K1 3D printer 600 mm/s, high-speed printing, AI monitoring camera, full metal hotend kit, direct extruder, automatic leveling and stable cubic frame, carbon fiber filaments, monochrome. Carbon fiber filament compatibility: The fastest K1 3D printers are optimized for carbon fiber filaments, providing users the opportunity to benefit from the mechanical strength and dimensional stability inherent in carbon fiber-filled filaments. Full metal hotend for advanced materials: K1 3D printers for home use are equipped with a full metal hotend, allowing them to smoothly handle carbon fiber and other advanced materials. This feature significantly enhances the overall capabilities of the 3D printer, making it perfectly suitable for demanding advanced printing applications. Advanced cooling system: High-speed K1 3D printers are equipped with an advanced cooling system featuring intelligent cooling mechanisms. This system effectively regulates temperature throughout the printing process, ensuring consistent, high-quality prints. The smart cooling is designed to optimize the printing environment and contribute to the overall 3D printer performance. Enhanced stability: The build plate of the fastest K1 3D printers features pre-installed damping pads, enhancing user experience and contributing to the overall stability of the 3D printer. These advanced damping pads are designed to reduce vibrations and ensure smoother printing operations, addressing concerns related to noise and potential disturbances during operation. The printer is new and has been used only once. Reason for sale: lack of time. I have no objection to anyone who wants to know more about it.
