- Extruder tip bubbles with a burst of steam, stringy or drooly
Precise control over the material’s mass flow rate is directly correlated with the moisture control of printed material. Moisture will lead to hydrolysis, breaking the polymer chains. In addition, while filament is melted in the hotend, moisture turns into vapor inside the hotend’s melting chamber, generating pressure. This pressure needs to be released, release that depends on the material’s viscosity. The result may be a back pressure jam or flow variations in the extrusion.
Heat-based solutions cannot deal with moisture effectively
-
Time - Drying cycles are typically 8-48 hours long
-
Quantity - These solutions cannot process more than a few pounds of material
-
Moisture rate - Achieving a relative humidity of less than 10-30% (depending on the material) is hard or even impossible with such techniques
-
Versatility - Materials with different thermal properties may not be dried simultaneously
-
Performance - Since this method depends on contact with dry air, moisture may be found even after a full drying cycle
-
Cost - Up-to 10 times more energy efficient than heat-based solutions
