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 Elegoo Mars 3 PRO printer stands out for its special features, such as its high printing resolution, which guarantees sharp and detailed prints with 35 microns. It includes a replaceable air purification module, which facilitates maintenance and improves air quality during printing. The device's LCD screen is scratch-resistant, increasing its durability, and a strong point is the uniform distribution of light, guaranteed by a Fresnel lens. This lens ensures more uniform curing of printed objects, contributing to superior print quality. With these features, the Elegoo Mars 3 PRO presents itself as a robust and efficient choice for resin 3D printing.
