1.4 times stronger than standard PLA at 57 MPa of max tensile strength.


1.3 times tougher than standard PLA with 34 J/m of Impact Toughness.

More Flexible

1.9 times more flexible than PLA with a tensile elongation of 3.4% before failure.

Engineering Grade, Easy To Use

Glass Filled PLA is an effort to advance engineered and practical-use 3D printed parts and components but also is easy to use, just like PLA.

Glass Filled For Durability

When you need extra strength, toughness, and durability in your parts, Glass Filled PLA will do what you need it to. We’ve tested real 3D printed parts in Standard PLA and Glass Filled PLA. We found that Glass Filled PLA is:

  • 1.4 times stronger
  • 1.3 times tougher
  • 1.9 times more flexible

Easy-to-Print, Like PLA

Like standard PLA, Glass Filled PLA allows you to print with ease on any 3D printer capable of printing in PLA.

  • Very low warp
  • Very low odor
  • No special extruder needed
  • No heated bed needed

Filament Quality

3D-Fuel 3D printer filament is manufactured in the USA and Europe using the highest quality materials and technologically advanced manufacturing processes to ensure the best possible 3D printing experience.


Consistent filament diameter means better, more accurate control over filament extrusion amounts.


Perfectly round 3D printer filament prints best. Jams = bad. Perfectly round filament = good!

In-Line Measurement

A multi-axis laser scans the filament 400 times per second as it is being produced, giving unrivaled diameter and ovality tolerance.

Per-Spool Metrics

Know the tolerances. We put the diameter and ovality stats for each spool right on the box.

Test Prints

Each batch of filament is rigorously tested in the field using desktop 3D printers.

Color Consistency

Every spool of a specified color is consistent, whether it’s batch #1 or batch #1,000.
