The TRUTH About The FLSun S1 Ultra-High Speed 3D Printer

FLSun makes some lofty claims about their new S1. On paper, it’s twice as fast as the Bambu X1C. But are the specs for real or is it all just marketing? In this video I take a deep dive into this next generation ultra-high speed 3D printer, analyzing it in detail and determining how it stacks up to the competition.
