Intelligent Auto Leveling

With 16-point exact leveling, the unevenness of the hot bed is automatically compensated, deducting the hassle of manual leveling, and improves printing

Direct Dual-gear Extruder and Compatibility

Longer LK4 X features a direct dual-gear extruder with a 5:1 reduction ratio, stronger and more accurate filament control, and is compatible with PLA, TPU, ABS, PETG,and Wood.

32-Bit Open Source &  Ultra Silent Motherboard

A 32-Bit main control chip is outfitted with 4 kits of TMC2208 ultra-silent chipsets, printing fastly and quietly. With open-source firmware,  you have more creative freedom.

Strong adhesion & Simpe Removal of PEI Film

The platform is built of premium spring-flexible steel that allows for simple filament adhesion to the print bed without the use of adhesive. And simply removes the printed model by just removing the PEI sheet and slightly bending it.

Resume Printing & Run Out Protection

Longer LK4 X is equipped with a double resume printing function after filamentrun runs out or power is lost, algorithms record and detect the printing process in real time , saving both time and filament.

Easy Assembling

95% Pre-assembled, with only 6 steps to complete the assembly, reduces operation time and trouble, quickly starts printing. 

Large Touch Screen 

Longer LK4 X with a 4.3 inch full-color touch screen, you can say goodbye to the era of manual knobs and dot-matrix display, easy to operate.

Dual Fan Blower Kit

With dual blower kit, the filament can be cooled quickly after extrusion so that the model is not prone to deformation or wire drawing.

Low Power Consumptions

A building size of 8.66"*8.66"*9.84" (220x220x250mm) is sufficient for daily use, and lower power consumption reduces energy using.

Manual Belt Tensioners

The X/Y-Axis knob tensioners may easily and  timely adjust the belt's tension,  prevent layer shifting, enabling better printing.

Improved Teflon Tube 

The new teflon tube stand higher temperatures and not easy to clog inside the nozzle and will provide constant quality of printing.
