FLSUN S1 - A Tall Tale

Flsun is gonna botsmash ur account now😅

all the printers have been basically same for 10 years now. even bamboos multi material splicer, it's just a mosaic ain't it.

Man i have an flsun SR, and have had nothing but issues with this thing. I CANNOT get good quality prints out of it at all! Not for a lack of trying either. Put loads of time into tuning every single thing you could imagine, but its all for naught. Im never gonna touch another flsun product. In all likelihood my next printer will be a prusa because at this point I cba dealing with this chinese junk. Maybe a bambu but im not a big fan of their closed-source nature. This type of stuff is why in large part ive moved to resin printing. Resin printing is finally at a point where theres little in the way of needed innovation, and for the most part, you can just buy a machine and get printing.

Fair play!

Great and honest review, I really appreciate it. My feeling is also that there is just too much marketing and less of the reality, something like with a hotend stating max flow 70+ but in the underline/testing details you can read it was measured with 1,2mm nozzle printing PLA at 260°C, so an absolutely off the reality measurement, but that is what helps the sales a lot and people accept it. I get that you buy cheap ender 3 and take it as a "finish yourself" printer, but doing the same with 300 or 400+$ printers is weird habit.

Damn, you've sold me on this printer, where is your affiliate link below

mr sausage jumpscare aah

Honestly im happy i went for FlashForge A5M on its hype - it was below 300$ free shipping and it really does what it was advertised (beside 1 issue i am happy with it). Im also sad that i did not go for Sovol08 on first day (it was cheap but got no space for bigger printer despite i need one). Both of those delivered what they promised, maybe not revolutionary tech, but tech that was revolutionary not long ago in acceptable price range.

视频非常好。FLSUN S1本应在2023年发布，却被推迟了半年。我觉得我被骗了。所有的承诺都没有兑现。没有推广的速度，没有可以使用的AI功能，只有开源代码被修改和闭源。打印质量很糟糕。

I havve a prusa mk 3 and it works great and now the xl5 head and i like them and i bought a creality k1 and its a disappointment its printing just shit. I just keep my prusa xl and this will be for a long because it does what i want. I what i learned from Chinese goods they look great and there it stops. Its like the Russian the boran was outside like thespace shuttle but inside its was 1940 stuff same with the concordski. Pay a little more and buy europees of made in the usa. I agree completely with Robert here.

thank you! It's becoming normal expecting that a printer doesn't actually work and people seem fine with it. I bought this printer and I'm guilty, I wasn't expecting the AI stuff to work for example... But honestly I didn't expect it to that bad. Anyway I'm replacing all the electronics now, hopefully I'll have it work (possibly at half the speed)

I still like building my own printers, at least that way when they're unfinished turds it's my fault for not finishing it.

Dont buy this printer! Get their shit sorted! Exactly. That's a good review, honest and true! I appreciate your integrity. And you are right. This does need to stop. I got into printing with the Bambu P1S and just bought a X1C with AMS. Getting a printer that works and not having to spend ANY time troubleshooting and calibrating. Amazing. The lies and the whole releasing a product that doesn't even print correctly with features (like that AI BS) that doesn't work right out of the box, it needs to stop. These guys dont get that there are other printers that do so much better right out of the box. And price comparable. Get your shit together flsun. Nobody wants this crap!

Thanks for this honest video. You are so right with this.

considering the massive fail that was the v400 firmware it's not really surprising that this is also bad

The craziest part is how easily most of these issues could be polished out or avoided entirely with minimal work. They could have an intern with solid printing knowledge bust out print profiles. They could have used an existing slicer instead of their own hack job. They could polish the UI with a few hours of programming. They could simply not lie about capabilities. Like, why? Anyways, thanks for the PSA. It really is annoying we have to sort through so much marketing nonsense and all the buddy buddy reviews.

I mean..... You are so highly spoilt by Bambu printers man. It's a delta printer which has amazing hardware. All you need is to install klipper on your own? That's it? And do the tuning on your own?

Maybe I'm biased because I have built a voron, but it isn't that hard to ask the 3dp community on why your prints are looking like that. The PLA prints look like YOU forgot to switch on cooling lol.

I bought the V400 last year and I pretty much expected that the specs they were claiming it could do would be... misleading at best. But, I figured if it could do half of what it claimed, it was still pretty good. I'm generally happy with it, doing about half of the speed it says it can do. I have non-print seeks going at 400mm/s and it doesn't skip a beat. I replaced the bed with a fiberglass plate that I clamp down, because for large prints with shrink issues, the original bed pulls up and ruins the print. It works quite well now.

