About this item

[Reduced Weight]: Designed with active foaming technology, the SainSmart LW PLA Filament density of 0.54g/cm compared to 1.2 g/cm for regular PLA, means a huge weight reduction to your printed parts, perfect for stuff like RC planes and drones. The reduced weight enables lower wing loads and stall speed, allowing for overall better performance.

[2X 3D Prints with One Spool]: The foaming expansion of this LW PLA filament makes it possible for you to print at up to 2X Material flow so that you can print more with less material. One LW PLA roll equals up to 2.2 ordinary PLA rolls.

[Unlimited Customization]: The LW PLA filament will start expanding with certain printing temperatures above 210 ℃. By adjusting the printing temperature, speed, and flow during your print, you can customize the expansion effect by using different temperatures and speeds in a section on a model for varied density.

[Smooth Finish & Paint Friendly]: Models printed with this LW PLA filament has a smooth matte surface with minimum layer lines. The improved paint adhesion also sets no limit on your creativity.

[Perfect Materials for RC Planes]: The expanding property of this PLA Filament allows for excellent layer bonding, better drop resistance and repairability. In combination with the low-density feature, making this filament a perfect option for RC Planes and Drones Parts, Cosplay Models.

SainSmart LW-PLA (Lightweight PLA) is a 3d printing material specially developed for aeromodelling drones and cosplay. Compared with regular PLA Filament, printing with the LW-PLA Filament delivers a lighter wing load and a lower stall speed to your aircraft models. With a better balance between strength and weight, it also brings better performance to your models.

This material starts to foam and expand when printing above 210 ℃, the prints volume can increase by nearly 1.2 times, the printing extrusion rate can be reduced to max of 45% to print lightweight parts.

Printing Tips:

• The initial layer print speed and extrusion rate should be the same as print speed and extrusion rate settings, changes in print speed will also change the expansion rate of this material and cause layer lines. If the prints stick too firm to the build plate and unable to remove. please consider adding a raft.

• Pay attention to the maximum operating temperature of your 3d printer, most 3d printers with Teflon Heatbreak tube cannot run above 250 ℃ for a long time, or melting and blockage may occur. If you need to print above 250 ℃ constantly, we recommend you use high-temp Full Metal Hotend 3d printer.

• It is normal for Highly expanded prints to yellow. To reduce this effect, reduce expansion and print at lower temps.

• LW-PLA will continue to foam in the melt zone of the nozzle, so retraction does not work in this circumstance, and your 3d printer will continue to print even when the extruder crosses an empty space and cause stringing. We recommend you print in vase mode.

• Printing temperature, speed, and nozzle melt zone size will all affect the foaming ratio, so you need to adjust the wall thickness, extrusion rate, temperature, speed, and other settings according to your models and printers.
