colorFabb LW ASA

This is our most basic LW-ASA, no colourants added either Black or Natural. When foamed the surface finish is matte.

The LW-ASA material is capable of increasing its volume nearly 2,5 times. Meaning parts can be printed with reduced flowrate down to 40%. The filament density is close to 1,07 g/cm3 but when foamed at its maximum capacity and printed at 40% flowrate 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.

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.
