Flsun currently sells four 3D printers: the Super Racer, V400, QQ-S Pro, and Q5.

I’ve personally owned the Flsun QQ-S Pro at home, as well as spending a lot of time recently trying the Super Racer and V400.

In this article, I’ll run through the differences between each, to help you find which is the best Flsun 3D printer for you.

Flsun 3D Printers – A Quick Overview

Flsun’s 3D printers are all delta 3D printers rather than standard Cartesian 3D printers. Flsun delta printers are much faster due to their Bowden extruders and triangulation systems.

Even their cheapest models, the Flsun Q5 and QQ-S Pro, comfortably print at up to 120mm/s and 170mm/s, respectively. The Super Racer prints at 200mm/s, and the V400 up to 400mm/s.

Flsun printers are all beginner-friendly (they come 90% assembled), easy-to-use, and low-maintenance machines that will fit well into any workspace.

Flsun Q5


An impressive 3D printer for under $250.

Automatic bed leveling.


The most basic Flsun printer, with the slowest speed and smallest print volume.

The Flsun Q5 is a well-rounded, accessible machine ideal for beginners on a budget that can speedily print simple projects.

For under $300, the Flsun Q5 is an impressive 3D printer. With a large build volume and automatic bed leveling, it does exactly what you need as an easy-to-use first printer.

Large enough to handle some decently sized projects, and fast enough so as not to keep you waiting, the Q5 is a good choice for anyone who wants a good, high-quality FDM printer.

When to Buy the Flsun Q5

The Flsun Q5 is best if you’re on a tight budget and don’t need any fancy extras.

That’s not to say that the Q5 it’s basic, far from it. Few FDM printers offer this speed and quality at such a low price, especially with automatic bed leveling.

If you’re on a budget or simply have no need to pay extra for the size and speed of the QQ-S Pro and SR, then the Q5 is the Flsun 3D printer for you.

Flsun QQ-S Pro

  • Price: Check latest price at Flsun here
  • Build Volume: 255 x 360mm
  • Max Print Speed: Up to 300 mm/s (120 mm/s recommended)
  • Compatible Materials: PLA, ABS, and PETG
  • Connectivity: USB, SD Card, and Wi-Fi
  • Ideal For: Small Business Owners and Dedicated Enthusiasts
Flsun QQ-S Pro


Larger and faster than the FLSUN Q5.

Upgraded build volume and motherboard.

High max print speed, though it performs best at lower speeds.


The newer Flsun Super Racer eclipses it in most areas.

The simplest way to describe the Flsun QQ-S Pro is by saying it’s a larger, faster version of the Flsun Q5.

I bought mine in 2021, and it was one of my favorite 3D printers for a long time. It’s extremely easy to assemble (it took me 20 minutes), and the delta design means you can print quickly and print high-quality tall objects like figurines and vases.

With an upgraded build volume and 32-bit motherboard, the QQ-S Pro is ideal if you want to work on larger 3D printing projects, and don’t want to sacrifice detail for size. The higher print speed than the Q5 will suit you if you’re the impatient type.

This makes the Flsun QQ-S Pro the perfect machine if you’re looking for something a little bigger, or use your 3D printer to make money and need a faster turnover without diminishing your product quality.

While the maximum print speed of 300mm/s is a great feature, these high speeds tend to lead to less detailed prints. In this case, you’ll be happy to know that the Flsun QQ-S Pro still produces high-quality prints even at around 100mm/s. This is much faster than the average FDM printer in this price range.

However, if printing speed is your top priority, however, then you’re much better off looking at the Flsun Super Racer, one of the fastest FDM printers on the market at this price.

When to Buy the Flsun QQ-S Pro

The Flsun QQ-S Pro is ideal if you want a larger, faster delta printer but don’t want to spend more than $300. 

It’s fast, making it ideal if you print a lot of models, and don’t want to lose print quality by speeding things up too much. It’s larger and faster than the Q5, but still reasonably priced. Though, it’s not as fast as the SR or V400.

Flsun Super Racer

  • Price: Check latest price at Amazon here / Flsun here
  • Build Volume: 260 x 260 x 330mm
  • Max Print Speed: 200 mm/s (150 mm/s recommended)
  • Compatible Materials: PLA, ABS, and PETG
  • Connectivity: SD Card and USB
  • Ideal For: Enthusiasts who prize speed over Wi-Fi connectivity
Flsun Super Racer


One of the fastest FDM printers around.

Quiet operation: prints at under 50dB.


Smaller build area than the Flsun QQ-S Pro.

The Flsun Super Racer (SR for short) lives up to its name by being one of the fastest FDM printers around. At 200mm/s, you won’t be kept waiting around for long until your projects are ready.

The SR is also very quiet for a 3D printer of this caliber. At under 50dB, no louder than someone talking over a TV show, it won’t disturb even if you’re printing late at night in an apartment.

Whereas the QQ-S Pro keeps good print accuracy and surface finishes up to around 100mm/s, the Super Racer can print well at up to 150mm/s.

And while the build volume is slightly smaller, I have not found this impacted my projects very often, and the Super Racer very much feels like an upgrade on the Flsun QQ-S Pro.

When to Buy the Flsun Super Racer

Simply put, the Super Racer should be what you opt for if you value speed over anything else, but want something under $500.

While it has a slightly smaller build volume than the QQ-S on the XY planes, this is just a tiny amount.

But, for the extra print speed at up to 200mm/s, and generally improved quality, I think it’s well worth it.

Flsun V400

  • Price: Check latest price at Flsun here
  • Build Volume: ⌀300 x 410mm
  • Max Print Speed: 400 mm/s (200 mm/s recommended)
  • Compatible Materials: PLA, PLA+, ABS, PETG, Wood, TPU, Nylon, and PC
  • Connectivity: Wi-fi and U disk
  • Ideal For: Printing large projects very quickly
Flsun V400


Very large build volume

Fastest 3D printer in the Flsun range

High material compatibility


Expensive compared to other Flsun printers

Very tall height can be cumbersome for lower workspaces

The Flsun V400 model is considered the premium 3D printer of the range. The build area is a massive ⌀300 x410mm, making it perfect for larger projects. The impressive max print speed of 400mm/s prints in half the time of the Super Racer.

The linear guide is very cleverly designed and reduces noise, making the V400 relatively quiet. The frame has also been designed for sturdiness and strength, preventing too much vibration and printing accurate parts with good surface finishes (also helped by the direct drive extruders). The powerful cooling fan is also a nice upgrade.

However, its high cost may be a dealbreaker for you. The Flsun V400 sells for $849 on Flsun’s official site, more than twice the Super Racer’s price.

The Flsun V400’s height may also be an issue for those of you with limited workspace. It stands at around 45 inches (3.75ft) when you including the spool holder, which, if set on a raised surface, might be hard to fit on your desktop.

When to Buy the Flsun V400

The Flsun V400 is the best Flsun 3D printer for you if you have the budget, and prioritize speed and size. It’s also ideal if you want to print TPU and flexibles with the better retraction offered by the direct drive extruder.
