Consistency is the whole game in filament. Our extrusion lines, QC lab and batch system exist for one reason: spool #10,000 prints exactly like spool #1.
Virgin polymer certificates and melt-flow index verified before any batch is approved for production.
Automated gravimetric dosing keeps color and additives exact — no guesswork, no drift mid-run.
Temperature, pressure and line speed are logged every second across all 28 lines.
High-frequency laser sensors measure diameter in real time; out-of-tolerance filament is rejected on the spot.
Even, tension-controlled winding prevents tangles and cross-overs — verified by run-out tests.
Each spool is vacuum-packed with desiccant, then moisture-checked before boxing.
Tensile, impact, HDT, roundness and color ΔE measured on every production lot.
Batch code on every spool links back to resin lots, machine logs and lab reports.
Our QC lab runs standardized tests on every lot, and our test prints are measured with calibrated instruments — the numbers on our spec sheets are real.

Hygroscopic materials (PA, PC, PETG, TPU) absorb moisture from the air, causing bubbles, stringing and weak layers. Every VOXFIL spool ships vacuum-sealed and dry.
