| 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 GTMax3D ProCore A2v2 is a compact and robust 3D printer with a printing area of ??220 x 220 x 240 mm. It offers high print quality, ranging from 0.05 mm to 0.32 mm. Its features include automatic filament detection and changing, travel speed of up to 300 mm/s, and a heated aluminum bed with a glass top. It has automatic bed leveling with 16 points and an all-metal hotend that reaches up to 298°C. The printer has a carbon steel frame with electrostatic painting, is automatic bivolt and has connectivity via USB and SD card. The Bowden system and core xy kinematics complete its advanced features. |

Conclusion |
| In summary, both the Longer 3D LK4 and the GTMax Core A2V2 are respectable contenders in the 3D printing market, each catering to different user needs and budget considerations. The Longer LK4 stands out for its affordability and versatility, allowing users to print with a range of filaments, and is highlighted by its solid build and ease of assembly. With a generous print volume and a maximum nozzle temperature of 250°C, it accommodates beginners and hobbyists looking for a reliable machine without breaking the bank. Additionally, its power loss recovery and filament end sensor add to its usability, making it an attractive option for those just starting out in 3D printing. Conversely, the GTMax Core A2V2 offers more advanced features, such as automatic bed leveling and a higher maximum nozzle temperature of 295°C, making it suitable for more demanding applications and materials. The enclosed design enhances heat retention, which can improve print quality and stability, especially for temperature-sensitive filaments. While it comes at a higher price point, users seeking precision and more advanced capabilities may find the investment worthwhile. Ultimately, the choice between the two printers will largely depend on the user’s experience level, intended applications, and budget constraints. For those prioritizing cost-effectiveness and general use, the Longer LK4 presents an excellent option. However, for users who require more specialized functionalities and are ready to invest more, the GTMax Core A2V2 could be the preferable choice. |
