Review on PolyFlex 1 75 Mm 750G Black by Steve Campbell

Revainrating 4 out of 5

VERY Flexible TPU Filament

This filament is much softer and more flexible than other brands 95A TPU filament which makes me wonder what shore hardness really is as it seems to be significantly softer than 95A . Because it's so soft that the extruder gears need a very high flow rate to properly grab and push through, even at 140% flow I couldn't completely eliminate underextrusion with it. In general, this filament is too soft.
