PLA Lightweight is a material that changes its structure when heated in the nozzle. The additives inside the polymer rapidly expand during printing, giving the filament a distinctive foamy structure.
Due to the polymer's rapid expansion, the prints are up to 65 % lighter. This makes it perfectly suitable for any project where every gram counts. This includes drones, planes, airships, and other projects meant to fly.
The material's foamy structure significantly decreases filament consumption. It is possible to print 2-3 times as many models from one spool as with regular PLA.
The printed models get a highly attractive matte, rough surface finish. The resulting texture hides the layer lines characteristic of FDM 3D printing, making it a great choice for interior design and other applications where a visible 3D-printing structure isn't desired.
The high number of air pockets inside the polymer works as a thermal insulator. Some specific applications may benefit from this feature: bottle sleeves, thermal box insulation inserts, etc. Like this Soda Can Thermos by LoboCNC
The lightweight properties are also great for making cosplay props and costume parts, as they are much more comfortable to wear.
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.

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.
