3D Printer Linear Rail

Advantages of Linear Rails 3D Printers

A linear rail contains a stiff steel rail and a sliding carriage with recirculating ball bearings to provide contact points between the carriage and the rail. This combination ensures a smooth and accurate motion for a linear rail 3D printer’s axis. Compared with 3D printers using linear rods or V-slot rollers, linear rails bring a lot of f advantages to the printer.

Linear rail is more reliable and stiffer.

Due to the shape and the stiffness of the metal, linear rails 3D printers have much less flex on the axis which greatly reduces backlash and ensures stiffer and more reliable operation for the printer.

Linear rails are simpler and lighter than linear rods.

Only one linear rail is needed for your 3D printer axis but at least two linear rods are needed to prevent the carriage from rotating. This advantage also means less 3D printing ringing would happen on linear rail 3D printers.

Linear rails are easier to install and much less maintenance is needed.

With regular mounting holes on both the rail and the carriage, you’re able to precisely install the linear rails with some bolts. Frankly, to say, linear rails offer 3D printers a smoother and more precise motion on their axis, hence a more reliable 3D printing with better printing quality.

Popular Linear Rail 3D Printers You Should Know

There are a few budget 3D printers using linear rails on the market. Here are some popular linear rail 3D printers you should know, for example, the Kingroon KP3S, KP5L, and KP3S Pro, Tiertime's Cetus MK3, UP Mini 2, and Cetus2, the Prusa's Prusa XL, the Markforged Mark Two, and the E3D Toolchanger, and the VORON's DIY 3D printers Voron 2.4, Switchwire, etc. Also you can upgrade the Creality Ender 3, CR10 3D printers with linear rails here in this page.
