Can't post it on r/3dprinting till monday, so I'm putting it here

All printers have their place. For mass production my Bambus are my go to but for prototyping my FLSun S1 pro is by far the better machine

3D printer table

Vibration isn't relevant on modern printers with input shaping. I have my q2 on this table along with my flsun s1 pro, I have no issues. Even with both printers working at the same time.

The FLSUN S1 promises speed but the print quality is poor. What should I do?

give me your honest reviews of FLSUN

I love my S1 Pro, though it took a week of dialing in and figuring out settings to make it print at a similar quality to my Bambu A1 Mini. But once that was figured out, it’s been great! Print quality is fantastic and it’s so fast, even with my setting tuned to favor print quality! One thing I’ve ex

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

I just love this coaster/can holder! 🤩

Hej Smoker aka Viking aka u/Smokerdude420_DK Jeg faldt lige over din profil på r/FLSUNDelta .. Jeg købte en FLSUN S1 Pro for to uger siden, jeg fik en cuponcode til deres EU side så den kom ned til 650€ , det virkede som et godt tilbud.

Which one to get?

At that price, I would go for the s1 pro. I dont think they're worth the 999+ flsun are selling them for, but at 499, I would pick up one or two

Fast printer under 1300 euros ?

For PCCF, I'd recommend the Qidi q2. Its better set up to handle abrasives and more demanding filaments that require a heated chamber. The hotend reaches up to 370C, the bed up to 120C, the actively heated chamber up to 65C. Although, if you are solely after speed, nothing beats the delta printers m

Help: Flsun deletes my Facebook posts!

I commented on a post yesterday lamenting on parts availability for the S1 Pro. Admin is an FLSUN employee it seems, so he had me message him. He located parts for me. There’s more to this if they keep deleting your posts, or I’m just obscenely lucky with my customer support experiences with them so
