ePLA-LW (Lightweight PLA) is a material specially developed by eSUN for the fields of model aeroplanes, 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 aeroplanes, under the condition of balanced strength, reducing the weight as much as possible can greatly improve the performance of the aeroplane.
Product features:
- Low density, up to 0.54g/cm3
- The foaming volume ratio is 220%, and 1 roll of ePLA-LW is equivalent to 2.2 rolls of ordinary PLA
- Free adjustment of strength and foaming ratio
- The excellent surface effect, matte and delicate
- Good adhesion between layers, resistance to explosion and easy to repair
- Easy to paint, strong surface paint adhesion
- Excellent printability, large models do not warp, do not block, and do not need a constant temperature chamber

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.
