Unboxing and Box Contents

The Longer LK1 3D Printer is shipped in a sturdy and neat box with foam padding inside to protect it from damage. The manufacturer includes some instructions on the box on how to unpack this unit, and they are quite helpful, to be honest. There are also several essential accessories in there that you will need for both printer set up and operation.

First, you will find a control box and connectors, specially designed for setting up the heat bed and hot end. Each of these accessories is inside its own smaller box, so you will need to unpack them too. The box also includes a single frame base and another vertical frame that should be assembled before you begin printing.

The manufacturer has also included a toolbox in there and reinforcement brackets as well that will be useful in assembling the frame. Other items in the box include a scrapper, a power cord, a USB cable, flush cutters, tweezers, Allen Keys, and both a USB and SD card reader. And just to make sure you can start printing right away, the box also comes with a spool of PLA filament and a spool holder.


The Longer LK1 is shipped already semi-assembled in the factory. This means that even though most parts of this printer are already put together, you still need to do some setup and assembly before you get started. The first step is setting up the outer metal frame. You will find all reinforcement brackets needed for this inside the box.

The LK1 also has an assisted bed leveling feature, something that makes it easier and faster to set up this unit. The function can be accessed from the LCD touchscreen on the printer. However, you will also need to attach the control box onto the unit. According to the manufacturer, this entire set up and assembly process should not take more than ten minutes. Besides, there is a detailed manual on the manufacturer’s website that you can download and use for the first time set up.


The Longer LK1 is compatible with three leading slicer software solutions, including Cura, ChiTuBox, and Repetier – Host. These are all third party slicers and can be downloaded directly from provider websites. Cura has a reputation for ease of use with most users, but you shouldn’t run into any problems if you decide to go for Repetier Host or ChiTuBox. The Longer LK1 is also compatible with several operating systems, including macOS, Linux, and Windows 7 and above.

In Use

The Longer LK1 delivers some outstanding print quality for several reasons. First, the unit is fitted with a high precision nozzle Hotend. Secondly, the printer features an advanced movement system and a sturdy metal frame that enhances overall print stability. All these factors are essential for improving the print quality offered by this model.

The Longer LK1 is also fitted with a quiet motor. It also features a V-slot design with POM wheels, all perfectly suited to offer a noiseless printing experience.  We also noted that the Longer LK1 provides effective heat dissipation and cooling, thanks to its innovative Thermal cooling system. The system delivers faster object solidification, too, making it relatively easier to remove printed objects once they are completed.

Customer Support

The manufacturer of the Longer LK1 offers up to four support options for clients. In case you are having issues with your printer, you can reach out to the support team through email, phone call, WeChat, and fax. The company claims that it responds to customer queries as fast as possible.

We were not able to find any reviews online that back or disapprove these claims. The manufacturer also offers several support materials through its website, including videos and detailed manuals on how to use and set up the printer.


The Longer LK1 is an extremely versatile printer that offers a large build volume, high-quality, precise printing, and smooth, noiseless operation. This makes the unit a perfect choice for various applications, including architecture, education, art, and Jewellery, or even some general hobbyist creations.

The LK1 also comes already semi-assembled from the factory, allowing you to set it up in less than 10 minutes. We also loved the interactive LCD touch screen display, sturdy aluminum metal frame, assisted bed leveling, and dedicated cooling and heat dissipation technology. 

Despite these notable features, the Longer LK1 also has a few shortcomings to be aware off. The printer is quite large, so you may need to find enough space for it on your table or countertop.

Although the unit is semi-assembled, it still requires some assembly, something that can be very technically challenging for some people. But despite these minor downsides, the Longer LK1   is a top quality printer that should be worth the money, primarily because of its print quality and outstanding durable construction.

  1. Dylan, thanks for taking the time to review the Longer LK1 3D printer. After looking into several 3D printers over the last couple months, I finally decided to buy this one on Amazon last night. It should arrive by Sun. evening. I’m excited to start learning about it and printing. As per your review, I’ll start looking into Repetier Host or ChiTuBox slicing programs to see which one will work best. Have a great week.
