Brand: Yiqiu3D · Soft filament is sold as flexible and then fails as fragile: the part takes a shape once and cracks at the fold the second time it is stretched. This Flexible TPU Filament 330m range is specified for parts that flex again and again - high elasticity, good abrasion and oil resistance, and shock absorption - so straps, sleeves and bumpers keep working instead of tearing at the layer line.
TPU is an elastic polymer, not a rigid one: it stores and returns strain instead of building the stress that splits a rigid layer line. In practice a printed strap, sleeve or bumper can be stretched and released many times without the whitening and cracking you see on a rigid filament at the same fold.
Full answers belowBest for: Where a part must bend and recover: wearables, grips and protective bumpers - 1kg spools; lead colour Colored. Not ideal for: Avoid on direct-drive-less setups at high speed - flexible filament needs a suitable extruder - 1kg spools; lead colour Colored.
Nozzle 220°C
Ordering by colour is where flexible-filament buying usually slows down: buyers see 'coloured' and cannot agree a shade with the factory. We ship coloured TPU with the shade list confirmed with the supplier per order, so the colour is fixed in writing before the order is released, and the spool is wound tight and even so the strand feeds without snagging midway through a print.
1.75mm diameter on a standard round spool, 1 kg net filament per spool and a the nozzle temperature confirmed for this grade, with approximately 330 m of strand on the spool - a generous run for a flexible grade, so one spool covers more wearables than a short roll.
TPU is soft filament: run it on a direct-drive or short Bowden extruder at slow print speeds or the strand buckles between the drive gear and the nozzle. Dropped into that window it feeds like a normal FDM material on Bambu Lab, Creality and Prusa style machines, and the round spool seats in a standard holder or dry box without an adapter.
