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

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.

Compatibility requirements for the Infinity Flow S1

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.

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.

The S1 works amazing! I don't have to worry about having half spools laying around. I love the fact that you don't have to change any firmware. My only critique would a longer power cord.

Snapmaker Artisan 3 in1

Amazing product in term of quality and price, it will helped me in my personal projects to assure good printing. I liked the idea of having such a product to maintain printing, doesn’t require too much space or even time to assemble. The project team are very amazing and they did provide me with an update along the production process. Highly recommend this product for personal or professional use.

Creality Ender3 V3 Plus and Infimech TX

I have not used this product yet, as I just received in the mail and I was surprised complete assembly is required. So it sits in the box it came in and maybe someday I will get around to putting this together and using it. It looks like it should be a nice unit, however I would have not purchased it had I know I would have to assemble it. I don't buy from Ikea for this exact same reason.

Creality 3D Ender3 v2

Ender 5+

Haven’t had a chance to try it out on the actual printer, yet, but assembly was very quick and straightforward. One suggestion I have would be to increase the infill a bit more, as I had one corner of the spool guide crack as I was installing the rollers (I over tightened just a bit). It was an easy fix, but could be a bit more sturdy. The base layer could also be a little thicker, as there is a lot of flex and bending. Also a longer Allen wrench. The instructions show it extending all the way from one side to the other to attach the guide units to the centre bit, and they aren’t long enough.
