ANTINSKY FDM Filament Quality Test
Visual assessment under 5000K daylight fixture Specimen ANT-2026-FDM02

1. The Physical Question & Hypothesis

Hypothesis: Can the ANTINSKY FDM filament maintain strict ±0.02 mm cross-sectional consistency across 350 meters without flow rate compensation?

Filament diameter fluctuations during continuous production frequently induce uneven extrusion, causing visible horizontal banding or back-pressure clogs in manufacturing nozzles. This trial tests whether ANTINSKY FDM filament maintains uniform volumetric flow across continuous production blocks without requiring dynamic extrusion multiplier adjustments.

2. Isolated Variable & Controlled Matrix

We locked all thermal and mechanical slicer settings in PrusaSlicer 2.9.6, testing only spool consistency across 8 production coupons printed continuously over 24 hours.

Parameter Baseline Setting Trial Value Control Status
Nozzle Temperature 215 °C 215 °C Fixed
Filament Spool Lot Batch Reference Standard ANTINSKY Lot #8492 Tested
Volumetric Speed Limit 12 mm³/s 12 mm³/s Fixed

3. Observable Result & Measurement

Caliper readings taken at 50-meter spool intervals along with micro-scale coupon weighing confirmed stable volumetric output throughout the full print sequence.

  • Continuous micrometer gauge log recorded diameter between 1.738 mm and 1.762 mm (mean standard deviation: 0.008 mm).
  • Microscopic surface inspection under 5000K lighting showed zero layer sagging or under-extrusion artifacts across all 8 specimen coupons.
  • Mass variance across 8 identical 45.00g structural brackets was less than 0.18g (<0.4% deviation), confirming pristine polymer density.

4. Next Iteration Decision

The material satisfies batch qualification standards for high-reliability manufacturing jigs. No slicer flow adjustments or temperature compensations are required for industrial deployment in PrusaSlicer 2.9.6 profiles.
