What does high precision mean on this filament?
It means the strand is held at a nominal 1.75mm on a round spool and checked by laser on the running strand, so the cross-section the extruder sees is steadier and the walls of copy forty match the walls of copy one. We quote the nominal diameter and the net weight; where a drawing needs a tolerance band we will say what we can document rather than publish a figure we cannot back.
