## Summary description

Spectrum ASA LW UltraFoam is a lightweight, foaming 3D printing filament in traffic black. This 0.75kg refill spool is designed for advanced additive manufacturing, offering excellent UV resistance and thermal stability. Its foaming properties allow for density reduction during printing, making it ideal for creating lightweight, durable functional parts and prototypes with a matte finish.

## Long description

Spectrum ASA LW UltraFoam is a professional-grade 3D printing filament designed for advanced additive manufacturing. This lightweight, traffic black material utilizes active foaming technology to significantly reduce the weight of printed parts without sacrificing structural integrity. By leveraging the base properties of ASA, this filament provides exceptional UV resistance and thermal stability, making it an ideal choice for functional components that require durability in outdoor environments. The refill format offers a sustainable solution for high-volume users, ensuring high performance while minimizing plastic waste.
Advantages
The primary advantage of this filament is its ability to reduce the weight of printed objects by up to three times compared to standard materials. This is achieved through a controlled foaming process that activates at temperatures between 230°C and 285°C. Users gain precise control over the final density of their parts by adjusting the printing temperature and flow rate, allowing for a customized balance between weight and strength. Furthermore, the matte finish effectively masks layer lines, resulting in a professional aesthetic. The material also maintains the core benefits of ASA, including high weather resistance and dimensional stability, ensuring that parts remain reliable over time.
Suitable for
Lightweight drone and RC model components
Functional prototypes for outdoor use
Automotive parts requiring low weight
Large-scale models where material efficiency is critical
Technical housings and enclosures
When it may not be suitable
This filament is not recommended for applications requiring high-gloss surface finishes or extreme impact resistance, as the foamed structure is inherently more porous than solid ASA. It may also be challenging to use for beginners due to the requirement for precise calibration of temperature and flow settings to achieve optimal foaming results.
Key specifications
Material: ASA with active foaming technology
Density: Adjustable from approx. 0.33 g/cm³ to 1.08 g/cm³
Nozzle temperature: 220°C – 285°C
Heated bed temperature: 60°C – 90°C
Printing speed: 15 – 150 mm/s
Color: Traffic Black
Format: 0.75kg Refill (cardboard core)
How to use
To achieve the best results, start by printing a single-perimeter test cube in vase mode to determine the optimal expansion rate. Test temperatures in 5°C increments between 230°C and 285°C, keeping fan speeds low and print speeds slow. Once the temperature providing the maximum wall thickness is identified, perform calibration prints while gradually reducing the flow rate until the wall thickness matches your nozzle diameter. Always ensure the filament is thoroughly dried before use, as moisture can negatively impact the foaming process and surface quality.
What to consider before purchase
Requires a printer capable of reaching temperatures up to 285°C
Best results are achieved with enclosed-chamber 3D printers
Requires a reusable spool system, such as BambuLab spools or a printable master spool
Calibration of flow and temperature is necessary for every new project
Usage recommendations: For optimal performance, store the filament in a dry environment and use a filament dryer before printing. If the model adheres too strongly to the build plate, reduce the bed temperature or use a suitable release agent.
