If your filament is already wet, then you can dry it out with an oven set at around 60 ☌. This should preserve the filament and prevent it from absorbing too much moisture. Stringing and fine hairs developing on the printĪs such, keep your filament stored in a dry environment with, like in an airtight bag or a box filled with desiccant packs.This absorbed moisture in the filament is not a problem once the part has been printed but does present a problem during printing and can result in a 3D printed part with: + Keep Your Filament DryĪSA is a hygroscopic material meaning it will absorb moisture from the surrounding air. + Print with slow fan speedsĭecrease your fan speed to a speed of 20-30%, you will achieve an optimal balance between cooling and reducing warping and shrinkage. In addition to helping to reduce warping on your printer, these upgrades will facilitate trouble-free part removal, extending the time between calibrations of the bed level.
When printing in ASA we recommend investing in textured print surfaces like our Ziflex or PEI Build Surfaces to assist in keeping your print anchored to the build plate. For this reason, you'll want to ensure your printer is equipped with both to ensure your part stays warp-free and stuck to the bed. When compared with ABS, ASA experiences less shrinkage when cooling (0.7% versus 1.6% for ABS), but the problem is not entirely non-existent. If you haven't gathered by now, having both and heated build surface and an enclosure are a must when printing in ASA. + Have the right equipment before starting.
