| Extra features | The Longer LK4 is a versatile 3D printer capable of working with a wide range of filaments, such as PLA, ABS, TPU, copper, wood and carbon fiber, thanks to its 0.4mm nozzle and heated bed up to 110°C. With a printing accuracy of between 0.05-0.4mm, it stands out for its solid construction with an aluminum frame, weighing around 7kg, and a robust 24V and 15A power supply. The kit includes an Allen key, a 7/10 key, a microSD card with USB adapter, a spatula, cable ties, a power cable, 5m of filament and a spare filament end sensor. Assembly is simplified, with around 90% of the equipment pre-assembled, and detailed instructions assist in the process. Special features include print recovery after power failure, a filament end sensor, a super-adhesive printing surface and an intuitive color touchscreen display. The design features smooth profiles for easy assembly, and the position of the filament holder optimizes the filament path to the extruder. The LK4 is a solid choice for 3D printing enthusiasts looking for quality and versatility. | The Kingroon KP3S Pro V2 is a high-speed FDM 3D printer with Klipper firmware, ensuring fast and precise prints. It features linear rails on all axes, a Direct Drive extruder with a 9.5:1 gear ratio, and an efficient ceramic heater. It includes an inductive sensor for automatic bed leveling, a PEI magnetic bed, a built-in accelerometer for vibration calibration, and Wi-Fi, Ethernet, and USB connectivity for remote control. |

Conclusion |
| In comparing the Longer LK4 and Kingroon KP3S Pro V2 3D printers, both models offer similar print volumes and heated beds, making them compatible with a wide range of materials such as PLA and PETG. The LK4, launching in 2019, comes with several user-friendly features including a power loss recovery function, a filament end sensor, and an intuitive touchscreen interface. It is lightweight and has a robust construction, making it a compelling option for hobbyists and beginners looking for reliability and ease of use. On the other hand, the KP3S Pro V2, released in 2024, introduces advanced features such as automatic bed leveling and high printing speeds made possible by its Direct Drive extruder and Klipper firmware, appealing to users seeking speed and precision. However, it does lack some of the convenience features found in the LK4, such as a filament end sensor and power recovery. In terms of price, the LK4 offers a cost-effective solution, while the KP3S Pro V2, at a slightly higher price, aims to justify this with its newer technology and advanced features tailored for those who prioritize speed and automation. Ultimately, the choice between these two printers comes down to the user’s specific needs. The Longer LK4 is ideal for those who value basic functionality, ease of assembly, and reliability, while the Kingroon KP3S Pro V2 is better suited for users looking for advanced capabilities and faster print speeds. Both printers offer solid value within their price points, but potential buyers should align their choice with their printing priorities and experience level. |
