Since 2017 it has made only delta printers, built for speed: the open-frame T1 series, the enclosed S1 and the large V400 Max all run Klipper. They suit people who print tall parts or want fast prints and are willing to tune a delta. - Firmware and custom firmware: 4/5. The S and T series run Klipper, which Tom's Hardware found close to stock on the S1. FLSUN uploaded the Klipper and Moonraker code for the S1, S1 Pro, T1, T1 Pro, T1 Max and T1E to GitHub in August 2025, more than a year after the S1 shipped, as one-time uploads rather than maintained repositories. - Local control and integrations: 5/5. The S1 and T1 series run Klipper with a stock Mainsail interface on the local network, with no account; FLSUN put the printers' Klipper and Moonraker code on GitHub in 2025, and other software can use Moonraker's documented API. FLSUN's app and web platform add remote control and fleet management. - Third-party filament, slicers and parts: 4/5. Any filament works, and OrcaSlicer ships profiles for the S1, T1 and V400 next to FLSUN's own OrcaSlicer-based slicer (published under the AGPL). The S1 takes a standard removable V6-type nozzle, but effectors and hotend kits are FLSUN delta parts. - Repairs and spare parts: 4/5. FLSUN's US shop lists over 100 spare parts for the S, T and V400 series, down to motherboards, effectors, parallel arms, screens, motors and belts. We found no published CAD for the current printers. - Data and privacy: 3/5. Printing over Klipper needs no account. FLSUN's app does, and its privacy policy describes collecting device data, location signals and usage, without saying where the data is stored. - August 2025: FLSUN published the Klipper and Moonraker code for the S1, S1 Pro, T1, T1 Pro, T1 Max and T1E as separate GitHub repositories, uploaded between 8 and 21 August 2025. - May 2024: FLSUN published the source of FlsunSlicer, its OrcaSlicer-based slicer, on GitHub under the AGPL-3.0. - October 2022: FLSUN published the Klipper and Moonraker builds for the V400's Speeder Pad on GitHub under the GPL-3.0. - March 2021: FLSUN launched the Super Racer (SR), the delta that it says first brought it wide attention. - 2017: FLSUN says it dropped over 90% of its product lines to build only delta printers, and that its revenue fell by 80% as a result. ## FLSUN printers for print farms Running a print farm with SimplyPrint: https://simplyprint.io/print-farms The best 3D printers for print farms: https://simplyprint.io/articles/best-3d-printer-for-print-farms ## FLSUN printers for education SimplyPrint for schools and universities: https://simplyprint.io/education The best 3D printers for schools: https://simplyprint.io/articles/best-3d-printers-for-schools ## Frequently asked questions ### Does FLSUN work with SimplyPrint?
