    • Perfect first 3D Printer for me
Size: LGT-LK5PRO
Review Image by JSimp JSimp
I have had my Longer LK5 Pro for over two months, and I have over a kilogram of filament and about 200 hours of print time on it. I love it. This is my first 3D printer, but I am impressed with the LK5 Pro’s print quality, the large full color touchscreen, and how easy it was to set up. I consistently make parts with tolerances down to 1/10th of the millimeter. The machine is large! I could not find any dimensions of the unit, outside of the build volume, when I bought mine. It’s outside dimensions are approximately 24” deep x 20” wide x 26.25” high without a spool of filament, so plan accordingly. In sort, I would recommend the LK5 Pro to anyone as a first printer, for someone looking for a larger build volume, or as a general workhorse production printer. The long story: This is not going to replace any six-figure commercial printers, and I know the Longer is an Ender clone. The quality of the machine and its prints are very good. The 300mm X 300mm X 400 mm build volume is worth the extra money. I watched dozens and dozens of review videos, and I had none of the small fit and finish issues the reviewers reported. (They must have had early production printers?) All of my wheels and bearings were tight from the factory, and I have only made small adjustments after many hours of printing. I took my time and spent an hour squaring the final assembly and tramming the print bed with a feeler gauge (not with paper). I used the included filament to print the “Benchy” file included on the micro SD card the same night I opened the box. (Go ahead and order up a spool of filament because the sample is all that comes with the printer, and you will want to make a lot more stuff right away!) I made no adjustments and used the factory settings. The test print quality was impressive compared to most 3D printed things I’ve had experience with. Longer appears to be making improvements and upgrades as their team and users find them. The Maker community is also busy making upgraded parts to print, so I don’t feel like I’m alone with my printer choice. I find 3D Printing to be like any other hobby I’ve had. People are quick to join a “tribe” and declare anything other than what they have to be junk and a wast of time and money. Like any piece of equipment, there is fine tuning and experimentation to get it dialed in. Every filament is a little different and you will need to tune the printer accordingly in your slicer software. (That is part of the fun and how you work toward being and expert in something.) No tech gadget is truly plug and play or set it and forget it. In the end, do your home work and get something you like so you can make something! My personal experience tells me the Longer LK5 Pro was a very good choice and has opened up a whole world of design and production to me. ... show more

    • Longer LK5 Pro is easy to use and set up. I love it!

The media could not be loaded. Purchased the Longer LK5 Pro 3D printer a few days ago and it came fast. It has been a dream to use. I would definitely recommend this as a great printer for anyone starting out with 3D printing or even for veterans that want a more compact and reliable unit for it's large size. I am extremely impressed. SET-UP. The setup was straight forward. It took me about half an hour to have it fully setup and powered on as they advertise it being about 90% already set up. Well it's true. All the tools needed are provided with the unit to complete the full setup. There are a few great youtube videos on setting up that you can watch as well if you need a little extra help. OPERATIONS. Very easy to use. This is not my first 3D printer, so I do have a little bit of experience with them in general. But this was still a very easy printer to simply start using. Leveled the bed, loaded filament and printed the test print. It came out absolutely flawless on this LK5 Pro. I am very impressed. Like I said, I have had it for a few months now and it has been rock solid. I have not had a single issue. Just load filament and print. I've not even had to re-level my bed yet. QUALITY. The unit itself is very sturdy. The hardware used is good quality. Everything aligns very well. I do not foresee any issues with quality in the future. They run multiple test before shipping it out to you Quality is top notch. VALUE. You will not find a better printer for this price. This printer exceeded my expectations on every level and the volume is just a added bonus. ... show more

    • Really enjoying this 3d printer from Longer
Size: LGT-LK5PRO
This is my first 3d filament printer. This item shipped in a form fitting poly-ethylene foam liner inside a sturdy cardboard box. It arrived in perfect condition, no dents, bends or scratches. All parts were easily identified. Set-up was fairly easy, even with the original manual with the dark pictures. There is a new manual available on the Longer website which is much clearer. The Changlish is better than usually included with items like this. There are also a few un-boxing and setup videos on YouTube, so setup should not be an issue. I've enjoyed learning about 3d printing over the last couple of months. My initial benchy print worked very well but as I began tweaking settings and experimenting I began to have bed adhesion issues. I was able to overcome these by tweaking temperatures, bed leveling and initial layer print speed, but I think my real problem was the extrusion speed. Once I calibrated the extruder, the bed adhesion issues went away. It was under extruding at about 92% of what it should have been doing. I've also printed an improved fan shroud which has improved quality or overhangs and bridging. Got stringing under control by adjusting retraction and nozzle temperatures and I'm really happy with the results. I've only used PLA so far, but it's supposed to be capable of nozzle temperatures up to 250 C and bed temperatures up to 100 C so I will branch out in the future. I'm planning on replacing the plastic extruder assembly with a metal one, but I don't expect that to affect quality much, I just want a metal extruder to improve reliability. The frame, diagonal braces and under-slung power supply seem well-built. The bed and nozzle both heat up in a reasonable amount of time. Items really stick to the hot bed, but once it cools they pop right off. I've experimented with the power failure feature, it works but you need to get things going again before the bed cools too much. The unorthodox position of the filament reel does not present a problem for me but could could be modified if desired. My tallest print, so far, has only been 220 mm but there were no issues at that height. With the sturdiness of the frame, and the good bed adhesion I'm getting now, I expect much taller items could be printed with no issues. I am using the printer with an OctoPi interface, but did my initial testing using a micro SD card. Both methods work well, but the additional convenience of the OctoPi/OctoPrint setup is wonderful. I am also using the Prusa slicer which probably complicated the learning curve. I just preferred it's user interface. This printer was not plug-and-play (except with the benchy) so I would not recommend it for someone inexperienced and uninterested in tweaking and adjusting a printer to bring it into line, but I love that kind of stuff, it's just a hobby for me. I would recommend this printer to anyone who anticipates using it's full capacity (300 x 300 x 400) and has experience with 3d printing or wants to learn how to get the most out of a printer. ... show more
