Why To Choose Prusament

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.

  • 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.

  • Spool-level production data can be accessed through the QR code on the spool.

    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.

Made In The EU And USA

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.

Prusament PETG Ultraglow Green

The brightest glow-in-the-dark filament on the market

We used the maximum amount of glowing powder we could achieve while maintaining reliable printability and delivering exceptionally bright luminescence. We felt like there was no strong reason to make another mediocre glow-in-the-dark PLA filament, as the market already has plenty. Instead, we did what we do best: we took it up to eleven.

Mushrooms

Glows all night long

Prusament PETG Ultraglow can be charged by exposing it to both UV (most effective) and visible light sources. When charged, the filament glows strongly for several minutes, then the glow intensity gradually decreases. In total darkness, a weak glow can be visible even after 6-8 hours after charging.

Glow comparison

Brightest of them all

We ordered other branded glowing filaments and put them all to the test. We've kept the other brands anonymous, as the results speak for themselves. Prusament PETG Ultraglow shines by far the brightest when compared to common glow-in-the-dark PLA.

Glowing spool

High safety

Prusament Ultraglow is filled with strontium aluminate, which is a safe alternative to historically used Phosphorus. It's not toxic and neither radioactive.

Basic Attributes

  • Strengths

    • Brightest glow-in-the-dark filament on the market
    • Good high-temperature resistance
    • Low shrinking and warping
    • High strength and durability

  • Worth knowing

    • Highly abrasive material: Needs a hardened nozzle, and accelerated wear on printer components should be expected
    • 0.6 mm nozzle diameter recommended

New spools with OpenPrintTag

Smarter spools. Open standard. No cloud lock-in.

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.

Glowing components

Bonded in Prusament PETG for better mechanical and temperature resistance

We deliberately chose PETG as the base polymer for a reason: it's stronger than commonly used PLA and resists higher temperatures, making it suitable for functional parts. And you can take it further with the XL and other multimaterial solutions. Print functional models in standard PETG and add glowing accents to highlight specific components - switches, handles, indicators, or any part that needs visibility in low light.

Frequently asked questionsAnswers to common questions about this product.
Use a hardened nozzle!

This is the most abrasive material we’ve ever made. This thing eats our manufacturing line's metal components like they were nothing. It will destroy your brass nozzle in no time. We recommend using a 0.6 mm hardened non-high-flow nozzle for the best results. And if you want to be 100% sure, you can use the E3D DiamondBack nozzle , which is harder than strontium aluminate and won't wear out.

A 0.6 mm nozzle diameter is recommended.

While we provide 0.4 mm profiles, we strongly recommend larger diameters to prevent clogging. Standard (non-high-flow) nozzles work better for this material.

Expect accelerated wear on PTFE tubes and hardened components.

This includes hardened steel nozzles and Nextruder gears. Occasional printing won't be an issue, but regular high-volume use will shorten the lifespan of metallic components.

Dry the filament before use (optional).

While PETG doesn't absorb moisture as readily as some filaments, drying after prolonged storage significantly reduces stringing, oozing, and clogging - especially important for multi-color printing (XL). To dry the filament, please follow the instructions in our article .
