Longer LK5 Pro 3D Printer Review Exploring Large Build Size and Silent Performance

Description

Highlights of the Longer LK5 Pro 3D Printer

Using the Longer LK5 Pro 3D Printer has been quite an experience. The large build size of 11.8″ x 11.8″ x 15.7″ immediately caught my eye, especially for someone like me who enjoys working on sizable projects. The printer arrives 90% pre-assembled, which means most of the tedious setup was already done before I even unpacked it. Its stable triangular structure, reinforced by the inclined rods, really reduces vibration during printing. This design detail resulted in noticeably smoother and more precise prints, which made me appreciate the engineering behind it. The metal frame adds to the overall sturdiness, giving a solid feel that’s reassuring during long print jobs.

Benefits of the Resume Printing Function and Dual Blower Kit

One feature that saved me more than once is the resume printing function. The printer picks up right where it left off after a power outage or filament run-out, which is a lifesaver for long prints. I remember losing a print halfway through a project before discovering this feature with another machine, so this was a welcome addition. The filament sensor is smart enough to pause and alert me when the supplies run out, reducing wasted material and frustration.

The upgraded dual blower kit is another highlight. It rapidly cools the extruded filament, which improves the quality and detail of the prints. I noticed sharper edges and much better layer adhesion compared to other printers I’ve tried. This cooling system also helps prevent warping on larger models, which is a big plus for me.

Quiet Operation and Print Bed Quality

I was pleasantly surprised by how quiet the printer is during operation. Thanks to the TMC2208 chip drivers on all three axes, the noise level is very low compared to other FDM printers I’ve tested. This makes it easier to run prints overnight or in shared spaces without disturbing others.

The silicon carbide glass platform deserves special mention. Its microporous surface provides excellent adhesion during printing, and yet the models release cleanly without forcing or damaging the print. I found this to be much better than the usual glass or magnetic plates I’ve dealt with before. The platform’s heat resistance also supports a wider range of filament types without warping issues.

Pros of the Longer LK5 Pro 3D Printer

• Large build volume ideal for bigger projects and prototypes
• Sturdy metal frame with a stable triangular structure reducing print vibrations
• Resume printing feature that prevents wasted prints after power cuts or filament shortages
• Quiet performance thanks to advanced stepper drivers
• Dual blower cooling system for enhanced print quality and quick filament solidification

Downsides to Keep in Mind

Despite its many strengths, I did encounter a few drawbacks. The printer is not fully assembled, so beginners might find the remaining 10% setup somewhat challenging without detailed guidance. Although the manual is decent, some additional online tutorials were necessary to get everything running smoothly.

The BL Touch auto-leveling sensor is not included, which means you’ll have to purchase it separately if you want automatic bed leveling. Manual leveling is doable but requires patience and a bit of trial and error for precise results.

Occasionally, the Teflon feed tube, while heat-resistant, can get clogged if the filament quality is poor or if the printer is pushed to very high temperatures. This means some maintenance is inevitable, though this is common across many FDM printers.

Alternative Products Worth Considering

Comparing this printer to popular competitors like the Creality Ender 5 Plus or the Artillery Sidewinder X1 reveals some interesting trade-offs. The LK5 Pro outperforms many in build volume and stability, especially given its metal frame and reinforced design. The noise reduction with the TMC2208 drivers is another area where it shines, as some rivals are noticeably louder.

However, some competitors come with fully assembled setups or include auto-leveling sensors in the box, offering a more beginner-friendly experience out of the gate. The Ender 5 Plus, for example, has a slightly smaller build volume but is known for its extensive community support and easier upgrades. The Sidewinder X1 boasts a direct drive extruder, which can be better for flexible filaments, something this model doesn’t offer natively.

If you’re looking for quiet operation and a large build size at a competitive price, this printer stands out. But if plug-and-play convenience or included auto-leveling is crucial, some rivals might be more appealing.

Value Assessment: Is It Worth the Investment?

Evaluating the price to quality ratio, the Longer LK5 Pro offers impressive features for its cost. The combination of a large build volume, metal frame, and resume printing function gives a lot of bang for the buck. In my experience, the print quality is comparable to more expensive machines, which is a big plus for hobbyists and educators looking for reliability without breaking the bank.

Considering the upgrade potential with open-source firmware and the ability to add auto-leveling, this printer is quite versatile. It suits those who enjoy tinkering and customizing their machines. For users who want a solid workhorse that can handle a variety of printing tasks, this model represents affordable quality and smart spending.

User Experience and Practical Use

My kids got involved with this printer too, and they were impressed by how quickly the prints cooled and how detailed their figurines came out. The dual blower system worked wonders for their small characters, reducing the usual stringing issues we’ve seen on older printers. Meanwhile, my coworker appreciated the quiet operation during late-night print runs, which didn’t disturb anyone working late in the office.

I experimented with different filaments, including PLA and PETG, and the Teflon tube managed the heat well, though I made sure to stick to quality materials to avoid clogging. Swapping filaments was straightforward thanks to the filament sensor, which paused the print and notified me when running low. This feature feels like a thoughtful addition for anyone juggling complex prints.

Summary of Positive Features

• Large, stable build volume with reinforced frame
• Resume printing and filament run-out sensor that reduce print failures
• Quiet printing thanks to advanced motor drivers
• Enhanced print cooling via dual blower fans improve surface finish
• Durable silicon carbide glass bed for excellent adhesion and easy model removal

Areas for Improvement

• Requires some assembly and setup effort, which could challenge beginners
• Auto-leveling sensor not included, must be bought separately
• Occasional feed tube clogging with lower quality filament
• No direct drive extruder, making flexible filament printing less ideal

Testing this large-format FDM 3D printer has been a rewarding dive into its capabilities and quirks. It’s not perfect, but the thoughtful features and solid build quality make it a worthy contender for enthusiasts and semi-professionals alike.
