Filament Price Tracker monitors 14,934 active listings across 425 brands, updated every 4 hours and normalized to a true cost per kilogram so you can compare materials and spool sizes on a level playing field.
Every product has its own page with the current price, true cost per kilogram, and how it stacks up against the market average, plus a direct link to the best current deal, no account needed. We also track the gear that keeps filament printable, dryers, dry boxes, and storage, in the Dryers & Storage section.
Plus in-depth guides, news, and analysis on filament types, print settings, and the broader 3D printing market.
TPU (thermoplastic polyurethane) is a flexible, rubber-like filament used for phone cases, gaskets, seals, and vibration dampers. It prints at moderate temperatures but needs a slow, steady feed, and a direct-drive extruder handles it far better than a Bowden setup. Softer grades (lower shore hardness) are more elastic and harder to print.
Best for flexible, rubber-like parts such as phone cases, gaskets, and vibration dampers.
