I am a newbie to 3D printing. This was my first venture into the 3D realm and was looking for a good quality printer for a reasonable price. The Longer LK 5 Pro was the best decision I have made! The package was the best of anything I have ever gotten online. Packaged very securely in foam as seen in my first picture. Everything was well thought out by this company. Hardware and tools needed for assembly were supplied, with the screws neatly packaged individually and labeled to match the instructions so you knew exactly what screws to use. It also came with a small bag of "Extra Parts" which I later found out was a filament feeder, a strain relief and 2 small caps which I have yet to figure out where they go. These are not listed on the instruction sheet, but videos are provided on the USB drive. Instructions were intelligent and well written. There was one printing error I found, but I figured it out easily. To keep this short, I'll list my Pros & Cons: Pros: Well packaged. Very good instructions, and there are YouTube videos that you can watch as well on assembly. I had trouble reading some of the instructions, simply because of the small print in some sections (my problem, not theirs). The unit is 90% pre-assembled, the rest is not difficult to assemble when following the instruction sheet. The printer can be operated as a stand alone, meaning you can load the files onto the micro SD card (provided), and load them into the printer. There IS a printer port if you wish to direct connect the printer to a computer, but it is not necessary. The USB/micro SD is loaded with Cura as well as several small projects for you to begin printing. Included in the package, is a small amount of filament for you to print your first item. The control panel is a touch screen panel, which I really like, and it is easy to navigate. My last picture is a short video of how quiet this unit is. The only noise it make is from the cooling fan. Cons: Not many, and they are more of suggestions. 1. Please don't put the reminder sticker OVER the voltage switch. (As seen in my 2nd pic). That switch should be easily accessible. 2. The supplied putty knife should be made of plastic. NOT metal. We are working with a glass bed and it certainly does not need to be scratched. All in all, you cannot go wrong buying this printer. I am presently printing my first item from their supplied file. While it is not yet completed, from what I am seeing, the build is very clean and smooth. I can hardly wait for it to be complete so I can play some more. The only issues I had on assembly, other than the small print, was getting an error 9 message when I attempted to level the bed. I found that one of my connectors was not fully seated. Easy fix. The other was not getting the filament fed into the unit far enough for it to start printing. Both, beginners errors.. I am one HAPPY lady! **UPDATE** Added my first test print.... LOVE this printer!!

This is my first 3D printer and my first foray into the realm of 3D printing. I chose the Longer LK5 Pro over the Ender 3 for the touch screen interface, larger build volume, and price. To me, they are all pretty much the same since they use the same open source design. I'm sure there may be differences in quality of stepper motors or hot ends and extruder, but I am too new to 3D printing to notice the difference. The Longer LK5 Pro is a great machine. Assembly was easy. It would have been easier if I had watched the assembly video provided on the SD card first. The photos on the written instructions are really bad (see photos). During assembly, I removed a white sticker from one of the vertical z- axis tracks. This was placed there to indicate the z-axis limiter switch. Tech support was quick to get back to me with the measurement for switch placement. Print quality is good, could probably be even better once I calibrate the extrution feeder. I used NovaMaker's Silk Green PLA filament for my test prints. The all-in-one printer test showed very good prints. The overhang test began to falter from 50⁰ to 80⁰. The bridging test was good all the way up to 25mm. The textured glass bed is nice. I use Elmer's Washable School Glue Stick to help with adherence to the bed. So far, all my prints have come off cleanly, once the bed has cooled to room temp. The Longer slicer program is rudimentary but very easy to use for beginners. It is a bare bones version of Cura, so it is easy to step up into more print features. Within a week, I have been able to learn enough Fusion 360 and Cura to go from design to prototype. I definitely recommend downloading the temperature tower and all-in-one printer test from Thingiverse. It really helps understand what your printer/filament combination can or can't do.

I've had this printer going 3yrs now and it served me really well. Printed a couple of parts for my RCs and other household items/parts. The speed is nothing to cry about as it is outdated and slow. The size for your print space is around 11in, so it's a decent area. To level this you may need to spend around 5min or so since it's a little hard to level given it's manual leveling. I love how this prints corners sharp compared to my Elegoo where it always comes off rounded. One thing to note also is that the gcode for this will obviously be different from other printers. I find my self adjusting tolerance for spacing when I switch from this to my Elegoo. I would recommend this as a starter printer where you can mess around and learn 3D printing without breaking the bank. It's easy to setup and use. It prints great and accurate if you spend the time calibrating it. And has a good build volume. One thing to note on this is that the build plate or build glass loses the stickiness over time so you will find yourself using glue or having to print rafts, so your prints have something sticky to adhere to.

This is real easy to set up and use right out the box only took me 30 minutes to put together. I did so many prints already never had a fail print. Parts are very easy to swap out if anything happens, all around fun and comes in handy for gifts for the girlfriend

This was great when I first got it but after 2 months or so its basically a lead weight. The filament detector has a pretty terrible fan so much so that the company sell replacements and still won't solve the problem. I'd skip on this one and get one with better reliability.

