PLA-LW Filament

Overview

PLA-LW (Light Weight PLA) is a filament specially developed for aeromodelling. It uses active foaming technology to achieve lightweight, low-density PLA parts with a foaming volume ratio of 220% and a density as low as 0.54 g/cm³. The interlayer bonding is stable, and both foaming rate and strength can be controlled by adjusting the printing temperature.

Key Features

• Foaming makes layered patterns almost invisible

• Matte and delicate surface finish

• Enables lighter wing load and lower stall speed for model aircraft

• Greatly improves aeromodelling performance
