SainSmart LW-PLA Filament – Lightweight Active Foaming PLA, 1.75mm, 1kg (2.2 lb), Black or White

Overview

The LW-PLA (Lightweight PLA) Filament is a specialized active-foaming 3D printing material engineered for applications where minimizing weight is critical without sacrificing strength. Developed specifically for RC aircraft, drones, aeromodeling, cosplay props, and lightweight structural components, LW-PLA uses advanced foaming technology to create low-density parts that are significantly lighter than standard PLA prints.

With a density as low as 0.54 g/cm³ and a maximum foaming rate of 220%, LW-PLA allows users to print larger, lighter components while consuming less material. The active foaming process also improves layer adhesion, impact resistance, and surface finish, making it an excellent choice for performance-focused projects.

Lightweight Performance

LW-PLA is specifically engineered to reduce the overall weight of printed parts.

Benefits include:

• Lower wing loading for RC aircraft

• Reduced stall speed

• Improved flight performance

• Lighter drone components

• Reduced material consumption

• Easier handling of large models

Its low-density formulation helps achieve an optimal balance between strength and weight.

Active Foaming Technology

Unlike conventional PLA, LW-PLA expands during printing when exposed to higher temperatures.

Advantages include:

• Up to 220% expansion rate

• Reduced filament usage

• Increased print volume per spool

• Lower overall part weight

• Enhanced structural efficiency

• Improved material economy

One spool of LW-PLA can produce a volume equivalent to approximately 2.2 spools of standard PLA under optimal foaming conditions.

Smooth Matte Surface Finish

The foaming process naturally minimizes visible layer lines.

Benefits include:

• Smooth surface appearance

• Reduced post-processing

• Improved paint adhesion

• Professional-looking finished parts

• Enhanced cosmetic quality

• Better presentation for cosplay and display models

Adjustable Expansion Control

The expansion characteristics of LW-PLA can be customized during printing.

By adjusting:

• Nozzle temperature

• Print speed

• Flow rate

Users can control:

• Density

• Weight

• Strength

• Surface finish

• Expansion rate

This allows different sections of a model to be optimized for specific performance requirements.
