Review on Get Precise Results With HATCHBOX TPU 3D Printer Filament - 1Kg Spool, Shore 95A, Silver by Dave White

This was the very first flexible filament I tried. It prints well once dialed in and it was relatively easy to get dialed in. I'm running it on a modified FT-5 (titan aero + volcano) at 0.4mm with an 0.8mm nozzle and it's performing perfectly. Sticks well to cold glass with aquanet. Makes for very strong, flexible models. Layer adhesion is excellent as with most TPU filament. Even one or two layers thick makes a near impossible-to-tear bond. Hatchbox is a great filament brand in general. Been using all their products for years
