Simple FLSUN QQ-S Review – Worth Buying or Not?

FLSUN QQ-S Review - 3DPrinterly

3D printing is definitely growing in popularity and as a result we’re seeing plenty of manufacturers getting into the development of 3D printers. FLSUN is up there with their release of the FLSUN QQ-S (Amazon).

The QQ-S 3D printer offers a bigger printing size of φ225 x 360 mm which is perfect for most projects or designs out there.

It has a whole host of features that give it the ability to print fast, reliable and even remotely using Wi-Fi. The all-metal structure gives it that solid foundation necessary for high quality prints, along with the precision in its physical dimensions.

The futuristic, clean look of this 3D printer is desired by many so this review will look in-depth at the FLSUN QQ-S to determine whether it’s worth buying or not.

Features of the FLSUN QQ-S

  • All Metal Structure
  • 90% Pre-Assembled
  • Lattice Glass Platform
  • High Printing Speed With Three Axis Linkage
  • Resume Power Feature
  • New 32-Bit Motherboard
  • 24v PSU, 15A Power Supply
  • Titan Extruder
  • Wi-Fi Remote Control

All-Metal Structure

Metal 3D printers are definitely the preferred material when it comes to stability and precision on a large machine. You’re getting a high quality metal structure which gives you durability and safety for the machine. When done correctly, as the QQ-S is, you’re getting a sturdy 3D printer that you can rely on.

90% Pre-Assembled

Everyone loves things being simplified for you, so the assembly process isn’t much different. Once you receive your QQ-S, you’ll notice that most of it is already pre-assembled for you, requiring around 20 minutes to fully assemble the 3D printer.

Lattice Glass Platform

We shouldn’t overlook the importance of the print platform that your model will be built on. You’ll be receiving a surface called the Lattice Glass Platform which gives great adhesion for the initial print, and easy print removal after your print has cooled down.

This ceramic glass platform is well-loved by users of this 3D printer.

High Printing Speed With Three Axis Linkage

The three-axis linkage sounds pretty complex, but just know it’s what gives the QQ-S the ability to move fast for your printing desires. It has a well-developed structure which provides high speeds, up to 60% faster than some other types of printers.

Once you hit print on your 3D printer, seeing the speed at which this Delta 3D printer can work is serious business.

Resume Power Feature

No one likes the unlikely event of a power outage, but even worse is having one while in the middle of a 15 hour print! All we would need to counter this is the resume power feature, which the QQ-S so conveniently has. It means that when your power is accidentally cutoff from the 3D printer, the last printing position is committed to memory, so it can resume the print after turning on.

New 32-Bit Motherboard

Compared to the original QQ, the QQ-S has a nice new motherboard addition which improves the stepper response and positioning accuracy, for better overall quality and peace of mind.

24v PSU, 15A Power Supply

The accompanying power supply to this 3D printer contains the mosfet module which can keep the heated bed heating for long periods of time without issues. You can heat the bed to 100°C for 48 hours.

Titan Extruder

This extruder gives the ability to print flexible filament, with a good grip on the filament to guide it through the printer.

Wi-Fi Remote Control

You can smartly control the 3D printer through your phone with the Wi-Fi remote control feature.

Benefits of FLSUN QQ-S

  • Easy to assemble and setup, taking around 20 minutes
  • Auto-leveling is also easy to do, just make sure to clean and pre-heat the nozzle
  • Get great looking prints straight out the box without tinkering
  • Relatively quiet 3D printer so it doesn’t have to be a disturbance below 50dB
  • 32-bit controller gives a smoother printing experience
  • Ultrafast 3D printing speeds
  • Supports flexible filament
  • Cooling system increase lifespan of the 3D printer
  • Nice responsive touchscreen with simple icons
  • Each 3D printer factory-tested 48 hours before packing
  • Peace of mind with the power resume function
  • FLSUN Facebook group for support and assistance
  • Great packing on the 3D printer

Downsides of Simple FLSUN QQ-S

There have been some reports of the 3D printer coming in dusty, so make sure to give it a little clean inside and out. This could have been a transport or warehouse issue with the production and packing process, so I wouldn’t worry too much about this, as it can easily be corrected.

Make sure you correctly change the PSU voltage, where it will guide you in the instruction manual or you can run into problems. The switch for changing the voltage can be found after removing the bottom cover.

The color of the wiring has been known to be non-traditional which shouldn’t affect operation, but can be confusing when first seeing it. Instead of the usual green or yellow color for the Earth wire, it may be red.

There may be an issue with the wiring of the extruder stepper motor since it goes through the metal case in the assembly process. Unfortunately there isn’t a rubber grommet to stop it from rubbing against the metal, so you should try putting some type of insulating tape around the point of contact.

You might not be abler to upgrade to a dual extruder system unless you change the motherboard since the 32-bit MKS Robin Mini only has one extruder motor connection.

Customer Reviews

Many users love how the FLSUN QQ-S is a great 3D printer for a first time user, since it doesn’t take much to get it started and you can begin making high quality prints soon after assembly.

You’re not limited to just PLA like many 3D printers out there. Being able to expand your material usage from PLA to PETG to TPU is a great feature, along with the actual speed you are getting from this machine. Print quality does however increase when using slower speeds.

People have reported great customer service by FLSUN on their Skype chat and getting assistance from the official Facebook group.

It’s not uncommon to run into some kind of issue down the line, where one person had a failed part cooling fan and the bed wouldn’t level properly. They actually ended up sending them a replacement fan and glass bed, along with a firmware update.

This solution solved all their problems, giving a serious improvement to their 3D printing journey.

Rather than the bundle SD cards you get with other 3D printers, this one comes with a brand name SD card and a good amount of bundled PLA filament for your printing pleasure. You also get a few spares and tools as a gesture to keep things smooth.

It’s great for beginners, but even an engineer who had 3D printing experience was stunned at the quality and number of features provided at such a good cost. Users love the speed of the QQ-S and how it works very well with several types of filament.

One user did have a complaint about their bed leveling, how after one year the leveling process was coming to be a hassle. It resulted in some poor first layers, but there are definitely methods to fix this, like the review mentioned above.

The automatic bed leveling definitely helps out with this process, where most people have no issues with it.

Make sure not to put the calibration face plate the wrong way around like one person did, because it has a slightly sticky side which can stick to the build glass.

You have the freedom to make upgrades to your 3D printer.

Most people show their appreciation for this 3D printer, albeit with a few troubleshooting issues and whatnot. It has a rating of 4.1/5.0 which is pretty solid.


Whether you are a beginner or expert, the FLSUN QQ-S has shown its presence professionally, although it has had some blips along the way. With time and experience, things slowly develop and become better.

I think if you were to get yourself this 3D printer, you would love the features, speed and print quality along with the very competitive price and good build volume.

You can really show off your creativity with this 3D printer and proudly show off your prints to friends, family and impress yourself!
