Estimates based on a ¥13/kg price difference. Actual savings depend on your filament prices and usage.

① Servo-Driven Active Feeding

Conventional spool holders feed passively — the extruder must drag filament off the spool, so heavy spools add resistance and tension changes whenever feed speed changes. This system uses a servo motor to actively feed filament according to printing demand, while tension is set independently by a tension spring — fully decoupled from spool weight and resistance. That's what makes heavy 8 kg spools practical.

② Constant Tension Output

Built-in tension stabilization keeps the set tension constant throughout the entire print. Changes in feed speed, or in resistance from the tension rod and guide rollers, do not affect it — for smooth, stable feeding and fewer under-extrusion or tangling issues.

③ Lower Material Cost — Save ¥13/kg

Use large industrial spools up to 8 kg and buy bulk filament at a lower price. In real user data, filament cost dropped from ¥28/kg to ¥15/kg — about 46% less. The more you print, the more you save.

④ 8× Capacity, 87.5% Fewer Spool Changes

One 8 kg spool replaces eight 1 kg spools. Getting through 8 kg of filament used to take 8 spool changes — now it takes 1. Less leftover filament waste, fewer failed threadings and less re-calibration.

⑤ Save Labor, Run Unattended

Fewer changes, fewer stops and less re-calibration. Long and overnight jobs run without interruption, and the same staff can look after more printers.

⑥ Flexible Spool Sizes, 0.2–8 kg

Test new materials on small 0.2 kg spools and run production on 8 kg spools — one feeder handles both.

⑦ Easy Upgrade

Add-on design for existing FDM printers — no need to replace your equipment.
