  • Don’t know about the glue thing, the smds were put by a machine, but they would move like the one in the picture if you didn’t set the machine right. I can’t say for sure with that resolution but I think those white things are the shiny reflections on the pins/solder. I will look into these smd glues tho, that could come handy.

    And about the tape I have to say that my experience with wave soldering is not very vast, literally just one place, but they used painters tape, of the cheapest kind, and it worked just fine—no melting (it’s paper?), and no burning since the solder doesn’t get that hot (~200°C), the tape might stay a bit wet from the flux also idk.






  • It is not a matter of more or less aggressive, some materials dissolve more easily in one type of solvent than in others. You can try, dissolving a teaspoon of salt in water is much easier than in oil. Have you ever eaten chocolate or drunk water while chewing bubblegum? Here the opposite happens, the fats in the chocolate dissolve the bubblegum rubber and make it softer while water doesn’t, it just chills it which makes it firmer.

    Now plastic, rubber, or paints, finishings… can be many different things. IPA is safe to use on natural rubber while oils will make it swell and degrade, or even melt it. But most rubbers are synthetic, basically rubbery plastic. These plastics and other engineered materials can have all kind of different properties, while looking exactly the same. So the only thing you can do, other than research on that particular material and solvent, is trying it on a safer or hidden part of the thing.

    In my experience: oil isn’t good on most rubbers, IPA is ok. For metals (iron, steel, mechanical parts…), contrary to you I usually advise to clean them with oil/grease, alcohol is appropriate if you don’t want it to be oily, only in rust resistant metals. Consumer/industrial products paints and finishings are usually fine with both ipa and oil if applied swiftly and dried quickly– acetone, kerosene, toluene… will strip them away probably. For wood, almost everything will fuck it up.



  • 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.
