layer lines on the model surface.
• The foaming ratio is positively correlated with printing temperature—at a fixed printing speed, higher temperatures increase the foaming ratio, requiring a lower extrusion rate. Conversely, the foaming ratio is negatively correlated with printing speed—at a fixed temperature, higher printing speeds reduce the foaming ratio, requiring a higher extrusion rate. Adjust extrusion rate, temperature, and speed according to your specific printing conditions, and compare wall thickness in the model design to optimize settings.
