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.

This printer looks and feels like it should only be used in 2015, as many others have pointed out, the machines sometimes detects no filament and will auto stop the print. They include a replacement filament detector but the one provided broke a week into use. Then the Bowden tube got clogged after fixing the filament issue. It’s too much of a hassle for the price.

The Longer LK5 Pro is a fantastic 3D printer for beginners. It offers a large build volume, making it easy to print bigger models, and the included slicing software allows for fine-tuning, which is great for experimenting and learning. The print quality is impressive, and the printing speed is reasonable for most projects. The inner components are designed with care, protecting your prints and ensuring smooth surfaces. I’ve already started printing some small items, and even as a beginner, I’m very satisfied with this machine. Assembly took a bit of time, but the instructions and demonstrations were clear and easy to follow, so it wasn’t difficult. Overall, this printer offers excellent value, is beginner-friendly, and has made my first steps into 3D printing a very positive experience.

This printer sets up fairly easily, just make sure you have the space to do so. The print bed is high in the center, so when adjusting I need to double the space that the instructions call for at the edges so that the printer head doesn’t ground out on the print bed. So far it works fine. I printed clicky bed leveling adjusters for it and it prints fine unless it’s a larger item, which is sadly why I purchased this unit. Anything larger than 200-250mm across has a pretty good chance of lifting away from the print bed, ruining the print. The larger it is the more likely it is to happen. Smaller items print fine.

I have 4 fdm and 3 resin printers and this is my new fav. I am building another 3d Printed R2D2 and will buy 2 more of these. At 300x300x400mm print surface its the perfect size, and an amazing price. Took 20 min to assemble 10 minutes to level with a feeler gauge I bought from Harbor Freight, it printed a test print perfect on my first print. The best part of this printer is most printers when it runs out of filament (when your asleep it seams) most quality ones will resume but you must be their to catch otherwise the bed cools down and the print pops off ruining the print. This printer stayed hot for over 3 hours till I noticed allowed me to change filament, with the model still stuck to the plate. You can see the transition to black filament in picture. Dont bother with adding the auto level Bl touch this was so easy to level with a feeler gague 3 trips around then perfect HUGE prints. I recommend fully!
