Dry Spools and Recycled Filament: Full Lifecycle

Both articles treat filament as a long game, one about keeping it dry so it stays printable, the other about where it came from and whether recycled rPLA and rPETG are worth buying.

In this episode you'll learn:

• Most FFF filaments are hygroscopic and pull water vapor from the air, so a spool absorbs moisture on the shelf, during long prints, or in packaging that does not seal well.

• At melt temperature water molecules irreversibly shorten the polymer chains, producing brittle or oddly flexible prints with reduced thermal and chemical resistance.

• Wet filament shows up as popping and hissing in the nozzle, stringing, oozing, blobs, poor layer adhesion, and under-extrusion that can clog the nozzle.

• Prusament PLA Recycled is made from 100% Prusament PLA production waste, and because colors are mixed without added pigment every batch has a different shade.

• Filamentive uses homogeneous offcuts from partner extruders (fishing line, fencing) and reaches up to 90% recycled content.
