Flexible TPU 3D Printers Filament 1.75mm Color is Clear Accuracy +/- 0.05mm Net Weight 1KG(2.2LB) Transparent TPU Hardness 95A…

【1.75MM TPU(flexible) FILAMENT】 The TPU(flexible) filaments are useful in a broad range of printing applications which have the advantage of Low-Odor and Low-Warp. Compared with traditional brittle TPU(flexible), TRONXY 3D printer filaments have adjusted the degradability of the material for optimal performance, so TRONXY TPU(flexible) filaments are not brittle during 3D printing jobs.
【+/-0.02MM TOLERANCE】TRONXY TPU(flexible) 3D printer filaments are produced with more precise specification and have a tolerance of only +/- 0.02 mm. No matter which 3D printer you are using, the consistently round diameters provide optimum flow through the extruder nozzle. Almost all 1.75 mm-specification 3d printers in the market are configured to run with the TPU(flexible) 3D printing filaments.
【VACUUMED SEALED PACKAGING】Some 3D printing materials can be negatively affected by moisture, so this is why TRONXY 3D printer filaments are all vacuumed sealed along with a desiccant pack. This will enable you to easily keep your 3D printer filaments at an optimal storage condition and free from dust or dirt before opening the vacuumed sealed packaging.
【100% ENVIRONMENTAL FRIENDLY】TRONXY 3D printer filaments comply with the Restriction of Hazardous Substance (....
