LW-ASA (Light Weight ASA)
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.
After printing the LW-ASA Black will turn slightly lighter shade of black. When foamed the surface finish will also turn matte, which gives a very professional looking result. Due to higher temperature resistance of LW-ASA you don’t need to worry about heat absorption.
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.

To reduce warping we would advice to use the least amount of cooling possible. Also for best mechanical performance try printing with the least amount of cooling needed, for optimal layer adhesion.
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.
