FLSUN S1 Pro – Fast 3D Printer for Technical Filaments Too?

The FLSUN S1 Pro promises high-speed 3D printing with an enclosed chamber, active heating, and a powerful extruder. But does it actually handle technical materials like ABS, PC-ABS, and PPS-CF10? I tested it with both stock gcodes and my own, including some demanding filaments, to see if it lives up to the hype.

In this video, I go through the setup process, print quality tests, noise levels, and most importantly—whether this fast delta printer is ready for carbon fiber filaments or just another speed-focused machine that struggles when things get serious.
