FLSUN SR Super Racer Delta 3D printer review: 300mm/s High-speed 3D printing challenge, Pros & Cons

[@anoncodplayer2270]

Whenever I am searching for printer reviews, I am NEVER disappointed to see that you already have a review video. Always detailed and very well thought-out videos.

[@julhcoh]

I am a professional in the 3D printing industry making rocket engines and other industrial parts-- this is one of the best review channels on KZbin. Well done, reach out when you need a job!

[@dontwanttousemyrealnametol6765]

😀milliLITERS per second should become the next unit of measurement for super fast printing. Also "Benchy per KWh" for power usage.

[@returntomonke503]

I use a tub of molten plastic and industrial pumps instead of extruders so I can print at kiloliters per second 🙃

[@TestTest-eb8jr]

I love you and your reviews, your smile in the "bloopers" is contagious 😊😊😊

[@jasonwu2758]

Another great overview. I've racked up 200hrs and the fan ducts really do help even on the stock fans. Awaiting on a OMG V2 extruder coming soon and will upgrade fans when I need maximum speed, cant wait! Thanks again for all your hard work you both!

[@jmiller3921]

What can be said... It's another great 3D Printer review from the talented Aurora Tech team. I learn a lot about the industry by watching these videos. The Pros and Cons section have well thought out critiques that are impressive. This video was extra fun because the printer was just about as tall as the reviewer... but that never stopped her from taking full control of the situation... and making useful improvements to the overall outcome. Thanks for another useful review... I like watching this channel grow very much.

[@mikebroom1866]

This is the printer I've had my eye on after my Ender 3 V2. This and an Ender 3 S1 are the 2 printer setup I really want.

[@tribaladventures]

Im new to 3D printing and this is my first printer- your review and information is and video just TOP Notch keep it up!! Thank you

[@ryangamble5131]

I love my super racer. I definitely agree with the roller and fan duct replacement. I also recommend replacing the internals on the clone bmg with trianglelabs bmg kit as stock didn't last long at all

[@reinerreinbrech7431]

You already become my favorit 3D Printing reviewer. Great work! Only little thing I missed was a comparison by price with other common printers.

[@ryangamble5131]

Not many comparable Delta printers out there for the price (500-600)

[@Crenzill]

I have one of the older Flsun delta printers and was super impressed by it when I first started 3d printing. I had been tempted to buy the super racer, and now I'm tempted again

[@ryangamble5131]

Wait for the new 400 they are about to drop

[@yeroca]

Great review and nicely engineered upgrades. FLSun should be paying you for those!

[@carlos.galhano]

I loved the video congratulations. I have a FLsun SR, but I've only been using it for a short time. I had some problems, one of them was that the film that covers the base tore when removing a piece. And now I'm left with a torn base. Another issue is that I find the extruder very weak, the gear wheels quickly become ground.

[@jordanmccallum1234]

love the fan upgrade. Also, this printer benefits nicely from a 0.6mm nozzle upgrade wrt print times.

[@Reisskraft]

You had me at Speed Racer. Love my FLSUN SR.

[@chrismay2298]

With Klipper and a Sherpa mini, these machines are VERY hard to beat. Especially when Microcenter has them on flash sale for $250 now and then!

[@marshallkarp]

Thank you, Aurora and Brother.

[@aware2action]

Much more than a good review. The upgrades are a nice touch. Need to chew a few M&M's beforehand, to keep things less stressful😂❤👍

[@sherried2114]

Thanks for the review. I am in the process of trying to decide which printer to get and I have watched several of your reviews.

[@3dexperiments]

It would be interesting to see if you could get even more speed and/or quality by installing Klipper and using resonance tuning.

[@aps3000miki]

So, they send you a Delta printer for review, you put it up, print and make this great video in one week? Would take me longer to read the manual and make the bloopers. Besides, this review is Fan-Tas-Tic again, thank you. I love the robotic motion of the Delta printers, fascinating like a camp fire. Again, I learned a lot. Keep it up Aurora and Helios, you are doing a great job. 19k subscribers, unreal. Have fun.

[@NeilWNC]

Aurora Tech -- really great job as always! Based on your review I picked up a Super Racer and immediately replaced the ducts with the recommended improved versions. I added a pei-coated magnetic bed, but had adhesion problems until I slowed down and reduced the height of the first layer. I also roughened up the smooth pei with 400 grit sandpaper, cleaned with alcohol. Adhesion is now very good, and it's much easier to remove large parts. I am having a problem with the filament sensor, the printer just keeps going after the plastic runs out, even though the little blue light is off. Not sure what's up. Finally I found the Cura settings did not produce good quality infill (blobby and rough), it's just moving too fast. I reduced the infill speed by about 40%, kept everything else the same. Infill is now clean and only added a little to overall print times. In short, love this printer so far, it's my fastest yet!

[@NeilWNC]

Update on my filament sensor problem. I solved it by carefully studying the output from Cura (which worked). Apparently the extruder in the SR must be run in absolute, not relative mode. This was an easy change in Simplify3d, and now the sensor works brilliantly. If anyone wants my Simplify3d V5 profile, post here and I'll make it available.

