LW-PLA UltraFoam
Active Foaming Tech | 65% Weight Reduction | 0.75kg
Spectrum LW-PLA UltraFoam is a revolutionary material designed for applications where every gram counts. Utilizing Active Foaming Technology, this filament triggers a controlled expansion when heated above 230°C. By increasing the volume and reducing the density, you can print parts that are up to 3 times lighter than standard PLA without sacrificing structural integrity.
The Dark Grey finish offers a sleek, industrial look reminiscent of stealth aircraft composites. Beyond weight saving, the foaming process creates a unique matte surface finish that effectively hides layer lines and provides superior sandability for post-processing.
By controlling the printing temperature, you can vary the expansion rate. At higher temperatures, the material foams more, allowing you to use reduced flow rates (down to 35-40%) to achieve the same volume with significantly less mass. It’s the ultimate tool for RC pilots and aeronautical engineers.
⚖️ Ultra-Low Density
Achieve a density as low as 0.40 - 0.50 g/cm³, allowing for longer flight times and better lift-to-weight ratios.
🛡️ Superior Layer Bonding
The foaming action creates a robust internal structure, ensuring excellent adhesion between layers even at high speeds.
🏗️ Matte Stealth Finish
A non-reflective, professional dark grey surface that diffuses light and masks the 3D printing "stepped" look.
🔨 Post-Process Ready
The foamed surface is incredibly easy to sand, prime, and paint compared to standard rigid plastics.
- Fixed-wing RC aircraft and drone frames
- Aeronautical prototypes and wing sections
- Internal thermal insulation components
- Lightweight cosplay props and large-scale helmets
- Acoustic dampening and protective housings
- Floating maritime models and water-stable parts

Optimize your flight weight with precise technical data:
* Engineer's Tip: When using the foaming feature, print a single-wall calibration cube to find the perfect Temperature vs. Flow balance for your specific nozzle. Note that foaming slightly increases stringing, so "Outer Wall First" printing is recommended for the cleanest surface finish.
