LW-ASA
This is the most basic version of LW-ASA, with no added dyes: just the natural color of ASA, slightly off-white. Once expanded, the surface finish becomes matte.
The LW-ASA material is capable of increasing its volume up to about 2.5 times. The density of the filament is about 1.07 g/cm³, but when expanded to maximum capacity a part density around 0.43 g/cm³ can be achieved.
Like traditional ASA, LW-ASA offers high UV stability and a heat resistance of 96°C. You can be sure that this material will withstand high temperatures better than our LW-PLA.
LW-ASA is more prone to warping than LW-PLA filaments. In particular, patterns with a large surface area may shrink and warp during printing, although usually to a lesser extent than ABS.
Note that color variations may occur: when the material is in its maximum expansion, the color tends to be lighter than in its unexpanded state, where it appears deeper and more intense.
In addition to using a large brim and a top heated to 90-100°C (or higher, if your machine allows it), we can also recommend the following: print a high skirt around the model to reduce the flow of cold air around the print, or print inside an enclosure for better environmental temperature control.
Specifications
- Material: colorFabb - LW-ASA
- Diameter tolerance: ± 0.1 mm
- Density: 1.07 g/cm³ (unfoamed) - 0.43 g/cm³ (foamed, printed at 40% flow rate)
