ColorFabb Black LW-ASA Filament - 1.75mm (0.65kg)

ColorFabb LW-ASA utilizes active foaming technology to achieve lightweight, low-density ASA parts. At 240°C LW-ASA will begin to foam and expand — this unique property allows users to experiment and fine-tune their print settings to achieve different results. Depending on flow rate, this material is capable of increasing its volume by nearly 2.5 times, meaning that parts can be printed with a reduced flow rate down to 40%.
Similar to regular ASA, LW-ASA features the same inherent UV stability and high-temperature resistance.

EXPAND YOUR PRINTING HORIZONS WITH COLORFABB LW-ASA

The key to mastering LW-ASA lies in understanding the effect exposure to heat has on its expansion properties. At 240°C LW-ASA will begin to foam and expand, by experimenting with decreasing the flow rate – that is increasing the amount of time it takes the filament to pass through the hot end and nozzle – the more this material will expand.

Experimenting with print settings such as temperature, flow rate, and speed will be required in order to fully take advantage of the expanding properties of LW-ASA.

APPLICATIONS:

ColorFabb’s LW-ASA can be used in a multitude of different applications; however, the most common use cases for this material is to either achieve lightweight printed parts or to rapidly prototype models by increasing layer heights.

Lightweight printing can be achieved at temperatures between  240° - 260°C, Flow speeds as low as 40%, and print speeds no faster than 50mm/s. When experimenting with these settings it is important to keep in mind that due to decreased flow rate the hotend may become prone to clogging as a result of material expansion.
