S1 OR S1 PRO

AI to the rescue The FLSUN S1 and S1 Pro are both high-speed delta 3D printers, and they share many core features. However, the S1 Pro is an updated version that brings several key improvements and refinements. Think of it less as a complete overhaul and more as an "S1.5" with enhancements that impr

Would a V0 be good for me to bring in my class when I need it?

Vorons are awesome but unless you can find a pre built one idk if that fits the bill. Look into a qidi tech printer. Enclosed decently fast etc or as much as I hate to say it bambulabs makes a smaller printer I hear good stuff about but in class with students enclosed and a filter is a good idea.. j

S1 Pro and Customer Support

I have an S1 Pro. It’s FAST. It sounds like an alien fight when running. It produces pretty decent parts. If you wanted to print slow materials, I wouldn’t bother. But if you’re slapping in high speed filaments… it’s hard to beat. I did flash mine with the FLSUN Open Source firmware which has been a

Does the S1 Pro have the Silencer kit already?

I went through the same confusion when I picked up my Chang li s1 pro a few months ago. From what I can tell, the Pro already has most of the quieter components baked in compared to the standard S1. The stepper drivers and motion tuning seem noticeably better out of the box. That said, the silencer

Swapped my T1 for a T1 Pro today

I've got 2 T1 Pro's, 2 T1-U's that have been upgraded with the FLSun 'quiet kit' and 2 S1 Pro's as part of my farm and as far as I can tell the difference between the T1 Pro and the (upgraded) standard T1-U when it comes to printing is...nothing. No, wait, that's not entirely true. The wake-up 'spla

Just bought an S1

I have a S1 Pro and it has been pretty solid. I would highly recommend getting "high speed" filaments. I have had good luck with Sunlu's HS PLA and Elegoo's Rapid PETG with just default profiles (using OrcaSlicer). I haven't used other filament types outside of that. Be prepared for how loud it is.

FLSUN S1 - FREE

If I lived anywhere near Charlston, S.C. I'd be taking you up on your kind offer. I only have 2 (two) S1 Pro's in my farm but, they both work flawlessly. In fact, most of my FLsun printers are my go-to for fast turnaround. Of course I've also spent time with the machines ( and not just lazy plug & p
