The Top 6 Best CoreXY 3D Printers of 2021

Known for speed and precision, CoreXY 3D printers are some of the most powerful (and affordable) FDM printers.

With FDM 3D printers largely accounting for the multi-billion dollar growth in the 3D printer market, it’s safe to assume that the CoreXY 3D printing system is reaping the benefits of this attention.

But how do they differ from standard FDM builds?

Aside from their speed and precision, CoreXY printers employ an innovative design consisting of belts that control the printer head (and in some cases even printer beds!), giving them productivity-boosting features like a stationary gantry system and motorized X and Y axes.

If you’re ready to take a deep dive into the best CoreXY 3D printer kits, then keep reading as we explore the technology behind CoreXY printers, their advantages, disadvantages, and take a look at the top CoreXY 3D printers on the market and who they work for best!

What is a CoreXY 3D Printer?

If you’re looking to invest in an FDM 3D printer, the most popular style is a Cartesian printer, and it’s within that subset we find the CoreXY system. Now, CoreXY is technically a form of Cartesian 3D printer, but you’ll often find comparisons of the two and that’s because of CoreXY’s unique design.

For more info: read our guide to the 4 main types of FDM printers.

CoreXY is a 3D printing system that was developed by an MIT engineer in 2013. These printers are typically cube-shaped and consist of belts that operate using stepper motors to move the printer head along the X and Y axes. In this case, the printer head is the only object actually moving with any significant speed.

While the printer head moves along the X and Y-axis, the printer bed moves along the Z, and all of these combine to 3D print the model.

This is compared to standard Cartesian printing systems, which are similar as the printer bed moves along the Z-axis, whilst the printer head moves along the X and Y. However, the difference is the printer head is connected to the gantry system, not belts. This means the entire gantry is moving with the printer head, as opposed to just the printer head moving.

With CoreXY 3D printing systems, there’s less opportunity for the gantry system to move. This decreases the chance of excess vibration, which if you’ve ever used a 3D printer before you know too much vibration can lead to side effects like ringing and ghosting. This isn’t to say it never happens, but it’s less likely to.

Higher-end CoreXY models also often come with enclosures made from a variety of materials like plastics, acrylics, and fiberglass. This helps regulate the temperature when printing your models.

The overall result of this technology is increased space efficiency, speed, stability, and accuracy.

CoreXY 3D Printer Advantages vs Disadvantages

Advantages

  • Faster print speeds.
  • More affordable than other 3D printers.
  • Despite higher speeds, it can still deliver accurate and precise models.
  • A vertical moving printer bed means it can deliver the same build volume but in a more compact size.

Disadvantages

  • The belt system can be finicky, if the tension is too high or too low it can lead to increased wear and malfunctions.
  • If the printer’s frame isn’t assembled and lined up correctly it will lack accuracy, and the frame can shift over time.

The Best CoreXY 3D Printers

Understanding what CoreXY printers are is only half the battle, now it’s time to compare. Ranking from lowest to the highest price, here are our top CoreXY 3D printers.

1. Tronxy X5SA
