eSun e PLA-LW Lightweight PLA Filament Natural 1.75mm
Specification:
Filament diameter: 1.75mm ( +/- 0.05mm) Color: Natural
Features:
ePLA-LW (Lightweight PLA) is a material specially developed by eSUN
for the fields of model airplanes, drones, and COSPLAY. Compared with
WOOD, ePLA-LW has more stable interlayer bonding, and the foaming rate
and strength can be controlled by adjusting the printing temperature.
Use active foaming technology to achieve lightweight, low-density PLA
parts. The foaming volume ratio is 220%, and when printing the same
volume model, 1 roll of ePLA-LW can be used as 2.2 rolls of ordinary
PLA. Foaming makes the layered pattern almost invisible, and the surface
of the printed item is matte and delicate. At around 210-270°C, this
material starts to foam during printing, increasing its volume by nearly
1.2 times, and the printing extrusion rate can be reduced to 45% to
print lightweight parts.
Under the same model and at the same speed, the use of lightweight
PLA enables the model aircraft to have a lighter wing load and a lower
stall speed. For models such as airplanes, under the condition of
balanced strength, reducing the weight as much as possible can greatly
improve the performance of the airplane.

Precautions:
1. Note that the first layer speed setting is consistent with the
actual printing speed, set to 100% of the actual printing speed, turn
off the first layer and small area printing speed reduction function,
the first layer extrusion rate is consistent with the actual foaming
extrusion rate, such as 270 degrees set to 45% of the first layer
extrusion rate; if the bed adhesion is too strong, you can set the
bottom valve when printing.
2. Pay attention to the maximum operating temperature of the printer.
Most Teflon tube printers cannot be operated for a long time above
250℃. Long-term printing above this temperature may cause blocking. If
the temperature exceeds 250℃, high temperature printers such as metal
hoses are required for printing.
3. Yellowing of printed parts after high temperature foaming is a
normal phenomenon. Lowering the printing temperature can relieve it.
4. Since the ePLA-LW foams continuously in the melting cavity of the
high-temperature nozzle, the retraction basically does not work.
Stringing is normal during printing. It is recommended to print the rc
plane in vase mode to reduce the effect of stringing.
5. Foaming ratio is related to temperature, printing speed, nozzle
melting cavity size, pay attention to compare model design wall
thickness according to your own printing situation, adjust extrusion
rate, temperature, speed and other parameters.Do you need help? Do you have any questions?Ask a question and we'll respond promptly, publishing the most interesting questions and answers for others.