[@emilcost8613]

I have the printer. I love it so much. It's a work horse. So well engineered and reliable. Beautiful prints. It's just a pleasure to use and watch. Great video!

[@J.D.Vision]

I'm waiting patiently for the V400

[@mdcoolcomrat]

Can you please try connecting this printer to Klipper and tuning the input shaper + pressure advance. This printer seems very capable, we want to see what it can achieve with proper software.

[@charlesmedlock5084]

Loved the outtakes!

[@AdrianLabs]

I really like your videos, your MK3S+ assembly guide made me buy the kit and try it instead of the assembled one, thanks for the AWESOME work on this video to everyone involved! Now, I hope you guys give it a shot at building a VORON V0.1, I just ordered a complete kit from FYSETC and have not seen any build videos about it, it's going to be a good challenge, hope you guys give it a try too!

[@JayTdub13]

This video is excellent. I’m very impressed! I’m considering getting an SR. My QQS isn’t my favorite printer…

[@bernatix]

Hey great review! I hope you wrote a invoice to FLSUN. Making good modifications is not reviewing, its consulting and engineering work. They should pay you for it. But why doesnt it go 3x as fast as an ender? It should with your mm/s number.... acceleration is the key. I think you should take that into consideration when talking speed. Going to 200mm/s, upping the outer layer speed closer to the max speed, and upping acceleration could do more than just plainly going to 300mm/s ;)

[@g.s.3389]

I have a first generation CR10, just like many other people, given your experience it would be nice a video where you upgrade to last gen 3d printer such an old and nice 3d printer.

[@JaysCashVault]

Dude I love this channel

[@vguy87]

great review but you should have stated that the flsun was going to release a newer version soon so they dont have buyers remorse

[@OpenFilmmaker]

What 3d printer would you recommend to print camera lens caps and other small parts that need precision?

[@marcroix1]

gracias por compartir, esta increible el revisado, que stl ocupas para el rollo de pla, porque no es el mismo que está en la descripción, gracias nuevamente

[@odycam]

Can you help me with configuring Cura please? To print to the FLSUN SR. I have had this printer for one month and have not been able to print with it. The model gets knocked off the bed every time. Not sticking to the bed apparently. Thank you.

[@sonik3406]

Thanks for the video. Nice and thorough test. I wonder how this printer would do with a larger nozzle and with TPU.

[@chedil08]

Hi, i like your way to test so much, I' d really appreciate if you could share your petg cura profile. Thanks again

[@PaulB-justme]

Watching this video review in March 2024 is fascinating - the review is saying that a 45 minute benchy is really fast! However, recent reviews are saying that a 12 minute benchy is fast! How much 3D printers have advanced in around a year! 😮

[@pen25]

wow. already up to 19k subs. that didnt take long.

[@zenholistichealing]

Great videos as always! Can you please do a video with the Flsun SR with Klipper? Thank you in advance!

[@Dragonrc.]

I got this printer after your review and it really is a great from what I can tell but I cannot fix the stringing. Any thoughts on this?

[@easy_3d]

What settings have you used for the batman and Thanos? What is the layer height, what is the speed? Infill?

[@veracity91]

Hey aurora! i love your channel! you are so inpiring, such young talent! I WAS WONDERING! what camera or App your using to get the timelapse? 😃

[@ajo.5476]

Now that the flsun speeder pad is out. Do you think you can run the SR using the speeder pad to see if speed and print quality are increased? Would love to see that review and the process of doing that

[@JaysCashVault]

Do you have any videos on updating the extruder for this

[@odycam]

Is there a config that can be sent to upload to the SD card and add to the printer? I also have a PI that I will be adding to all of my printers. Thank you in advance.

[@easy_3d]

Many people said its a bit difficult to remove the model from print plate? Did you have to wait like 30mins before removing the model?

[@GTW-1807]

Great video! On the basis of your review I order an SR yesterday and it should be here this week. In the meantime I used your link to go and get the revised fan duct and print it out. However, at the link for thingiverse there are two different fan ducts? An "S" and a "L" duct. Not sure which one to download? I did print the "S" duct but don't know if that's the right one for a stock out of the box Super Racer. Any help would be appreciated... Thanks, Gerry

[@charlesrestivo870]

Sorry to bother you but you didnt mention the voltage on the replacement fans and If they are a direct plug in or do they have to be soldered Thank you for your time

[@alanjohnson1548]

Hi, NEED SOME HELP, I’m just getting into the world of 3d printers, I want to know which machine I can start with it that doesn’t kill my pockets, something that I can updated little by little, I had watch a couple of your video and I really like the LK5 PRO FMD 3d printer and FLSUN SUPER Racer, which one should I choose, does it work spend the extra? I really don’t want to spend more than 400, or there is any other recommendation besides these 2? Just FYI- I would like to create hydroponic systems and large stuff.

