QIDI X-Smart 3 Review 3

Instead of the usual PLA filament, QIDI ships the X-Smart 3 with ABS filament. I also love that they included the glue stick and Ethernet cable in the package.

Printer Setup

Setting up the QIDI X-Smart 3 is easy and. It took us about 10 minutes to get started with it. The 3D printer is shipped 95% pre-assembled. Therefore, there isn’t much to do for the setup process—just a few minor tasks like removing some tie wraps.

QIDI X-Smart 3 Review 4

The tie wraps hold the components in place and safe during shipping. You also have to remove a couple of screws that hold the Z-axis components in place.

To help you get started, there is a manual with setup instructions. The instructions are also available on the machine once you switch it on.

QIDI X-Smart 3 Review 5

After switching the QIDI X-Smart 3 on, you’ll be guided through the setup process on the screen. The setup instructions cover everything, from leveling the bed to running Input Shaper and cleaning the carbon fiber rods.

Overall, setting up and getting the X-Smart 3 is easy, even for beginners.

QIDI X-Smart 3 Features

Now let’s take a look of some notable features of the X-Smart 3.

Hot End Temperature

To melt the filament, the printer uses a compact all-metal hot end that can reach temperatures of up to 280°C. This high temperature means you can print with a wide range of materials, including polycarbonate, nylon, and more.

QIDI X-Smart 3 Review 6

However, the printbed only reaches a maximum of 120°C. Therefore, it won’t be possible to print some high-temperature materials with this unit.

Compared to some 3D printers we’ve reviewed in the past, the X-Smart 3’s hot end heatsink is relatively small. However, we haven’t encountered any issues, such as extrusion problems or heat creep, with it.

The hotend has a circular heater cartridge, which helps distribute heat more evenly.

QIDI X-Smart 3 Review 7

The X-Smart 3 boasts of one of the fastest heat-up times we’ve seen so far. When you want to quickly swap filaments, the hot end will be ready for you in no time. The part provides ample power for the fast filament feed rates of the X-Smart 3, ensuring efficient and smooth printing.

So far, the hot end of the QIDI X-Smart 3 has performed remarkably well. We’ve tested it with various filaments. All the filaments printed without any major issues.

Geared Extruder

The X-Smart 3 has a powerful 9.5:1 geared extruder in its print head. This extruder efficiently pushes filament at high print speeds. At the same time, it provides the necessary torque required for printing with more abrasive filaments. The geared extruder is central to the unit’s impressive performance.

QIDI X-Smart 3 Review 8

Instead of the typical NEMA17 stepper motor, the X-Smart 3 uses a compact pancake stepper motor that fits perfectly between the carbon fiber X-axis rods. The print head is lightweight and well-balanced. This means reduced shaking during the printing process, faster print speeds and good quality prints.

The gears in the extruder are a combination of metal and plastic. Depending on the type of filament you use, the gears may wear out slightly faster than expected. However, we haven’t encountered any issues at this time regarding this.

Powerful Print Cooling

The QIDI X-Smart 3 has impressive cooling. The print head features a 50×15 mm radial fan, which performs better than the typical 40×10 mm fans found in other printers.

Inside the enclosure, a large blower fan draws air from the bottom of the chamber and directs it through a wide opening placed at nozzle height.

The result?

A generous stream of air that’s delivered precisely to the freshly extruded filament. This cooling feature is a real game-changer when it comes to handling overhangs, bridging, and overall faster printing.

This cooling system is useful for low-temperature filaments like PLA and TPU, which are not prone to warping or delamination when exposed to airflow. If you mostly work with higher-temperature filaments, you can switch off the fan since you won’t be needing it.

The fan can be quite loud. However, since the QIDI X-Smart 3 is already a rather noisy 3D printer, the fan noise doesn’t stand out too much.

The print cooling capabilities of the QIDI X-Smart 3 are impressive, providing excellent performance for low-temperature filaments. Just keep in mind the noise level and filament compatibility when deciding whether to use the print cooling fan.

Carbon Fiber Rods

The QIDI X-Smart 3 has carbon fiber rods. For a 3D printer to print fast, it has to be light. These rods keep the unit light.

