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.
