ePLA-LW Lightweight Filament 1.75mm 1Kg eSun

This is a filament specially developed by eSun for model airplane and drone construction. The filament is foamed at a higher pressure temperature, thus achieving a much smaller density than conventional PLA. At print temperatures below 210°C, it behaves very similar to PLA. At print temperatures of 210-270°C, the material begins to foam during printing, thus increasing its volume. The maximum volume is reached at about 270°C and corresponds to 220% of a normal PLA coil. The achieved density is therefore 0.54g/cm3. At the same time, the extrusion rate must be reduced. ESUN recommends approximately 45% at the maximum temperature of 260°C. If you print with 250°C, the extrusion rate must be 50% or factor 0.5 in order to achieve a volume of 200%.

Info: This is not a filament for beginners. We recommend you to handle these details with care and to adjust the print parameters yourself to your printer by experimenting.

Features of ePLA-LW:

Low density up to 0.54g/cm3 at 260°C print temperature
Volume ratio of up to 220% at 260°C print temperature.
Very good layer adhesion, the filament breaks into large pieces, making a broken wing easy to repair.
Very suitable for painting, the color adheres super to the print surface.
Excellent printability. No warping problem even with large models.

Tips for Printing with ePLA-LW:

Use the same print speed for all layers. Turn off the print speed reduction function to keep the foam ratio of all layers constant.
Beware of the print temperature. Most beginner printers start to clog when printing over 260°C for a long time. If you want to take full advantage of the maximum foam ratio, make sure your printer is designed for such temperatures.
It is normal for the filament to turn yellowish at very high temperatures. To prevent this effect, you can slightly lower the printing temperature, but you must accept a lower foam ratio in return.
The foam ratio depends on the print temperature, the print speed, the size of the melt chamber in the nozzle, room and print bed temperature, and humidity. Experiment with all these parameters to achieve your desired print conditions.
Increased stringing is normal with ePLA-LW. It is recommended to print in vases mode to reduce this as much as possible.
