Review on 🖨️ High-Precision UNIZ Monochrome UV Curing Printer at 3840X2400 Resolution by Adolfo Goins

I have over a year of resin 3D printing experience with QIDI Shadow 5.5s. And I've printed many of the parts I've designed using Fusion 360. In this test I compare my experiences with the UNIZ Ibee and my Qidi.Fan. The fan makes a lot of noise and UNIZ is much louder than my QIDI. When a print is complete, Qidi will emit a beep to notify completion, while Uniz does not. I'm missing it. The printed instructions that came in the box are of the lowest quality and unreadable. Fortunately, you can find the same document in PDF format on the memory card. It's quite limited and it was useless for me to get my wifi to work. I could not connect the printer to my wireless router and there was no further help. (I have yet to contact support for now) The printer has the same thin (about 3mm plastic) hood as the Qidi and feels cheap. Before I started using the printer I built a lift for it to keep it clean and for my own convenience. There are four screws on the bottom for leveling the machine, but the stand is too short for practical use. At best you can adjust 2-3mm before they fall out. The image of the part to be printed is projected onto the Qidi display. It is convenient to select a file quickly and without errors. I love it and miss this feature on Ibee. There you will only find the file name. During the printing process, Qidi projects the current layer onto the display and I use it to test the print. I miss that on ebay too. There you will find a "timer" that shows how much time is left in the print. The tools (on display) allow you to manually raise the tabletop, but not lower it. The symbol suggests this and is therefore incorrect. A small thing for me. There is a lot of feedback on the program (uniz maker) and I can only agree that it needs improvement. I use a 3D mouse to connect and the Chitubox software supports it. But Uniz's manufacturer software doesn't do this and it's missing. So I just use the Uniz Maker software to slice the model. I use Chitubox to prepare the model beforehand. A nice feature of Uniz Maker is that you can align the face to the build plate and it has an auto position feature which I like. I used the zMud 3D resin that came with the kit. I didn't get the results I was hoping for, but it's also a learning curve with a new printer and an unfamiliar resin. The first prints had misprints which I never had. (like Sirayatech Fast) I don't want to jump to conclusions just yet as this is a new printer for me with a new resin. I've encountered strange print anomalies in my prints with every resin I've used. Eventually I replaced the FEP film in the resin tank and only good prints from that point on. I am satisfied with the print quality. Print speed is disappointing so far; just a bit faster than my other printer, but maybe I need to tweak the settings further. The exposure time is short and I hope this will extend the life of the LCD screen. (My other printer has already had the LCD screen replaced twice in a year.) Qidi printer prints show large "elephant paws" on the first number of layers printed. That doesn't happen with Ibee. I think it has to do with the better LED configuration. The build plate is fairly flat and a fair amount of resin doesn't drip. Also, the support that holds the build plate is dipped in resin. A little messy and could have easily been avoided if this part was a bit bigger/longer. The build plate screw is a relief from what my QIDI has. On my QIDI, the paint on the resin container was peeling off and was not resistant to the aggressive resin. I didn't expect this to happen with Ibee. But it is also true that the coating of the metal part that holds the construction plate with 4 screws has come off. I recommend removing this coating before printing as it is not resistant to zMud and/or Siraya tech Fast, the resins I have used with this printer to date. (see image) This is a design flaw that should be corrected by the manufacturer. The coatings on the other parts that come in contact with the resin are holding up well so far. For now I can recommend this printer! Update May 2021: There are fewer and fewer misprints on prints, but they still happen. After many prints my opinion changes in favor of Uniz Ibee and I use this printer mostly.
