With a build volume of 175 x 180 x 170 mm and print speeds of up to 500 mm/s , Qidi Tech's X-Smart 3 is one of the leading desktop high-speed FDM printers on the market! With all its features (Klipper compatibility, CoreXY structure, Qidi high-speed extruder) it is designed for fast printing with excellent quality!

CoreXY structure

The X-Smart 3's CoreXY structure reduces motion inertia to enable greater acceleration and speed.

Lightweight extruder, great performance

X-Smart 3 is equipped with a high-flow direct drive extruder that weighs just 600 g! With a gear ratio of 9.5:1, the extruder guarantees more stable and faster extrusion as well as smoother feeding and delivery of filaments.

64-bit Cortex-A53 processor

X-Smart 3 is equipped with an RK3328 quad-core Cortex-A53 64-bit processor with a core frequency of 1.5GHz. The powerful processor enables high-speed printing up to 500 mm/s, an acceleration of 20,000 mm/s² and guarantees a flow rate of 30 mm³/s!

Automatic levelling

Thanks to the smart automatic levelling over 16 points, the height of different points on the heat bed can be automatically equalised.

Long-lasting HF build plate

The scratch-resistant Qidi Tech HF build plate has a special coating for particularly good adhesion of the models. After the model is completely printed, the flexible plate can be bent slightly - the model will release itself. You can forget about problems like warping!

User-friendly QIDI slicer software

Thanks to a combination of normal mode and expert mode, the user-friendly QIDI Slicer software can be easily used by both beginners and true 3D printing connoisseurs!

Also compatible with other slicing software like Ultimaker Cura, Simplify3D, PrusaSlicer etc.

Other features:

  • TMC2209 quiet drive for less noise
  • 4.3 inch touchscreen (480x272)
  • Brass Nozzle Hotend with a ceramic heater
