    • Great 3D printer for beginners.

The media could not be loaded. 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. ... show more

    • Save a Ton of Money with a Little Work and Know-How
Size: LK5 Pro
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. ... show more

First off, I'm a total noob at 3d printing ZERO experience. So far my experience has been very positive thanks to this printer. I opted for the LK5 Pro because of it's large format capability and it's cheap price. I also wasn't afraid to put in some work &$$$ upgrading parts if it was a POS. Thankfully It's not. Out of the box I was printing within 2 hours. I took my time setting things up and getting everything adjusted. Printing PLA on glass side w/no adhesion helpers & everything sticks really well. First thing I printed with 100% stock settings was a Benchy. It printed no problem. Next up were a few temperature towers to get temps dialed in. After that I printed two test beds with minor adjustments between prints. Pictured is the second test bed. Looks pretty good IMHO. I like the Longer LK5 Pro. Their FB group is full of helpful people. I haven't had any issues so no customer service reviews.... For the money I don't think you can do much better. I've had it for all of 4 days so I'll update if any issues arise. ... show more

This is my third Longer 3D printer, and my 2nd LK5 Pro. This printer is far superior to similar, higher-priced models on the market. The LK5 Pro has improved on everything that came before. With a large build volume, 300x300x400mm, you can print some very large items. My largest so far was Wyze Phil, standing at 250mm tall. Built-in Features include Bed Leveling Assist, Filament Load/Unload Assist (both built-into software) Color Touch-screen display, lattice glass coated bed (prints just slide off once cooled) and a filament sensor. Well designed, the rails do not contain any top-facing opening or gaps. All smooth surfaces. And it just PRINTS! Super easy to setup and get started. I was printing within an hour of opening the box. Great Quality Prints, Great Price, Great Printer! ... show more
