Our Tough Pro PLA+ is the best PLA filament for 3D printing your most demanding projects. When you're looking for a tough PLA with excellent temperature resistance that prints as smooth as butter, Tough Pro PLA+ is the material for you.

Manufactured in the US from genuine NatureWorks™ 3D870 Ingeo PLA, Pro PLA+ offers a third-generation level of material engineering for 3D printing. Since it's a NatureWorks PLA material, it's a sustainably sourced bio-plastic with an incredible eco-profile. 

Filament Quality: 
All 3D-Fuel 3D printer filament is manufactured in United States production facilities.  We have exceptional control over the manufacturing process and can ensure consistent quality for every spool.

Diameter Tolerance: 
Our filament diameter tolerance is +/- 0.02 mm.

High filament diameter variability can cause big problems in your 3D printer. We use a multi-axis laser measurement system to control our filament diameter and ovality in real-time during production. Every spool has the diameter and ovality measurements listed right on the box.

Packing Information: 
A full 1kg (2.2lbs) of Tough Pro PLA+ plastic filament arrives on an easy-to-use plastic reel and is vacuum sealed with a desiccant packet to keep out any moisture.

Test Printing: 
The 3D-Fuel test lab features multiple brands of 3D printers including Bambu Lab, Raise3D, MakerBot, LulzBot, Prusa, Creality, and more. We 3D print what we manufacture to ensure that our filament provides the absolute best quality possible.
