Prusament is a premium-grade material made by the same people who build the printers. Every spool is manufactured in-house with consistent color and high diameter precision. You can verify it yourself, down to the last meter.
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.
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.
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.
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.
Prusament is manufactured in our facilities in the Czech Republic (Europe) and Delaware (United States). That means faster shipping, lower import duties where applicable, and a supply chain under our full control.
There's no third-party manufacturer who can quietly change a raw material supplier. No surprise batch failures from a factory you've never visited.
ASA's one of the main advantages is excellent UV resistance. This, in combination with good high-temperature resistance, makes it perfectly suitable for making outdoor parts with a long lifespan. Here's a great example: Czech company Anitra System uses Prusament ASA for making GPS loggers attached to migratory birds, where long lifespan and high resistance are necessary.
ASA is soluble in acetone. When exposed to acetone vapors, the model's surface melts and forms a glossy finish, hiding print layers and imperfections. The result resembles an injection-molded part. You can learn more about chemical smoothing in our blog article.
Unlike other technical materials, ASA offers little to no stringing. This makes it suitable for printing tiny, detailed parts, such as tabletop figures and similar models.

Starting October 2025, all Prusament filaments ship on a redesigned spool with a fully rewritable NFC tag powered by the OpenPrintTag standard.
The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app. It works entirely offline, it is free to extend, and open for anyone to build upon.
