Prevents Print Failures

Filament with bent ends, tape, glue, or tangles can jam the S1 and stop your print. The cutter stops that before it happens by cutting off the bad part automatically.

No more:

❌ Clogs

❌ Skipped reloads

❌ Ground or chewed filament

Works With Most 3D Printing Setups

The Infinity Flow Filament Cutter is compatible with a wide range of 3D printing systems that use 1.75 mm filament, including:

  • Automatic Filament Re-loaders (like the S1)
  • Direct-to-extruder Setups
  • Any setup using PTFE tube to guide filament
  • Many AMS/MMU style units

Even without a reloader/AMS, printers with a runout sensor will pause, giving you a chance fix the problem and resume the print.

No Sensors. No Wiring. Just Physics.

🔄 Filament enters the cutter’s tube as it loads into the S1.

⚠️ Bent, taped, glued, or tangled ends gets caught in the inlet tube.

✂️ The tension pulls it down into a hidden blade, which cuts off the bad end before it can jam the S1.

✅ The S1 reloads the next spool and keeps your print running without interruptions.

Installs In 30 seconds (No Tools!)
