PROS
  • Auto-bed leveling.
  • Amazing print speed.
  • Extraordinary print quality.
  • Considerable build volume.
  • Titan extruder.
  • 32- bit motherboard.
CONS
  • The non-moving print head makes it difficult to make certain intricate parts and functional prototypes.

If there is one attribute that this 3D printer can be associated to be mainly designed for that is, speed! FLSUN QQ-S Pro prints at 1.5 times the speed of the I3 structure printer managing no change in the accuracy.

The printer relies on high-speed products and high-quality services. You can print with print speeds ranging from 50 to 120 millimeters per second and yet the printer manages to give you the printing layer thickness of 0.15 mm.

Let’s look at the various aspects of this amazing 3D printer to find out how does it manage to balance such a high 3D printing speed without losing out on its accuracy of printing parts and functional prototypes.

Features

The most eccentric part about FLSUN QQ-S Pro is its flexible three-axis linkage system, powerful 32-bit motherboard, a 24 Volts power supply, lattice hotbed, and all-metal side shell that ensures better printing quality and a more stable structure. Some of the most exciting features of this 3D printer are mentioned below.

Lattice Bed

This is promoted a lot by the printer manufacturer as a high-strength lattice composite coating that allows fast heating; the characteristics that you need to increase your overall print speed.

Additionally, you also get very few warping issues to deal with while printing with 3D printing materials like ABS.

Moreover, having a lattice 3D print bed also means that there’d hardly be any bed adhesion issues in FLSUN QQ-S Pro during the printing or after the part is 3D printed and it is time to take it off the bed. And this is something that will make you relate to Anycubic Ultrabase.

There is a huge demand of high-tech glass bed because it releases prints in the coolest manner one can ever imagine to take off the part or functional prototype from the print bed.

You would not need any scrapers, hairspray, glue sticks, and mess while removing the prints from the bed.

Also according to the manufacturer, the print bed reaches up to 100 degrees Celsius in less than five minutes, this would allow you to print the most common filaments without almost any problems, speedily.

Like all other typical Delta 3D printers, this one too has a fixed, nonmoving, printing bed that needs to be leveled only once which makes it pretty feasible if you are going to 3D print for the first time.

Titan Extruder

Another feature promoted by the manufacturer is the all-new titan extruder inside the QQ-S pro 3D printer. At first glance, the extruder looks like the E3D Titan. But the exact detail of the extruder isn’t available.

However, it does look like an efficient design selection for the smooth feeding of filament. At least, the results specify the same.

It is equipped with a 0.4 mm extrusion nozzle but it can also hold 0.3 and  0.2 mm nozzles when you need finer prints than what you get by using a 0.4 mm one.

The extruder is capable of withstanding 270 degrees Celsius temperature at max, which means that printing with ABS, PLA, PVA, and wood would be a piece of cake.

Not only that but also printing with HIPS and flexible filaments with support materials would be possible.

32-bit motherboard

The Chinese manufacturer has kept the brain of this 3D printer operating on an eight-bit Arduino Mega 2560.

It is equipped with orchestrating components such as the extruder, the heated bed, motors, and sensors. The more power you have, the smoother the 3D printer operates.

The 32-bit motherboard allows you to stably print and manufacture even at high-temperature ranges and high printing speeds.

The printer is equipped with a touchscreen and Wi-fi connection. It can resume printing from the same condition where you had to stop because of the power cut off.

FLSUN QQ-S pro is equipped with filament detection, and turns-off automatically after the completion of 3D printing a part or functional prototypes. These qualities make it a perfect 3D printer for use at offices and at homes.

Full metal frame and quiet printing

FLSUN QQ-S Pro is fully made of stainless steel which permits very little wobbling and therefore more accurate 3D printing.

Even when you are building a part or functional prototype that has the build volume equivalent to the maximum that this 3D printer can offer it does not vibrate or anything. Even if you are 3D printing at a very fast print speed, it manages to stay stable.

According to the manufacturer, the QQ-S pro has an operating noise of fewer than 50 decibels which makes it suitable for your offices and homes.

However, there is no enclosed printing chamber depending on the 3D printing materials that you are using for printing parts or functional prototypes. So, at times you will need to watch out for toxic fumes. But, that’s manageable!

First Impressions

FLSUN QQ-S Pro 3D printer

If you have ever encountered a Delta 3D printer, maybe offering a lesser or more build volume than FLSUN QQ-S Pro, you’d be able to relate to the design of this printer. That’s the peculiarity of Delta 3D printers, they are all the same in design.

The typical triangular shape formation using three connected strands that have rails over them which allow for the nozzle system movement to the print bed of the printer and back! The full-color touchscreen interface of this 3D printer is present at the bottom of the body of this 3D printer just beside the power button.

The touchscreen interface will let you operate and control most of the functions that you can do on FLSUN QQ-S Pro, like pre-heat, move, print, extrude, level, set some of the aspects of this 3D printer, and a lot more.

Setup

The printer is pretty much plug-and-play. There is an instruction manual that you must go through before starting with your first 3D print.

Doing so would make you familiar with some typical nuances that this 3D printer carries and which differentiates it from other 3D printers.

Once you are done with that, install the SD card or connect to the 3D printer using a USB cord and install the sliced file that contains the geometry of the part or functional prototype that you wish to 3D print in G or GCODES so it is fed to the 3D printer.

After this is done, auto-level the bed accordingly before starting to 3D print. All of this can take approximately 10 to 15 minutes of your time and then you are good to go.

Printing Type/Cost

The basis of 3D printing a part or functional prototype using FLSUN QQ-S Pro FDM 3D printing technology!

The complete process starts with a solid filament, any one of the above-mentioned ones is what you can use to print with this 3D printer.

You need to fit that filament in the filament spool that’s present on the head of this 3D printer. The printing process actively starts after loading the 3D printer filament.

It is brought to its glass transition temperature in the extrusion chamber, after which the 3D printer filament is allowed to flow on the print bed using the nozzle system.

The first layer of 3D printer filament is laid down on the print bed according to the geometry of the part or functional prototype that’s fed to the printer.

And then the nozzle moves 0.15 mm above the first layer to print another one. And the same process is repeated until you get the complete part or functional prototype.

The cost of printing a single part or functional prototype using this process is generally low. However, it depends on the geometry of the part, the 3D printer filament used in production, the amount of infill used in it, the support structures, and a lot more.
