The 6 Best 3D Printers with Klipper Firmware

The Neptune 4 Pro is Elegoo’s entry into the Klipper world. It’s beginner-friendly, prints fast, and comes with various useful features that are sure to impress new users.

To begin, the 4 Pro has a segmented heated bed that allows you to heat either the center or the whole bed at once. This not only saves energy but also reduces your waiting times.

Another plus is the all-metal hot end on the 4 Pro. It heats up to 300 °C and lets you print with materials like PC, Nylon, and carbon fiber composites. Along with the usual PLA, ABS, and PETG, of course. This broad material compatibility means you can take on a wider variety of projects.

The printer’s automatic bed leveling is another feature that we appreciate. It measures the bed height on an 11×11 grid and automatically adjusts for unevenness in the print surface that would otherwise affect your first layers.

One downside is that the cooling system on the Neptune 4 Pro is noisy because of its strength. The X-axis bar’s blower arrangement uses several fans to speed up print cooling, but they can be quite disturbing when you sit alongside the printer.

Overall, the Neptune 4 Pro is an excellent package. With its useful features and impressive print speeds, this $300 printer provides great value for your money. We consider it to be the overall best Klipper 3D printer if you simply want to get started with the firmware and don’t need any fancy bells or whistles.

The QIDI Tech X-Max 3 is for users who need to print large objects quickly with various engineering materials. This printer is equipped with everything you need for a speedy and professional 3D printing experience.

For instance, you get a large, fully enclosed print volume of 325 x 325 x 315 mm. This entire build area is actively heated and can maintain ambient temperatures of up to 65°C. If you’re looking for warp-free prints in ABS, Nylon, or other high-temperature filaments, the X-Max 3 has what you need.

Additionally, the hot end reaches temperatures of up to 350°C. It comes with both copper alloy and hardened steel nozzles. These let you print standard materials, but also abrasive ones. For example, carbon fiber-filled, glow-in-the-dark, and wood filaments.

The X-Max 3 is powered by Klipper, which enables fast printing speeds of up to 600 mm/s with 20000 mm/s² of printer acceleration. In simple words, this printer is fast and significantly cuts down your printing times.

QIDI Tech could benefit from changing the placement of the dry box, which is located on the back and can be difficult to access. We faced the same issue in our review of the X-Plus 3; the smaller-sized sibling of this printer.

Overall, the X-Max 3 is one of the best 3D printers with Klipper we’ve come across. If you need to 3D print functional parts or engineering prototypes, its approximate $1000 price is money well spent on this machine.

The Elegoo Neptune 4 is the baseline version of the Neptune 4 series. It provides excellent value for its price and offers many features that are similar to its Pro counterpart.

Equipped with an all-metal hot end reaching up to 300 °C, the Neptune 4 can 3D print high-temperature filaments such as Nylon, PC, and ABS. It is recommended to use an enclosure for printing these temperature-sensitive materials.

With its listed maximum print speed of up to 500 mm/s, the Neptune 4 can help you cut down your print times by a lot. Keep in mind that with most filaments, the true print speeds will be much lower, but still plenty fast.

Like most 3D printers in this list, the Neptune 4 uses Klipper’s input shaping and pressure advance features, which help you reduce print issues that occur while printing at such fast speeds.

Additionally, the automatic bed leveling system is the same as that on the Neptune 4 Pro and helps ensure a smooth first layer. The 3D printer also has a large touchscreen that’s connected to the machine using a spiral cord. It allows you to take the control panel outside of an enclosure and place it somewhere more convenient.

It’s worth noting that the Neptune 4 utilizes a V-wheel assembly instead of the metal guide rails found in the 4 Pro version. This increases the maintenance of the 3D printer and decreases its accuracy somewhat. Additionally, it lacks the segmented heated bed function of the Pro model.

Both are relatively minor issues, but worth keeping in mind when choosing between the Neptune 4 or the 4 Pro version.

