I’ve waited purposefully to review this printer by Longer (lk5 pro). After nearly 300 build hours on it and tons of learning curves I can say it definitely has no issues printing. I’ve printed PLA, PETG, ABS and even the notorious TPU filaments through this and though there is some trial and error involved I can say it’s solid. Its stable heat range seems to max at about 250c with the bed able to stay stable at 90c after that it has problems and fails. I am unsure if putting an all metal extruder on with allow it to get hotter for those exotic filaments but as of now I have no need to check that. The build plate is pretty large too at 300D300W400H allowing those bigger and taller prints to fit. It comes pretty much together with just a little bit of build work involved by fairly simple, the hot bed plate is also fairly nice and seems to do a good job although I’d recommend the first print you do, be a scraper as the metal scraper provided can easily dig and gouge the plate if you’re not careful. It does seem to leave a bit of ghosting residue but most of the time a good wipe with 91% propylene alcohol does the trick. (Pro tip keep you bed warm when you do this) Now for the cons, the bed leveling is rough which is normal on most printers. Manually turning the nobs is barbaric in my opinion and with a machine that is a make it or break situation, literally. Prints turn bad if you’re off .2mm sometimes depending on the detail even .1 makes a huge difference and to rely on a piece of paper and my own judgement is crazy in this day and age. Luckily you can buy a autolevel sensor called a BLTouch. However be warned the information on this is very difficult to navigate. You will need firmware from longer which you request via emailing them. Then you will need pronterface software to both enable and calibrate the leveler to your machine. That’s after you become an electrician and wire the sensor into your main board which can brick the printer if you are careful and ground the sensor incorrectly. And there is a dozen main board designs so you have to be careful not to read the wrong schematic as well. I will say the customer service is top of the line though, and helped me through all of my troubles so don’t turn away or get frustrated if something doesn’t go how you wanted it too. They will help you along the way and are very friendly in doing so. In closing it’s a great beginner printer at a good cost point and is highly upgradable as well, for the price you’re getting such a good. Buy an enclosure for it!!! I cannot stress it enough these plastics thrive in them and it makes such a better quality print. Hope all this helps and have fun!

software is intuitive and works well even if you’ve never used a slicer before. There's a small learning curve, but nothing overwhelming. Pros: Fast, painless setup Good print quality for the price Quiet operation Beginner-friendly software Cons: Build volume is a bit limited If you're new to 3D printing and want something reliable, compact, and not intimidating, this is a fantastic pick. Highly recommended for hobbyists and beginners.

So far I have tried to print 15 things. All I have gotten is misprinted things I have gone thru 2 full spools of filament for what is pictured I have yet to get what I want printed I will be seriously consider returning this POS for something better like a lawnmower at least it will do what its intended to do, I have heard great reviews of the lONGER BRAND, so far you cant prove it to me, here is a list of crap that has gone wrong, I had to return the first one for missing parts, the second one came complete but everytime I tried printing the filament wouldn't stick to the bed unless it was a ginormous print, then it would print half the job and quit saying no filament even though its a new spool, then it would not print fully. It would just quit, why , just why do I always get the JUNk. are there any AMERICAN MADE 3D PRINTERS THIS SIZE???

The media could not be loaded. I recently purchased the Longer LK5 Pro 3D Printer, and wow this machine has completely transformed my 3D printing experience! From unboxing to my first flawless print, every step felt intuitive, efficient, and downright exciting. Here’s why I’m blown away: Build Volume & Precision: The massive 300x300x350mm build plate is a dream come true. I’ve printed everything from intricate cosplay props to functional household items without worrying about size limitations. The dual Z-axis and upgraded extruder ensure consistent layer quality, even on tall prints. My detailed miniatures came out crisp, with zero layer shifts or wobbles. Ease of Use: Assembly was a breeze! The pre-assembled design meant I was up and running in under 30 minutes. The auto-leveling feature (bless this!) saved me hours of frustration—no more manual bed adjustments. The color touchscreen is super responsive, and the UI is beginner-friendly. Even my first-time-printing friend could navigate it without help. Print Quality: The prints are *stunning*. Using PLA and PETG, I achieved smooth surfaces and sharp details right out of the box. The heated bed adhesion was perfect—no warping or lifting, even on marathon 20-hour prints. The resume-after-power-failure feature also saved me during a sudden outage. **Sturdy & Quiet:** The all-metal frame feels industrial-grade, yet the printer runs quieter than my microwave! I could work in the same room without distraction. The filament runout sensor is a small but genius addition—no more ruined prints mid-job. **Customer Support & Value:** Longer’s customer team was quick to answer my (admittedly nitpicky) questions. For a printer in this price range, the LK5 Pro punches way above its weight. Comparable models cost hundreds more for similar specs.