Spot on Robert. I refuse to buy another project printer and it sounds like this one is yet one more of those printers. Thanks for fighting the fight!

Didn't they attack another creator's video with bots after he gave them a critical review?

Loved it. I am tinkerer/maker but also a photojournalist and I have found myself getting increasingly frustrated over the years with the shilling most channels do. Even some of the supposedly better ones.
I know the drivers behind it, creators need to be on the good side of the manufacturers to be sent early products to review so they can get their clicks and pay their rent - all the while claming they are independent and no money exchanged hands. But it's a dangerously circle and the manufacturers have been gaining power over reviewers because of this - because if you get on the blacklist, you can't review early and hence no clicks, no income for rent. It happened in all consumer goods areas.

Dodgy sponsors are the other bane, like become a Scottish lord and all that BS. But that's another topic.

I think there's a new (old...) way to be creator and a few are going this way but there's room for more. F*ck the freebies, use the Patreon money to buy what you want to review. Be very, very careful and do your due diligence if you take on sponsors. Soon, a lot of reviews will be AI created/scripted so being the super honest, not-on-the-take, independent human reviewer might actually work. Especially if you already have the followers, perhaps that switch is doable. Unless the YT overlords decide to have the algorithm bury you because people are gullible and there are more clicks in feeding them AI content...

We appreciate the information! Having integrity to say it just like you have is something to take notice of. You and Clough42 are keeping quality first!

Agreed! I've been so underwhelmed by the prints coming off this thing, especially out of the box. They've improved a little bit with firmware/profiles but still I'd rather use their older V400 which doesn't make my ears bleed, and produces close to perfect prints every time. Manufacturers need to put in more effort ensuring these products are ready for launch and meet all the claims they say they're capable off.

I hope I made it clear at the beginning of my S1 video that I am not a reliable source for deep technical FDM knowledge, and there are features this thing has that I didn't even know at the time because I just wanted to get it turned on and printing stuff for my tabletop gaming hobby. I put the focus on the out of box experience from the perspective of someone who sucks at FDM printing, and I hope that wasn't in any way misleading despite my own somewhat negative conclusions.

Thanks for the honest video - I love it. I don't like FLSUN. When they promoted the S1 I was pretty excited but like you, many others pointed out the false claims, yeck! Originally I loved the specs but glad I waited to see how it would perform. Researched a lot and found that their previous machines had lots of software problems as well.

Speaking of Creality, remember the "all metal extruder" for the K1C that ended up being mostly plastic? They lied about that, changed their webpage but their Amazon page still advertises the all metal extruder with 1,000 hours of clog free use. So... now reviewers that Creality sent machines to found out it was plastic, so will it still last for 1,000 hours? Seems pretty sketchy, so Creality is off my list of possible printers as well.

With that said I heard Bambu is coming out with a larger build area printer and with their past performance I have more hope. So going to wait and see what they bring to market. Again thanks for the honest video.

There’s a lot of issues with this machine and misleading marketing such as the status light which is supposed to change color when a print fails or something. Which was not conveyed well as the majority of people ended up thinking it’s how long a print has left to finish

Respect for this. Far too many "reviewers" always gloss over the multitude of flaws most printers release with and tell us to buy them anyway.
I started my 3d printing with an ender 3 pro, got frustrated with it after 5 years of printing, modding, tinkering, fighting with it, and finally gave up on it and jumped on the bambu bandwagon, and it's been an incredibly smooth ride ever since. I started with an A1 mini, now I have two A1s, and A1 mini and I also gave my wife an A1 mini. She's never 3d printed anything, but jumped right in; I showed her the basics of changing filament, adjusting settings and she's been in love with it.

I'm actually excited about the creality K2, but I really don't trust them to release a printer without issues, so I'm waiting for actual reviews. Even then, my bambus have been so reliable, I probably wouldn't buy anything else anyway. I still want another A1.

I'm a hobbyist who sells and builds models, and I can't afford to spend a lot of time and money buying and tinkering with printers. I once bought a Kobra2 (my main at the time was just a Prusa mini) based on reviewer recommendations and I was hugely disappointed with it's print quality and overall features. One reviewer even went as far as to compare it's print quality to SLA. I was naive at the time. I waited and finally got a Bambu and was able to tackle larger projects w decent quality and speed.

