Guaranteed Color Consistency Every Prusament color is formulated and locked to a documented spectroscopic recipe. We test every batch against the standard before it ships. The result: if you run out mid-project and order a second spool, the colors will match perfectly. Precise Manufacturing & Strict Quality Control Our diameter tolerance is the maximum limit, not an average: when we say the diameter tolerance is ±0.04 mm, the real numbers are much lower. We continuously measure and record diameter and ovality across the full length of every spool and publish the actual data. High Quality You Can Check Yourself Every Prusament spool comes with the actual measured data from manufacturing: diameter readings along the entire length, weight, and ovality. We're the only filament manufacturer in the world that does this. Perfect Winding On Every Spool Our PLA filament is wound under controlled tension on precision machines. Every spool goes through a final inspection before shipping. The result is a spool that feeds smoothly from start to finish. Also, it looks great every time. Why To Choose Prusament Made In The EU And USA Flexible and durable under extreme conditions The Prusament TPU 95A offers very low moisture absorption and high hydrolysis resistance. Its high elasticity and impact resistance remain even at low temperatures (as low as -50 °C). Finally, this material is resistant to microbial degradation, comes with good temperature resistance (HDT 78.6 °C at 1.80 MPa), and great chemical resistance (mostly to oil and grease). Precise and consistent diameter TPU (in general) is hard to manufacture while maintaining a precise and consistent diameter. Most manufacturers don’t consider this issue and simply sell their filaments with significantly varying diameters. We can proudly say that our TPU is truly 1.75 mm in diameter; however, for maximum transparency, we’re stating 0.06 mm as the highest tolerance. As always, you can check each individual spool for manufacturin
