Extra features	The Ender 3 V1 is a DIY assembly 3D printer, a sales leader since 2017, standing out for its cost-benefit. With a wide printing capacity, it has a CNC machined structure for precision and stability. It offers high-precision prints with low noise, thanks to its innovative V-profile and pulleys. It has a self-adhesive magnetic platform for easy removal of models and excellent adhesion. The Ender 3 heats up quickly, reaching 100°C in 5 minutes, ideal for agile prints. It includes protection against power failures, allowing you to resume printing after interruptions, saving time and material.	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 BIQU B1 is an advanced 3D printer with a silent 32-bit BTT SKR V1.4 motherboard and ARM Cortex-M3 CPU, offering DIY interfaces (I2C, SPI, WiFi) and dual Z-axis. Its dual BTT B1 TFT35 V3.0 operating system allows real-time monitoring and multiple printing modes, including G-code visualization effects. It stands out for its BIQU SSS (Super Spring Steel), ensuring easy model adhesion and simplified removal, with the possibility of using it on both sides. It includes a filament sensor, automatically pausing printing in case of filament breakage. The multicolored RGB lights integrated into the hotend allow you to view the printing status even at night. Additional notes include the need for a BIQU-specific Type-C cable and extra interfaces for smart filament sensor and BL Touch.
