Known for its speed, the FLSun V400 3D Printer doesn’t disappoint as a Delta printer. Priced at $849, it’s the ideal 3D printer for makers in a hurry, offering both speed and quality prints. Operating at a default speed of 150 mm/s, it’s three times faster than the average Cartesian-style printer, such as the Ender 3 S1 Pro. For instance, it can produce a perfect Benchy in 40 minutes using default settings, while an Ender 3 would take 1 hour and 53 minutes at its recommended speed of 50 mm/s.
Moreover, its Cura profile can be adjusted to achieve even higher speeds. A 20-minute Benchy was easily printed using thicker layers, fewer walls, and lightning infill. Although FLSun claims the V400 can reach 400 mm/s, the company declined to provide a Cura profile to achieve these results.
To achieve quality prints in less time than traditional printers, the V400 uses Klipper and a high-flow Volcano-style nozzle. Klipper, an alternative firmware to Marlin, is typically an aftermarket mod installed on a Raspberry Pi, but the V400 comes with Klipper straight from the factory.
With its tall and slender design, the V400 has a smaller footprint compared to bed slinger printers, but it requires significant height due to its unusual design. Measuring 45 inches tall (including the spool holder), it boasts a roomy ⌀300 x 410 mm cylindrical build volume, comparable to Anycubic Kobra Plus or Creality CR10.
In terms of specifications, the FLSun V400 has a machine footprint of 482.6 x 406.4 x 1143 mm, a build volume of ⌀300 x 410 mm, and weighs 16 kg. It supports PLA/PETG/TPU/ABS materials, features a direct drive extruder with a .4mm Volcano-style nozzle, and includes a PEI Spring Steel heated build platform. Other features include a filament runout sensor, bed leveling with a detachable probe, and connectivity options such as USB Stick and WiFi. The interface is a 7-inch Speeder Pad with Klipper.
Upon purchase, the FLSun V400 includes all necessary tools and accessories for assembly and maintenance, along with a USB drive containing a user manual, video guides, and Cura 4.13.1 software. Notably, the printer does not come with a replacement nozzle, but replacements are available for purchase on the FLSun site.
Assembling the FLSun V400 is a time-consuming process, taking about an hour due to its massive size. The printer arrives in kit form, and assembling it requires a large table and possibly a stepladder if you’re on the shorter side. A separate leveling switch, magnetically attached to the hotend, simplifies the bed leveling process, which is done automatically by the computer.
Filament loading can be challenging due to the machine’s size, requiring a step stool for access to the top. Filament enters through a hole at the top and is pulled through the center of the printer to the hotend. The 7-inch Speeder Pad, functioning as the control system, runs Mainsail and provides a user-friendly interface for managing prints.
Design-wise, the FLSun V400 is a delta printer with three slender carbon fiber arms, offering a clean look with an open frame. The 7-inch Speeder Pad, serving as the control system, is a standout feature with robust functionality, running Klipper and enabling direct PC control.
Despite some small design issues, such as the spool holder and channel covers, the FLSun V400 impresses with its engineering. The company provides Ultimaker Cura 4.13.1 and one generic profile, facilitating the slicing process. Sliced files are transferred to the V400 via the Moonraker plugin, Mainsail, or the supplied USB drive.
Performance-wise, the FLSun V400 excels in speed, producing high-quality prints at impressive speeds. It handles materials like PLA and PETG with ease, while TPU printing requires some tuning for optimal results. The printer’s heated bed, coupled with the Volcano-style nozzle, contributes to quick and efficient printing.
In conclusion, the FLSun V400 3D Printer stands out as a user-friendly and efficient 3D printer, particularly for those in need of rapid prototyping. While it has some minor design flaws, its overall performance and speed make it a noteworthy option in the 3D printing market.
