Light Weight ASA

This is colorFabb's most basic LW-ASA, no colorants added just the pure slightly off white ASA color. When foamed the surface finish is matte.

The LW-ASA material is capable of increasing its volume nearly 2.5 times. The filament density is close to 1.07 g/cm3 but when foamed at its maximum capacity users will achieve part density close to 0.43 g/cm3.

Like regular ASA the LW-ASA features inherent UV stability and high temperature resistance of 96C. Rest assured this material will be more capable of handling increased temperatures compared to our LW-PLA.

LW-ASA is more susceptible to warping compared to LW-PLA type filament. Especially models with a large footprint can shrink and warp during printing, but compared to ABS in most cases less severe.

Please note that color variations may occur. Color will turn lighter when material is at maximum foamed state as opposed to non-foamed state which shows a deeper and richer color.

Printing Advice

LW-ASA is more susceptible to warping compared to PLA or PETG type filaments. Especially models with a large footprint can shrink and warp during printing, but compared to ABS in most cases less severe.

Apart from using a large brim and heated buildplate of 90-100C (or higher if your machine is capable) we can also advice the following. Print a tall skirt around your model to reduce cold air flow around the printed model or print inside an enclosure for better control of the environment temperature.