[@Jbobonline]

Interesting! Do you think you could relate to Wi-Fi printing and print monitoring in a future video? I used to have an artillery sidewinder x1 with octoprint and it were “must have” features for me. Today I am with flashforge adventurer 4 which has these features embedded and it really is nice.

[@yeroca]

I agree. New printer designs ought to come with Wifi support by default. SD cards feel so retro.

[@corrado352]

I'm looking to buy my first printer. Would you recommend this over a prusa mini?

[@crpton24]

What cura settings did you use for PETG?

[@motoformprototyping]

Great vid, when can we expect a V400 review?

[@AuroraTech]

The V400 review video will be posted on Oct 30.

[@nghialieu2998]

Please review FLSUN V400

[@JeffApel]

Hi! There are many options on the amazon link for the fan upgrade. Do you know specifically which one to purchase? There's the DC12V, DC24V, and 39in variants

[@AuroraTech]

Just DC24V would be fine, you don't need 39" extra-long cable as you are going to cut it and connect it to the original wires.

[@supercrash1991]

Hello is it possible to share the fan ducts I just bought 2 printers like that so I would like to make it for them, please

[@dabruuzer]

Another great vid. Thank you both for what you do; as a noob to 3D printing, your reviews, etc. are invaluable to me. I just ordered a Super Racer at a great price directly from Flsun as my 1st printer, and will do at least the fan duct and filament holder upgrades (thanks for providing the file links!). Do you still like the SR, or has your opinion changed at all?

[@doc8732]

This is amazing! Between this one and the 400 which one you recommend?

[@F_K3NT_D]

Great video. I’m very interested in this machine. $500 is too much for me to try one out though

[@julianthomas2742]

informative video as usual! the free fan duct stl is such an amazing thing to do. If i wanted to replace my extruder and hot end, do you have recommendation? It seems the extruder debate is between a BMG, OMG V2, and Sherpa Mini

[@chrismay2298]

Just did the sherpa mini on my Klippered SR. It's a completely different machine. Was already an absolute workhorse!

[@BlownUpp]

Thanks for the helpful video! I’ve been enjoying this printer a lot so far but I’m also a noob to 3D printing - what sort of retraction settings and print temperatures are you using for PLA? I’ve been having some issues with stringing intermittently while printing at less than half the speed of in this video. I really appreciate the upgrade links - once this print finishes I’ll be upgrading my ducts, blowers and hot end (allllll metal baby!) Thanks again!

[@rolandmine6693]

11:14 man you didn’t have to do my boy thanos like that 😔

[@julianthomas2742]

hey guys, i printed and installed your fans but they dont seem to be an even distance from the nozzle on both sides. Is this intentional or a limitation of the design?

[@TheLuthig]

wonderful review! I just discovered your channel and I love your reviews. I've seen both this one and the Artillery X2 one and since they are both around the same price range, I can't decide between the two. Any recommendations?

[@cristianjosadec]

Now V400 , 400mm a beast!

[@br0k3nilluzion]

Love the content !! wanting to get this printer. Are you going to mod this with Teaching Tech's bed mod?

[@AuroraTech]

I mainly print PLA with this printer, the glass bed won't swing back and forth like a Cartesian printer, and it sticks PLA perfectly fine. I may not do any changes to the bed.

[@tweekFPV]

👍🏻👍🏻

[@AuroraTech]

You are so fast, faster than the FLSUN SR :)

[@haylspa]

when you going to build a Voron?

[@mustafaktas54]

Im feel in love this printer!

[@saethrith]

Are the upgraded fan ducts ok printed in PLA or should I print them in ABS? It's been great watching your channel grow. Keep up the great work!

[@AuroraTech]

It would be better to print with PETG or ABS, but PLA also works as it’s still a few mm away from the heat.

[@saethrith]

@@AuroraTech Thanks! I'm getting a ton of stringing off default Cura settings. Hopefully the fan duct upgrade will help.

[@lugoluciano]

profile sr 300mm/s?

[@jimleesur5610]

What upgraded fans do i need to get if i get this? and where can i get the files for the new fan ducts? thanks for any info!

You need two 5015 blowers, I put all the links under the video description including 3D printed parts.

[@allenhuffman]

KZbinrs continue to call this the Speed Racer. FLSUN should just change the name at this point ;’

[@monzter221]

this or the ender 3 s1/pro?

[@AuroraTech]

If you print PLA most of the time and occasionally PETG and ABS, this printer is the best. If you need to print other filaments like Nylon, Carbon fiber, PC, you need the Ender3 S1 Pro.

[@monzter221]

@@AuroraTech what about the quality of prints between the regular ender s1 pro and the flsun sr? I'm willing to wait as long as the quality is good

[@AuroraTech]

The layer lines of the FLSUN SR are better than Ender-3 S1 Pro, Prusa MK3S+, or any Cartesian style printer that swing the print bed back and forth. But if you print something with a crazy amount of retraction like the Eiffel tower, a machine with a direct extruder prints better than the machine with a Bowden set up. So, it really depends on what you print.

[@monzter221]