This system is really great, especially considering the cost. Took about an hour to get running but I use these for work so I do have some prior experience. If you have not done this before, this is a decent starting point. You would get more hands-on with a RepRap kit but that can be intimidating if you don't have an electromechanical background. Even so, the LK5 gives you a more advanced platform and you also won't be running into trouble with things like fuses constantly blowing, extrusion issues or tables never leveling. You could spend thousands on something like a MakerBot and get features that are absolutely useless unless you're running a commercial farm (I can print from my phone! but someone still needs to prep the surface so no one cares...) or you can buy this and use the savings on everything else. The extruder works great, the stock metal hotend works great, the glass mat works great, the mechantronics are accurate, reliable and consistent, and the touchscreen interface is actually a lot better than I expected. Right off the bat you have access to a decent utility suite that will run you through just about everything. The only "problem" I have encountered is refresh related. If you are changing a temp and the system is not at the original temp yet, it will have to reach the old setpoint before it displays the progress on the new setpoint. In other words, it will occasionally look like it is not registering commands depend on how you do things but I have found that it is, and will update when it works through the command stack. I consider it a non-issue and it's really not enough to ding any points. Just pay attention. Lastly, the build volume is crazy for the price. This (and the stock hotend) is the main reason I bought the thing and as soon as I get my larger nozzles I plan on using all of it. Standard material issues apply, of course. Do some research and read about polymers. Build a shroud, use some hairspray/glue, understand when you shouldn't use a fan, etc. Do a little legwork and out-of-the-box you can print some relatively high-temperature materials with little frustration. Very few printers will let you print things like ABS or Nylon with zero understanding or input from the user and these are very expensive. On the other hand, all printers with capable hotends will print these materials successfully so long as the user puts in the effort. Be one of those people. As far as my personal use, I actually bought it for sci-fi pop culture models and paintable miniatures and the LK5 works great. Depending on the size I use a .1 or .2 setting and then finish with conventional methods like sanding or in the case of the miniatures I carefully use acetone fuming. Occasionally I make functional parts for work but only if we're at capacity (and only if they pay me!). Whether you are looking to settle for a less-capable $250 model or you are considering a $750+ I would absolutely recommend giving the LK5 consideration. This is an exceptional platform with few issues.

I bought this as a second printer to experiment with upgrades, and to have a larger build volume than my Prusa Mini. It set up pretty easily, most of the work of assembly is already done. The paper instructions are written in pretty good English. I will suggest getting the BLTouch probe kit straight off, as manual bed leveling is a bit of a chore. There are videos and guides online, however, that help with getting this first step sorted out. The printer comes with an antique version of Cura, I would suggest discarding this, and downloading the latest free version of Cura; there is a profile already available for the LLK5Pro in the newest version as of this writing. In my testing, the slicer that comes with the printer did not do a good job, and simply switching to Cura solved most of my issues. My first print stuck to the glass bed so hard it felt like I was going to slice my hand open trying to pry it loose with the supplied steel putty knife. I'm already spoiled by the flexible steel sheet on the Prusa, so I ordered the Fysetc build setup https://www.amazon.com/gp/product/B0861N8FH5/ref=ppx_yo_dt_b_asin_image_o04_s00?ie=UTF8&psc=1 which went on easily, and works brilliantly. There is a self adhesive magnetic base that goes on your heated bed, and the pei coated steel sheet pulls off so you can just flex it, and your model pops right off. Despite the obvious issues I had, I'm not going to ding any stars. I knew going in that this was going to take a little bit of messing with to get it working how I wanted, and the print quality is really good, now. I like the hotend on it, it is very similar to a dragonfly in appearance. Now I have a printer I'm not afraid to modify as needed, which has a rather large build volume.

The Longer LK5 Pro is the first Large format (300mmX300mmX400mm) FDM printer I've owned and it is Great! At $300 at time of purchase it's almost half the price of equal sized 3D printers. The heated Lattice glass bed adheres prints very well without the need of gluesticks and releases the prints when cooling down. The gantry supports that are included are usually a separates purchase on all other more expensive FDM printers and are a must for Z axis that are this tall. Setup was fairly simple and I highly recommend going the Longer Official Facebook group (The community is great and the company admin's are always on there to help) I won free PLA filament from the Longer Halloween contest for the Oni Mask I printed in the photos from (Yu Ryan-Longer Admin). If you are new to FDM printers I would encourage you to do some YouTube research on setting up a 3D printer, leveling the bed, adjusting the concentric nuts on the rollers of the XY&Z axis and proper maintenance. Also register to Thangs.com to find great files to print. The Longer slicer that is included is a simplified version or Ultimaker CURA and a great place to start and after getting your printer dialed in Downloading the full version of Ultimaker CURA as it has a lot more features like different infill and vase mode; I also find that it prints faster with the full version of CURA using the same settings as the Longer Slicer. Get the Longer LK5 Pro and Happy printing.
