Filament Quality

3D-Fuel 3D printer filament is manufactured to demanding performance specifications because your 3D printer deserves the best. We believe that your 3D printer filament should be a help, not a hindrance to your 3D printing experience.  That’s why we developed a rigorous quality testing system, to ensure that you have the highest quality 3D printer filament, period.

Diameter

The ability to control the flow of your filament makes printing easier and more consistent. One of the major factors affecting this control is filament diameter. If your 3D printer believes it is receiving one diameter of filament, it will set the extrusion speed accordingly, extruding a perfect amount. The printer has no way to adjust on the fly, so if the filament diameter fluctuates then the amount it extrudes will be inconsistent. This can lead to blobby prints due to over-extrusion or weak prints due to under-extrusion.

Ovality

Perfectly round 3D printer filament prints best. If it has too much ovality, it may cause the filament to twist, extrude unevenly, or jam in your printer.  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. Many other 3D printer filament manufacturers only measure after the filament has been produced using a small sampling of the total production. Our filament is guaranteed to be within +/- 0.05mm of the stated diameter.

Per-Spool Metrics

Know the tolerances of each spool of filament, posted right on the box! We are the only 3D printer filament manufacturers that will reveal, on a per-spool basis, the spool’s tolerance and performance characteristics.

Test Prints

Each batch of filament is rigorously tested in the field using desktop 3D printers to ensure that melting temperatures and surface finish are consistent and of the highest quality.
