Features Of Flsun V400
Amazing Build Volume

The Flsun V400 features an impressive cylindrical build volume with a diameter of 300mm and a height of 410mm at its highest point, making it one of the largest delta-style 3D printers available in its price range. This expansive build space allows you to create tall vases, large architectural models, functional prototypes, and complex multi-part assemblies without size limitations. The delta kinematics design enables the printer to utilize the full height efficiently, perfect for projects that require vertical clearance. Whether you're printing a single large model or multiple smaller objects simultaneously, the V400's generous build volume provides the flexibility you need for ambitious 3D printing projects.
Ultra-Fast Printing Speeds

Experience blazing-fast printing speeds of up to 400mm/s, dramatically reducing print times without compromising quality. The delta kinematics design, with its three-arm parallel structure, enables rapid acceleration and movement in all directions simultaneously. This innovative motion system allows the lightweight print head to move at exceptional speeds while maintaining precision. The V400's optimized firmware and mechanical design work in harmony to deliver consistent, high-quality prints even at maximum velocities. Whether you're producing prototypes on tight deadlines or running a small production batch, the V400's speed advantage translates directly to increased productivity and reduced project turnaround times.
Pre-Installed Klipper Firmware

Klipper firmware comes pre-installed on the V400, providing a first-rate printing experience and ensuring great usability—even over WiFi. Klipper is renowned for its advanced motion planning algorithms that enable higher print speeds with better quality, precise pressure advance control for cleaner corners and edges, and input shaping to eliminate ringing and ghosting artifacts. The firmware also supports remote monitoring and control through a web-based interface, allowing you to manage your prints from any device on your network. With Klipper's powerful features accessible out of the box, you can achieve professional-grade results without complicated firmware configuration or upgrades.
Intuitive Touchscreen Interface

The V400 features a responsive touchscreen interface that makes printer operation straightforward and intuitive. The modern UI provides quick access to all essential functions including print selection, temperature controls, bed leveling, and system settings. Real-time print statistics are displayed clearly, showing progress percentage, elapsed time, estimated time remaining, and current temperatures. The interface is designed for efficiency, with logical menu navigation and clear visual feedback for all operations. Whether you're a beginner just starting with 3D printing or an experienced user managing complex prints, the user-friendly display ensures smooth operation and reduces the learning curve significantly.
Compact Direct Drive Extruder

With the V400, Flsun has achieved something remarkable: the hotend and extruder have been integrated into an extremely compact and lightweight assembly. This innovative design results in one of the lightest direct-drive extruders on the market, perfectly suited for the high-speed delta kinematics. The reduced moving mass allows for faster accelerations and higher maximum speeds while maintaining precision. Direct drive architecture provides superior control over flexible filaments like TPU, eliminates retraction issues common with Bowden systems, and ensures consistent extrusion even during rapid direction changes. This engineering achievement combines the benefits of direct drive extrusion with the speed advantages typically reserved for lighter Bowden setups.
High-Temperature Printing Capability

The V400 supports nozzle temperatures up to 300°C, unlocking the ability to print with engineering-grade and specialty materials that require elevated temperatures. Print strong functional parts with Nylon and PC (Polycarbonate), create heat-resistant components with ABS, or work with specialty filled composites. The all-metal hotend construction ensures reliable performance even during extended high-temperature printing sessions. Combined with the heated bed reaching 110°C, the V400 provides excellent adhesion and layer bonding for materials prone to warping. This temperature range significantly expands your material options beyond basic PLA, enabling true functional prototyping and production of end-use parts.
Premium Dual Linear Rail System

Each of the three arms on the V400 features dual linear rails, providing exceptional rigidity, smooth motion, and long-term reliability. Linear rails offer significant advantages over traditional rod-and-bushing systems: virtually no play or wobble, consistent smooth movement throughout the entire range of motion, minimal friction for effortless acceleration, and extended lifespan with minimal maintenance. This premium motion system contributes directly to print quality by ensuring the print head maintains precise positioning even during rapid movements. The result is crisp details, accurate dimensions, and smooth surface finishes on all your prints. The investment in quality linear rails pays dividends in both print quality and long-term durability.
Advanced Heated Build Platform

The V400's heated build platform reaches temperatures up to 110°C, ensuring excellent first- layer adhesion across a wide range of materials. The heated bed is essential for printing ABS, PETG, Nylon, and other materials that require elevated bed temperatures to prevent warping and corner lifting. The platform heats evenly across its entire diameter, eliminating hot spots and cold zones that could cause adhesion issues. The textured build surface provides excellent grip during printing while allowing easy print removal once cooled. Auto-leveling compensates for any minor bed irregularities, ensuring perfect first layers every time. The combination of precise temperature control, even heat distribution, and auto-leveling creates ideal conditions for successful prints with minimal user intervention.