Carbon fiber rods have some advantages over the typical stainless steel ones. First, they are lighter, and second, they are stiffer. Therefore, you can print at higher speeds while minimizing issues like ringing and other unwanted artifacts in your prints.

The printer’s carbon fiber rods measure 10 mm in diameter. The rods are securely attached to the Y-axis carriages with epoxy. The rods are not replaceable if damaged. Therefore, handle them with care to prevent scratches.

Unlike standard stainless steel rods, the carbon fiber rods on this printer do not require any lubrication. The X-carriage uses bushings instead of bearings. Therefore, keep the rods dry.

To maintain their cleanliness, wipe the rods down with isopropyl alcohol every 1-2 weeks or whenever they get dusty.

Overall, the carbon fiber rods contribute to X-Smart’s impressive printing capabilities.

Flexible Print Surface

The QIDI X-Smart 3 3D printer has a flexible magnetic sheet that sticks to the heated bed. In theory, it’s a convenient solution as it allows for easy removal of finished prints. However, in practice, we found that the surface doesn’t adhere that well with certain filaments.

For example, we encountered issues with one particular color of PLA and one type of PETG, where the adhesion wasn’t as expected. This was despite having a properly set Z-offset, a leveled bed, and using filaments that work well with other machines.

To solve this issue, we applied a thin layer of glue stick to the print surface. By the way, there is a small glue stick in the box, which I think was put there solely to address this issue.

On the positive side, all the other filaments we tested, such as ABS, PETG, PC-FR, and PA12-CF, adhered perfectly without the need for any bed adhesive. We didn’t even require a raft or brim for those prints.

The print bed is double-sided, but both sides are PC-coated. Unfortunately, this means you can’t use different sides for different filaments. However, having the other side as a backup is still a plus.

Ideally, we would have preferred to see at least one of the surfaces PEI-coated. A high-quality PEI coating offers better adhesion than the current surface and would work with a wider range of filaments without relying on a glue stick.

The alignment tabs located at the back of the print bed are thoughtful. When putting the printbed back in place after removing a print, the tabs help with alignment. the tabs make aligning the print bed easy

The paint on the print surface tends to come off at higher temperatures. However, since the paint is only applied to the corners, its coming off won’t impact the quality of your prints.

Temperature Uniformity

The printbed of the X-Smart 3 3D printer is heated evenly. We consistently achieved even temperatures across the entire bed, regardless of the temperature range.

The printbed doesn’t have any insulation underneath but still performed exceptionally well. While the printer’s enclosure helps to keep the temperature even, credit should also be given to the thoughtful design of the bed PCB traces.

Heating Time

The QIDI X-Smart 3’s bed takes some time to heat. The 175 x 180 mm print bed area is quite large. Therefore, it requires a lot of power to heat up.

For this review, we did our tests with the enclosure door closed and the top off, which is similar to the conditions when printing PLA or TPU.

If you close the top of the printer and enable the heated chamber, the heating time reduces

Heated Chamber

The heated chamber ensures a consistent temperature inside the enclosure. This helps to reduce warping and delamination when printing with high-temperature materials like ABS and nylon.

Inside the chamber is a heating element and fan that evenly heat and circulate air respectively. The chamber produces some noise when the printer is working.

TIP: Avoid printing low-temperature filaments like PLA in the heated chamber, as it can lead to issues such as sagging and elephant’s foot.

The heated chamber requires a separate power supply from the one that the printer uses. This increases electricity consumption. When running at full power, the chamber alone draws around 350W.

Automatic Bed Leveling

QIDI X-Smart 3 Review 11

The QIDI X-Smart 3 has an automatic bed leveling (ABL) sensor, which helps the printer’s firmware compensate for any unevenness on the print bed. The sensor is a capacitive probe that detects the metal print surface.

The sensor works well with the provided print bed. However, it cannot be used with a glass bed. Keep this in mind if you prefer using a glass bed for your prints.

The automatic bed leveling process takes some time since the sensor scans 16 points on the bed. However, after the bed is leveled, you won’t need to run the bed leveling again before every print.

