SainSmart Lightweight LW-PLA Filament

SainSmart Lightweight LW-PLA Filament

SainSmart LW-PLA Filament Overview

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.

The expanding property of this PLA Filament allows for excellent layer bonding, better drop resistance, and repairability. In combination with the low-density feature, this filament is a perfect option for RC planes, drone parts, and cosplay models.

Features

Light Weight Feature of SainSmart LW-PLA Filament

Light Weight

With active foaming technology, this LW-PLA filament delivers low-density and lightweight parts. The SainSmart LW PLA Filament has a density of 0.54 g/cm³, resulting in a significant weight reduction for your printed parts, perfect for RC planes and drones. The reduced weight enables lower wing loads and stall speed, allowing for overall better performance.

Active Foaming Feature of SainSmart LW-PLA Filament

Active Foaming

The foaming expansion of this LW PLA filament allows you to print with up to 2X material flow. The maximum foaming rate of this LW-PLA filament is 220%, meaning that one roll of LW-PLA can be used as 2.2 rolls of ordinary PLA. This allows you to print more with less material.

Smooth Finish Feature of SainSmart LW-PLA Filament

Smooth Finish

Models printed with this LW PLA filament have a smooth matte surface with minimal layer lines. The improved paint adhesion also enhances your creativity. The foaming feature allows for almost invisible layer lines and a smooth matte finish.

Customizable Expansion Effects

The LW PLA filament will start expanding at certain printing temperatures above 210℃. By adjusting the printing temperature, speed, and flow during your print, you can customize the expansion effect for different densities in various sections of a model.

LW-PLA has stable interlayer bonding, and the expansion rate, density, and strength can be controlled by adjusting the printing temperature.
