Automatic Filament Reloads
![Automatic filament reload on Infinity Flow S1 captured in a GIF for seamless print farm operation](http://infinityflow3d.com/cdn/shop/files/Automatic_Reload_3.gif?v=1727706885&width=1500)
The S1 takes the hassle out of 3D printing by automating filament changes and eliminating downtime.
No more babysitting your printer or worrying about wasted filament—just seamless, uninterrupted printing so you can focus on what matters most: your projects.
![Infinity Flow S1 transitioning between filaments during automatic reload for print farms](http://infinityflow3d.com/cdn/shop/files/Automatic_Reload_8664ac85-b7e9-4d4c-a48a-96e0c4e2d19e.png?v=1727706982&width=1500)
The S1 is designed for back-to-back filament transitions, automatically loading the next spool as soon as the first one runs out.
- Seamlessly switches between two spools without stopping your print.
- Automatically loads the next spool when the first one runs out.
- Keeps your printer running continuously, no manual intervention needed.
No More Wasted Filament

The S1 uses every inch of filament on the spool to eliminate filament waste.
- Maximizes filament usage by switching spools seamlessly.
- No more wasted filament at the end of every spool.
- Save money by reducing waste.
Reload Filament While Printing

The S1 allows live filament loading, meaning you can reload filament while printing to maximize your printer’s productivity!
Will This Work With My Printer?
![Compatibility requirements for the Infinity Flow S1](http://infinityflow3d.com/cdn/shop/files/Printer_Requirements_short.png?v=1730386992&width=1500)
The Infinity Flow S1 is designed to be compatible with most FDM 3D printers that use 1.75mm filament. It requires no firmware modifications, so setup is simple and straightforward.
![nfinity Flow S1 installed on various 3D printers, replacing systems like Bambu AMS and Prusa MMU with automatic filament reloads](http://infinityflow3d.com/cdn/shop/files/Adapter_Gif.gif?v=1727708718&width=1500)
All you need is an adapter to connect a Bowden tube to the inlet of your printer’s extruder if your printer doesn’t already have one.
Just what we needed- after some modifications to our Lab we are going to buy many many more.
Awesome to hear!! We do offer bulk discounts so if you plan to order a large amount feel free to request a price quote. There is a link on our contact page.
I think you’re created a really great product! So far no problems. Great to using up leftover filament.
The Infinity Flow S1 works as described. I typically print in 1 color and have AMS systems mostly for automatic spool swapping. The AMS systems have a lot of jamming issues and errors which is time consuming and irritating. The Infinity Flow’s simple design has eliminated filament errors for me.