The automatic bed leveling system ensures that your prints adhere properly to the bed for more consistent and reliable prints.

Touchscreen

QIDI X-Smart 3 Review 12

The X-Smart 3D printer is operated through a 4.3-inch touchscreen, which is conveniently positioned at the top of the machine. The screen is user-friendly and easy to use. However, You’ll need to apply some bit of pressure on the screen for a click to register.

User Interface

QIDI X-Smart 3 Review 13

The user interface of the QIDI X-Smart 3 is designed with beginners in mind. As a result, it may not fully meet the needs of advanced users as it lacks some advanced settings.

Advanced users might need to use GCode for detailed customization. For example, on the menu, you cannot adjust critical parameters such as stepper motor current, acceleration, jerk settings, and others. You cannot also change Klipper settings, like pressure advance, through the UI. While the UI allows initiating the Input Shaper calibration sequence, it lacks further adjustments.

QIDI X-Smart 3 Review 14

You may also encounter occasional inaccuracies in translated text within the interface.

Overall, while the UI is well-organized and accessible, it has some limitations and some rough edges. These limitations, though not major issues, could be addressed in future firmware updates by QIDI.

Build Quality and Construction

Now let’s check out the build quality of the X-Smart printer.

Build Volume

The X-Smart offers a spacious print area of 175x180x170mm.

QIDI X-Smart 3 Review 15

The enclosure makes this 3D printer notably larger than open-frame machines. When considering a spot for it, keep in mind that you’ll need approximately 37×36 cm of space on your 3D printer table just for the machine itself.

Moreover, factor in the space needed in the front to open the front panel door, space at the rear for changing spools, and possibly room above the machine to remove the top lid.

Full Enclosure

The QIDI X-Smart is fully enclosed. Therefore, you can use high-temperature filaments without worrying about your creations getting messed up or bent.

The printer also has a removable top cover. For materials like PLA or TPU that work at lower temperatures, you can open the lid to cool down the plastic you’ve just printed more quickly.

QIDI X-Smart 3 Review 16

However, one drawback is that this enclosure doesn’t have a way to clean the air. So, the smell from the printer might escape, and you might notice it. However, the smell is not as strong as in printers that are (partially) open, but it’s still there.

CoreXY Kinematics

QIDI X-Smart 3 Review 17

The QIDI X-Smart 3 uses a CoreXY setup, allowing for swift printing speeds.

In CoreXY 3D printers, the X and Y stepper motors are firmly placed on the frame. This design reduces the overall weight that needs to move during printing. As a result, you end up with faster and more efficient movements.

Interestingly, some 3D printer models, such as the Ender 5 S1, aimed at achieving high print speeds but failed to implement CoreXY kinematics.

The X-Smart 3 also comes fully assembled, unlike many prior CoreXY 3D printers that required assembly from a kit. This preassembly is particularly beneficial for beginners in 3D printing as it saves them from the potential challenge of assembling the printer from scratch.

Pros

  • Prints quite fast
  • Can handle a wide range of filaments
  • CoreXY mechanics
  • Fast print cooling
  • Has practical features
  • Fully enclosed
  • Stock Klipper firmware

Cons

  • The printer is quite loud than modern 3D printers
  • Bed adhesion is not the best
  • The carbon fiber rods require extra care
  • Does not have an air filter

While this printer has a plastic exterior, it’s performance cannot be denied. The overall build quality has room for improvement but we love how the unit can print almost any type of filament. As a result, this printer is our workshop’s current workhorse for a wide range of print jobs.

Should you get the QIDI X-Smart 3D Printer?

Yes, if you want a 3D printer that can handle different materials like PLA, PC, and Nylon, the QIDI X-Smart 3D printer is a great choice. It’s good for making things with those materials.

It’s good because it can use different filaments, it can make big things, and it has cool features, all without being too expensive.

The best things about it are that it can handle high heat, it cools down prints well, and it prints fast.

However, there are some things that could be better. The way it’s made could be improved, and changing filaments or hot ends takes more time than we’d like.

But overall, for the price of under $500, it’s hard to find a better deal. If you really like 3D printing, we suggest you get this printer for your home or workshop.