But during that period of waiting, time and money was wasted on hardware that I felt lied to about. So it's very important for reviewers to be appropriately critical...I really wince when I see them make recommendations on just a benchy or a limited amount of time actually using the printer. Only to find out months later, on a whim, they mention some major flaw they didn't like about the printer they posted the affiliate link for.

Thank you Robert - I really appreciate the effort and time you put into all your episodes. 👍👍😎👍👍
Maybe one day consumer product manufacturers will do the same.

I know exactly what you mean. I was ready to replace my Bambu Hotend with a different product. I almost entered my purchase info, but I had that nagging feeling I should check some reviews. On the Bambu forms, I read about this product and all the promises made only to discover its marketing hype. And it wasn't cheap. The new design is an open source design, patented in the USA , making a $20.00 hotend retail for $124.98. The reason I was considering replacing my printer's hotend was due to the degraded print quality on my Carbon X1. If you have an X1, and have upgraded your hotend I would appreciate your feedback as I've tried playing with the printer extrusion settings, temperatures and print speeds. I mostly print in PETG, and my hotend nozzle keeps getting filament buildup. The final print layer used to be clean, now it's streaky and the midlayers are leaving random spaghetti strings requiring more post print cleanup. Even new, out of the package sealed filament. I'm sure it's me. But I have also printed 20ish 2KG spools so far on the original .4 mm Nozzle. Thanks in Advance.... James

Love all of this. Well done sir. I had a great laugh 😂

Have the V400 and the Super Racer, both rock!!! When SSH comes out for the S1 it will out perform all others :-)

Good on ya mate, I see critical thinking I subscribe.

$2200.00? lol

Great video. I hope it will help consumers think that a 3D printer is a production machine and not the latest iPhone. The requirements for a production machine are, first of all, reliability in operation, ease of maintenance, and stable quality. This can only be verified by time and not by the statements of advertising managers.

Good honest video. This is why Bambu lab can’t be beat cause they actually put the effort into their features. The rest still just market and under deliver.

its 2024 and the only thing thats new tech in 3dprinting is (klipper) the printers have the same tech they had 5 years ego

I did pre order the s1 since I got the v400 as my first Printer on it's release but I canceled the s1 order exactly because of the crappy software it was like a 100% chance for them to fk up the software again. I got the Qidi X Max 3 instead and I'm super happy with it

Damn, that's a shame... I am so happy to have honest folks like you around to keep us informed. Thank you. It really sucks when you're excited about getting something and then it doesn't meet the expectations... even close. Luckily, my X1 Carbon is doing a good job and hasn't disappointed me, so far.

I hope you're the first sign of the dam breaking on all these brain-dead marketing practices

I don't mind the manufacturers using content creators as part of their sales strategies or other types of aggressive marketing. It's something that can be a win-win for all three parties (manufacturers, content creators, and consumers), but the crap they're doing lately has pushed too far

Take the Creality CFS for example. When they started selling it early June, I was already annoyed because I thought it was a pre-order for stock that wouldn't start shipping for one to two months. Lo and behold, it turned out a limited number of them would ship late October and the bulk of pre-orders (not regular orders, still *pre-orders*) would ship out in early November

And yeah, we're enabling this behavior, because when people pointed out how ludicrous the above was, you had fanboys scolding everyone for not believing in daddy Creality, who were definitely doing something normal and acceptable

I guess to be fair Prusa set that example first, but there's no pandemic to blame this time

Thank you for being an early adopter. So many of us got burned by Kickstarters years ago, we don't go anywhere near them until the product actually ships, and the first revision bugs get worked out ;-)

I remember when I was a kid. Was told "The bold print givith, The fine print takeith away.

I think most reviewers are afraid to give a totally honest review because the machine makers will bypass them on the free machines. Without free machines those reviewers would go the way of the dodo bird. I have a Flashforge creator Pro from 2016 and the same year Simplify 3D slicer. Works fine for what I do. I'm not in the prints for sale business so having the latest and greatest serves no real purpose. Thanks for the comments. Refreshing.

It's pretty sad that Bambu Lab set the standard for printer releases at 'actually does pretty much what we say it can do'. Even a company like Prusa was sleasy advertising input shaper at launch and then taking months to release it for MK4 and many more for the XL. But at least their printers actually work. FLSun is just pathetic with this.

These companies looking to make a sale, and not provide support is exactly why I ordered my bambu printers.

Deltas are pretty to look at but not for most people in terms of operation. They can hardly make a perfect circle

Glorious Flsun is best company, and put other company to shame 😅
