Almost Unbreakable!: PolyMax PLA is an engineered filament with enhanced toughness, ductility, and durability. This PLA filament is ideal for applications requiring high impact resistance, with mechanical properties comparable to ABS. PolyMax PLA combines excellent strength with great printability. Tangle-Free & Moisture-Free - PolyMax PLA filament is carefully wound to prevent tangling, dried, and vacuum sealed in a resealable ziplock bag with desiccant. Always hold the filament tip to avoid nodes, and use the holes on the spool to help prevent this issue.
