| Extra features | The FLSUN S1 Pro is a high-speed Delta 3D printer, reaching up to 1200 mm/s with 40,000 mm/s² acceleration. It features a build volume of 320 mm (diameter) x 430 mm (height), a 350°C hotend, dual-zone heated bed up to 120°C, a 50°C heated chamber, and an active filament drying holder. It includes a camera for remote monitoring, integrated UPS for power-loss safety, a HEPA filter, and a 7 touchscreen interface. Perfect for large and complex projects. | 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. |

Conclusion |
| In comparing the FLSUN S1 Pro and the Longer 3D LK4, it becomes evident that both printers cater to different user needs and budgets, offering unique advantages that can influence the purchasing decision. The FLSUN S1 Pro, released in 2024, stands out for its high speed and large print volume, making it ideal for professional users and enthusiasts who require the capacity to produce larger and more complex prints quickly. With advanced features such as automatic bed leveling, a direct drive system, a sophisticated touchscreen interface, and enhanced connectivity options, it is a high-performance machine that justifies its higher price point. Its enclosed design, coupled with power-loss recovery and active filament drying, adds to its reliability for demanding tasks and diverse material compatibility. In contrast, the Longer 3D LK4, while more affordable and lightweight, is a well-rounded option for hobbyists and beginners. Its robust construction, versatility in filament compatibility, and good print quality make it a solid choice for those new to 3D printing. The manual bed leveling and Bowden extruder system may require a bit more hands-on involvement, but its simplified assembly process and subsequent cost-effectiveness make it attractive for casual users or those exploring 3D printing without a significant financial commitment. In conclusion, the choice between the FLSUN S1 Pro and the Longer 3D LK4 largely depends on the user's priorities. For those seeking a high-performance, feature-rich printer capable of handling demanding projects, the S1 Pro is the superior option. However, for those who are budget-conscious and looking for a reliable and versatile entry-level printer, the LK4 offers an excellent balance of performance and affordability. |