In summary, the Neptune 4 is an excellent budget Klipper 3D printer. It’s fast, affordable, and easy to use. This makes it an excellent choice for beginners, schools, or anyone else who wants to experience the magic of Klipper without breaking the bank.

The Sovol SV07 Plus can be considered a large 3D printer. With its 300 x 300 x 350 mm build volume, it is one of the biggest Klipper printers that you can find today.

A large print size like this comes in handy to print big models. Cosplay parts, large prototypes, architectural models, and busts, you can print them in a single piece.

With Klipper at its core, the SV07 Plus can do this impressively fast as well. The bigger your 3D prints, the more time you save by switching to a Klipper 3D printer. When you can shave half a day off your print time at once, that’s a big deal.

To ensure the filament flows smoothly, Sovol has installed a Volcano-style high-temperature hot end on the printer. Even at higher print speeds, it has enough power to provide you with the molten filament you need. And because it can reach temperatures up to 300 °C, the SV07 Plus also allows you to 3D print higher-performance plastics.

We’ve reviewed the Sovol SV07 in our workshop, we found it to be an overall decent 3D printer. However, the flaws we found in our testing, such as the poor quality control, loud cooling fans, and overly ambitious acceleration settings, have been carried forward to the Plus model as well.

That said, for under $400, no other printer comes as close to the Sovol SV07 Plus in terms of build volume and features. The Klipper integration is excellent, and if you want the extra build space and fast print speeds on a budget, this printer hits the mark. Just make sure you don’t mind tinkering with it, if necessary.

Creality’s K1 3D printer is one of their flagship offerings and a direct contender to the popular Bambu Lab 3D printers. With fast print speeds, enclosed design, and affordable price tag, the K1 gives you a better return on your money than its competitors.

In our Creality K1 review, we found it to be an excellent Klipper 3D printer. The print quality stood out the most to us, and we had no major issues even when pushing the machine to its limits.

Its enclosed build volume comes in handy for printing temperature-sensitive filaments like ABS and Nylon, which are more prone to warping. The enclosure gives the printer an industrial look while also helping to maintain a warm ambient temperature in the build space.

Its strain gauge bed leveling system is also well-implemented. In our print quality tests, the first layer was spot on almost every time, without even having to configure the Z-offset. The triple-lead screw system is also quite useful and helps to keep the bed stable at high speeds.

One thing to note is that although the K1 uses a custom version of Klipper firmware. It’s not easy to make changes to it. To access Klipper’s advanced features, you would need to manually flash the Klipper image and root your printer.

Based on our experience with the K1, we can attest that it is an incredibly fast 3D printer. The print quality is great at high speeds, and the printer as a whole delivers good value at around $500.

Voron printers are no-nonsense 3D printers that are designed to deliver peak 3D printing performance. They follow a basic structure but are otherwise fully customizable and often come in kits. The Voron 2.4 R2 is packed with an excellent set of features and is one of the best 3D printer kits you can get today.

Featuring a CoreXY design, the Voron 2.4 guarantees stability even at high speeds. It uses linear rails on the X and Y axes, while the Z axes are entirely supported via a belt system. This allows for rates of up to 600 mm/s without significantly affecting the print quality.

The Voron 2.4 R2 uses a combination of the Octopus Pro motherboard and a BTT Pi board to run Klipper. These chips are powerful enough to run all of Klipper’s features and allow you to add additional hardware elements if you wish. For example, you can configure additional microcontrollers and use an accelerometer to set the Input Shaping on the printer.

On top of that, this particular kit includes a Phaetus Dragon high-flow hotend. This hot end can reach temperatures up to 450 °C and push out filament at high rates. This allows you to print engineering materials like PEEK and Ultem that you can print with the other Klipper 3D printers in this list.

For under $1000, the printer offers a lot more than its competitors, provided that you’re willing to assemble and configure it yourself. If you have the patience and need a machine that can print practically anything you throw at it, the Voron 2.4 is the perfect choice for you.
