Kingroon KP3S Pro is a cantilever-style 3D printer with linear guide rails on both X and Z-axis to enhance printer head stability and accuracy for increased printing quality.     

Based on a titan direct drive extruder with a 3:1 gear ratio, Kingroon KP3S Pro is able to print various 3D printing materials, including commonly used PLA, flexible materials like TPU and PETG.  
Compared with KP3S, KP3S Pro has an increased print volume of 200*200*200mm, which further expands the printer's capability for your daily 3D printing tasks.
With TMC2225 stepper drivers, all motors on KP3S Pro operate quietly. A quiet printing is certainly a plus for not disturbing your family.
With a built-in switching power supply, KP3S Pro operates much safer and offers more convenience to be placed when compared with 3D printers having independent switching power supplies.


  • Compact design but a decent print volume of 200*200*200mm. (print bed is 210*210mm size)
  • Reliable titan direct extruder with 3:1 gear ratio.
  • Build-in switching power supply.
  • Resume printing when unexpected power failure or filament outage happens.
  • TMC2225 stepper driver ensured quiet printing.
  • Enhanced accuracy by X and Z-axis linear guide rails.
  • Stable print bed operation with larger support underneath.
  • 95% pre-assembled for about 15 minutes of quick installation.

Y-Axis Upgrade NOTE: 

The printing height would be decreased to 180-185mm after installing the Y-axis linear rail upgrade kit.

Very good printee

It works fantastic, but dont’t set the speed to more than the recommended, tried setting the speed to 100 and the printer bed exploded off twice:D

Perfect prints, waited for too long

Excellent printer for the price, perfect print quality from first print, nice glass bed
So far the best printer I had
waited more then 3 months for the delivery

Great printer, bad service

Everything about Kingroon's printer is great and cheap but their service is really bad. I spent almost 2 months to get my order and they didn't give me almost any info.
Their PLA is great too.
