Super Racer (SR) So Fast

SR is the latest Delta-based 3D printer independently developed by FLSUN.

Fast printing speed is its biggest advantage. Its default printing speed is 150mm/s (about 3-4 times that of i3 architecture), and even if it runs at 200mm/s, its quality performance is good. Compared with other ordinary 3D printers, printing the same model can save about half of the printing time!

SR uses a 32-bit high-speed motherboard with four TMC 2209 installed on the motherboard. It is quieter, more stable, and has higher printing accuracy.

FLSun Super Racer Key features:

  • 150-200 mm/sec printing speed.
  • Large build volume 260x260x330 mm
  • Fast, Accurate, Powerful & User friendly
  • BMG Extruder clone
    • Dual Drive(Gear) extruder to more reliably extrude filaments and more reliable filament feeding. The unique dual feeding filament gear can minimize slippage and increase the filament feeding force to adapt to high-speed printing
    • Ensures jam-free feeding of flexible filaments
  • Volcano hot end
    • The Volcano Hotend allows you to print thicker and wider tracks, resulting in significantly shorter print times. Such a hotend also allows you to experiment with different nozzle sizes and flow rates and be more creative and exploratory in 3D printing with high melting capacity.
  • Heating Bed with Removable Glass Plate(Lattice)
    • The printer comes with a heating bed with two practical features—it is removable and made of tempered glass. The textured surface provides great adhesion allows you to remove models easily.
  • 32-bit motherboard with TMC 2209 driver
    • 168M high-performance 32-bit processor, higher computing speed, and with TMC2209 silent drive.
  • Linear Guide
    • High-precision linear guide, providing higher printing accuracy and stability and lower noise.Print at higher speeds while maintaining maximum print quality.
  • Removable magnetic auto-leveling sensor
    • Auto bed leveling system,  easy to start printing
  • Filament run-out sensor
  • Print recovery after power failure
  • Carbon fiber Parallel arm
    • The high-precision 3K carbon fiber rod brings a better printing surface, and the zero-gap design makes the movement more precise and the installation easier.
  • Dual air ducts for improved cooling
  • Open source Marlin firmware
    • Based on Marlin 2.0.6. the self-developed open-source firmware supports the resume printing and filament sensor function.
  • 3.5-inch capacitive color touchscreen
    • A 3.5-inch capacitive touchscreen with a redesigned user interface and optimized operating logic with user habits supports 8 display languages. It has a function for resetting the factory settings with just one button.
