  • That’s an excellent question, and like most excellent questions I think the answer is ‘it depends’ but I would bet for ‘yes’.

    First, ‘noise’ is a part of the signal we don’t want or we don’t care about. In op’s example they talk about ‘two servers’ one quieter and another louder. The sounds of these sources is the part of the signal we care about so the sound of the louder server isn’t noise in any case. As long as the sound of the quieter server rises above the noise floor and the recording device have the dynamic range to record the sum of the sounds you should be able to ‘measure’ it (as in pointing to differences in the readings when you turn it on and off) and maybe cancel the other server to some extent by processing it.

    Now to this point is a yes but ‘it depends’ because while the sound of the louder server isn’t noise it can rise the noise floor depending on the acoustics of the server room. Some server rooms have lots of reverb and echo, specially when they’re not very full, but in my experience most don’t, many put these plastic curtains to contain the AC and they dampen sound reflections pretty effectively. But with bad enough acoustics, a very loud ‘loud server’, and a quite quiet ‘quiet’ one the sound floor could rise over the quieter server sound.

    Disclaimer: this is from the top of my head, I’m tired and not a hundred percent sure this is correct. Don’t take any important decisions based in my autistic rambling.



  • Yep I know. These are the ones the company buys. I’ve tried others when I had to buy a box while out and about but n a hardware store or even a supermarket. Latex gets destroyed very fast, I didn’t notice much of a difference with vinyl… but you are right I have to try if some other material goes better. The thing is I don’t have a clue what the fuck they put in the inks and nobody seems to be able to tell me.


  • I sincerely doubt these newcomers can achieve at their first try what well established manufacturers haven’t through revision after revision of their machines. The price is the first clue, flatbed uv printers this size start at about ten thousand. Also, important information like which printhead they mount, printing speed (m2/h), uv lamp wattage… is missing which is suspicious at best.


  • Not at all like a resin printer. Imagine a hybrid: the top part is an inkjet printer with a printhead that goes side-to-side shooting ink but instead of paper sliding under it there’s a flatbed not unlike the one in a filament 3D printer. The ink is cured by a uv lamp (or more than one, but I suspect this printer has only one and very small and weak since the smaller lamp I work with costs more than this hole printer) usually fixed to the side of the printhead ‘carriage’.


  • No. Just don’t! You nerds, tinkerers, hackers, makers… listen to me: DO NOT BUY THIS.

    I didn’t think I’d have to read the words ‘Consumer UV printer’ ever. It’s just a deranged concept. UV printers are the worst kind of machines there are. Imagine an inkjet printer but a thousand times worse, I’m not joking. I work with these, but professional/industrial ones, in professional printshops, and they are an absolute toothache for my customers (again, professionals that make a living with printers and similar equipment). The customers like me, because I’m the one solving them problems (even if the bill for the solutions is more often than not a few thousands) but I’m sure the salespeople look under their cars every morning.

    This will only be a hole in your pocket, a piece of junk taking up space in your home, and even a hazard to your health or your kids’ or pets’–UV ink is some nasty shit before curing, some of them make my hands itch even trough the nitrile gloves, and you have to handle and dispose of the waste ink properly ie hiring some waste management service.

    It’s true that you can make beautiful things with them, but for a home it’s just not worth it, just take your designs and your media (the things you want to print on) to a print shop and have them printed there.
