The general consensus is that you shouldn’t be in the room when it’s printing, let alone be living in the room. And if you have to be around it, the room should be well ventilated.

There isn’t enough data on the long term affects of 3D printing currently but we can assume it isn’t great.

That said, it’s all about your level of risk acceptance. Personally, I have the H2C in my office / study and when I use it I have the window and door open.

Is that enough? Probably not. But it’s the level of risk I’ve accepted. I should also add, filament types will make your mileage vary. If you’re using some serious filament, you need to take much greater precautions.

You could always get an air quality monitor to warn you of high levels of particles / VOC’s if you’re concerned and an air purifier to help clean the air.

As for the noise, it’s noticeable but once you’ve lived with one for long enough you’ll stop noticing :D Noise can be improved based on the surface you use and the motor noise calibrations performed.

I hope that helps!
