Ston-Wolf Printer

[Zepherino]

This printer has been tempting me so much... It has a pretty unique (afaik) motion setup and a fairly competitive price for the parts involved.

Cartesian with a fixed bed. This is pretty interesting since it means much shorter belts vs CoreXY, but you still avoid the mass of a moving bed.
CPAP blower with consideration to noise
Super thick CNCed and carbon fiber parts
Stock Klipper/Mainsail with pre-made profiles

My only gripes so far is lack of enclosure (to be resolved by July based on claims), and the V6 based nozzle setup. V6 nozzles are great since you have a lot of choice, but I hate hot tightening nozzles, and the Revo has really spoiled me.

There's a video of a 7 min benchy in PETG. Pretty good quality for the speed. The blower still seems pretty noisy, but that's probably tough to avoid

That thing is a work of art, no doubt. Comes with a matching price tag though. Not sure I'll be picking one up in a hurry.

Super cool design!
This is my first time seeing a printer with a CPAP setup. Are they all this quite or did this guy just do some amazing design?

Good video

There's a lot of variables, but generally I would say CPAP fans in printer setups tend to be pretty loud since they fan is relatively small and needs very high RPM to maintain static pressure. Maybe a hair dryer in comparable noise. From video footage it seems the whatever muffler/silencer ston-wolf uses does very well, but without AB testing in person, I can't say for sure.
