Automate Your Filament Reloads

The S1 takes the hassle out of 3D printing by automating filament changes and eliminating downtime.

Back-to-Back Filament Transitions

Seamlessly switches between two spools without stopping your print.

Live Filament Loading

Allows new filament to be loaded into the system while the printer is actively working, reducing downtime.

For All Spool Sizes

The S1 Plus is available in multiple roller sizes to handle any filament spool size.

Larger rollers can also be used with smaller spools, so you don’t need a different unit for every roll size.
