Filament Spectrum LW-PLA UltraFoam 1.75mm PURE WHITE 0.75kg

Product detailed description

Spectrum LW-PLA UltraFoam is an innovative filament that combines the properties of high-quality PLA with advanced active foaming technology. Thanks to its unique material properties, it enables a more than 3-fold reduction in the weight of printed parts without compromising strength or surface quality. LW-PLA UltraFoam is the ideal solution for anyone looking for lightweight, durable and aesthetically pleasing prints, especially where weight is critical – for example, in model making, drone construction or prototyping.

The filament is based on the proven Spectrum Premium PLA and is enriched with components that allow for controlled volume expansion during printing. The foaming process is activated at a temperature of around 220 °C, with maximum effect achieved in the range of 240 °C–250 °C. When printing below 220 °C, the material behaves like standard Premium PLA, offering great flexibility in choosing print settings.

In the full foaming phase, the filament expands more than 3x and reaches an extremely low density of around 0.40 g/cm3. LW-PLA UltraFoam provides significant flexibility in flow settings, allowing for a reduction of up to 70%. The level and speed of foaming can be regulated using temperature, allowing the density to be adapted to specific parts. The foaming capability also helps speed up 3D printing by using thicker layers or single, solid perimeters. With LW-PLA UltraFoam, you can achieve prints weighing only about 30% compared to standard PLA – more than 3x lighter while maintaining durability and aesthetics.

The matte surface effectively hides layer lines and gives printed parts a professional appearance. The degree of foaming also affects the shade – with greater expansion, the colour may appear significantly lighter. Furthermore, the filament retains all the key properties of classic PLA – ease of printing and stability. It is the perfect solution for applications where every gram counts, such as RC modelling, drone construction or lightweight functional components.
