Extra features	Elegoo Mars 5 features a 6.6” 4K monochrome LCD screen and 35um XY resolution, with auto-leveling and system check at startup. It includes smart sensors to alert for leveling failure, resin shortage, and residue detection. Using MSLA technology with a 405 nm COB light source, it also offers a 3.5” touch screen and supports various resins, including washable, ABS-like, and plant-based types.	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 Elegoo Mars 5 and the Longer LK4 3D printers, several key factors highlight their strengths and weaknesses, allowing potential buyers to make a more informed decision. The Elegoo Mars 5, released in 2024, excels in performance, featuring a higher maximum resolution and advanced technology for resin printing. Its compact size, lightweight design, and modern touchscreen display make it user-friendly and efficient for fine-detail prints. However, it comes with a smaller print volume, which may limit users looking for larger models. On the other hand, the Longer LK4, launched in 2019, is designed for filament printing and offers a broader print volume, making it suitable for larger projects. It has versatile material compatibility and includes features such as power loss recovery and a filament end sensor, adding convenience for long print jobs. Its build quality and ease of assembly further enhance its appeal, especially for users new to 3D printing. Both printers are priced similarly, but they cater to different user needs—the Mars 5 being ideal for those focused on detail and quality in resin printing, while the LK4 serves as a reliable, versatile choice for users looking to experiment with various filament materials. Ultimately, the choice between the two depends on your specific printing requirements: if highest resolution and detail are your goals, the Mars 5 is the preferred option; if you want versatility and the ability to print larger objects, the LK4 stands out.
