I've been using this printer for about 2 weeks, and while I haven't had a chance to test the laser engraver and dual extruder's capabilities, so far I'm happy with it. Just to give a brief overview of my experience with a 3d printer, this is my 5th time.
First, the printer comes in a package that is mostly assembled except for the printer's z-axis and individual extruder components. Instructions for setting up the printer as a single extruder setup are included, but I don't really need them as it's pretty intuitive to put them together. Having said that, it seems that setting up the printer for dual extruder use or as a laser engraver requires more setup and instructions for successful assembly. If you plan to use it as a single extruder, you should be up and running in about 15 minutes. It comes with some sample filaments, but I wouldn't rely on them because my printer packs stuff that doesn't print well, and when I try to use them, all my prints fail. However, as soon as I put in a new roll of filament, nearly every sample I ran printed successfully, and those that failed were mostly due to getting used to the printer and determining the correct settings for each print. Once I got used to the machine, my printer printed just fine. Regarding the print itself, I've included some pictures of the samples I printed to show the quality of the print itself. For me, print quality is the most important aspect of any 3D printer and so far I am very happy with it. As far as I can see, the projects I print are fantastic, and if there are any skipped steps, and with no visible ghosting in each printed layer (at least in my eyes), I print them out really well. One of the samples that came with this printer is a 20mm cube that can be used to test the printer's accuracy, and based on the samples I printed, this printer is excellent in terms of accuracy. The X- and Y-axes are 20.02 and 20.04mm, respectively, while the Z-axis is 19.78mm, which is about what you'd expect from an FDM printer in this price range. Once I have time to test this further, I will update my review to include them as well. All in all, it's easy to put together into a monofilament extruder with lots of nice features and good print quality, so even if I don't have a chance to use a dual extruder or laser engraver, I'd consider buying it again.
One last thing, I bought another printer from this company in the past and when I needed to get in touch with them for some information, they were very responsive and helped me with another problem I had with my printer at the time. They got me up and running within 24 hours of my first contact with them, which is rare when it comes to customer service these days, especially after a purchase.

Review of TRONXY 3 SEUnboxing of the TronXY 3 SEI ordered it and it showed up three days later. There was slight damage on the outside of the box. Lots of foam on the inside. Everything is very nicely packed. In the box; Sample roll of white PLA 1.75-millimeter filament. Micro SD card with all of the manuals and software on Micro SD card to USB converter2 very nice spool holders made of aluminum, very sturdy, very functional A scraper with a nice edge on it glass bedA USB cable to print directly from the computer A bag of tools, Its got a full size screwdrivers, miscellaneous hardware, zip ties, the clips for the bed, extra limit switch it and extra hot end partsThe manual is very detailed put together very nicely you open it up and you got the install video QR code, the after sale contact QR code and the Facebook QR code The Z access is completely assembled. It has a 20 by 40 side rails and a 20 by 20 top rail and 20x20 rail for the Y access to run across. Has a 2 6 millimeter leadscrew for the Z axis. Base is made of 20 by 20 side rails for the bed to run on mounted on a base with all the electronics in it. All in all it's very well packed, lots of foam around it. The base is completely assembled the power supply and motherboard are mounted underneath the build plate. The base has nice rubber feet keep from vibration. It has a single ribbon cord for connection between the gantry and base for easy cable management has very nice on off switch, power plug in the back and that completes the unboxing of the unit overall I'm very impressed with the way this was shipped. The bag of tools came with everything you need to put this together.Specs: Print volume on this machine is 255mm by 255mm by 260mm, So it has a very good print volume, The print accuracy is .1 to .3 millimeters. The nozzle size is .4 millimeters. The print speed is 20- 150 millimeters per second advised is 60 millimeters per second.

This is my second TRONXY 3d printer and I am a huge supporter of their quality and user experience. I had no experience or knowledge of 3d printing before my first printer, they provide a detailed instruction booklet and the necessary software to get printing with minimal hassle. These come at a much lower price than typical 3d printers, and they are compatible with popular software. Here is a more organized overview: Unboxing / assembly: - Comes with fully assembled printer base, vertical section, carrying handle, filament holder, glass bed, all the necessary tools- Mechanical assembly consists of screwing in 12 screws in total. This is all very intuitive but it is also included in the instructions (~10 mins)- Electrical assembly involves plugging in three wire terminals, setting the switch to 110V if in US, and powering on. It is impressive how simple they make it. Software: - This is the most challenging step as in order to make your own 3d prints, you must use a 3d modeling software. I use fusion 360, free for hobyists. You then must convert your model into an stl and use a slicing software to produce the gcode. The gcode is what the printer uses to actually create your part.- The provided micro sd card includes the necessary slicing software, as well as example gcode. This allows you to print examples without ever even using your computer first Printing: - This printer is near silent! The loudest part is the fan that is running, no annoying beeps of motors. Everything is self contained in the printer base. This thing runs and prints so smooth! - Lattice glass bed allows the printer to heat up even faster. My previous printer would take about 7 minutes to heat up to printing temperature. This cuts that time in half! Parts also come off like butter! Very smooth surface finish.- For a cost effective printer, this is still able to make internal and external threads, and meet sub millimeter tolerances.

I purchased it for the dual color and laser engraving options and it has met my expectations.Opening the box, I found that the unit was well packaged. The 2 in 1 out hotend was already installed and included was a single filament extruder. Assembly took about 20 minutes. The gantry is sturdy and the addition of a carry handle is nice. The extruder for the second filament is straightforward. Connecting the wiring is easy. There are only three connections to make the flat ribbon cable, the second extruder motor, and the second runout sensor. Included with the printer are Tronxy's glass bed and clips to attach it to the heated plate. The unit also comes with Tronxy's proximity sensor that not only senses metal but works very well with the glass bed.The included SD card contains Tronxy's slicer, Cura, several PDFs with instructions for setting up the two-color printing and test prints. I have been using Cura for several years now, but for the two-color printing I tried out Tronxy's slicer. To me, the directions for setting up the dual-color were straightforward. There was a card attached to the extruder that had additional settings for retraction. The first test print came out perfect. I have printed several other things and have had outstanding results.Overall, I am completely satisfied with the Tronxy XY-3 SE. I would highly recommend this printer to anyone. There is a slight learning curve with two-color printing, but I don't think that beginners would find it too hard to figure out. I have not tried out the laser engraving but I will update this review when I do.Definitely 5 stars for this printer.
