Mintion launches W1 electric filament respooler

Chinese company Mintion has launched the W1 Electric Filament Respooler, a tool built to speed up filament transfer and spool organization for makers running multi-color prints and AMS-style workflows. Transferring filament between spools, prepping bulk filament, and saving partially used rolls are tasks many makers handle regularly, and the W1 targets all three.

The W1 covers several filament management tasks: moving third-party filament onto Bambu Lab AMS-compatible spools, converting 3kg bulk filament into standard 1kg spools, and recovering tangled or partially used rolls. Mintion has shown with the recent release of the filtration unit (read our review here) that it can deliver good-quality products at a fair price.

A linear rail guidance system keeps the winding consistent, and three speed modes, silent, normal, and turbo, let users choose between quiet operation and faster transfers. The W1 rewinds a full 1kg spool in under four minutes on turbo mode, though actual times vary with filament type and spool condition.

The W1 is built for simple, single-step operation across those use cases, aimed at makers who switch filaments frequently, run AMS systems, or want a more convenient way to organize their filament collection.

When Mintion opened pre-orders for the W1, the first production batch was set to use 3D printed components. After feedback from users, 3D printing communities, content creators, and distributors, the company moved every pre-order to the injection-molded version instead, for better consistency, durability, and finish. Shipments are scheduled for mid to late September; customers who don’t want to wait can request a refund directly from Mintion.

The W1 is available for pre-order now at an early bird price of $89.99, 25% off the $119.99 regular price, with the injection-molded version shipping as the first batch. More details and specifications are available on Mintion’s product page.
