The orange 4K is a resin printer-with-good-volume-to-start-in-the-hobby/">3D printer produced by longer3D that can boast the fact of reaching 4K resolution thanks to its monochrome LCD screen with stereolithography printing technology, which results in models with quite a wealth of detail on its surface. With that said, the LONGER Orange 4K It offers a build volume of 120 x 68 x 190mm and has extra goodies that we don’t see all the time in this price range, like dual liner guides on the Z-axis.

Its LCD screen makes it possible to reach a resolution of 31.5 microns and even finer in printed models, and that is something really beneficial and rare to see in this price range. If you are interested in knowing this model in greater detail, you have come to the right place.

This is the LONGER Orange 4K

This 3D printer boasts a quality finish with metal body which not only contributes to a premium appearance, but also helps maintain the stability of the frame for wobble-free prints.

The Orange 4k uses the same resin tank as its little sister, the Long Orange 30, another resin printer that we can highly recommend. With that said, the Orange 4K is similar to the latter in terms of design, but has the benefit of having dual Z-axis linear guides that ensure smooth and stable movement, again, this translates into better performance when it comes to speed. to print models.

In another order of ideas, machine ships pre-assembled and requires little from the user to get operational. Once out of the packaging, all you have to do is slide the build platform into the machine, screw it down and level the bed. While the latter is a manual process, it’s not as arduous as it would be on a filament printer, so it’s not a big drawback.

To interact directly with the machine, there is a touch screen on the front of the printer, which has a diagonal of 2.8 inches. In this sense, its interface is functional and intuitive, as well as rich in options, but unfortunately the user experience is affected by the tiny size of the panel.

LCD display and features

Going into technical details, the LONGER Orange 4K has a 405nm UV LED panelwhich shines through a 5.5-inch 4k monochrome LCD display with a resolution of 6480 x 3840 pixels. At this size, each pixel would have a side length of 31.5 microns, while on the Y axis it would be 10.5 microns. It should be noted that there are two versions of this printer, one with a color screen and the other monochrome, but in this analysis we are only taking into account the Mono model, whose precision is greater.

For his part, the build volume is 120 x 68 x 190mm, which is not bad at all for the price. In addition, the bed has a sloped top surface, so excess resin drains quickly, making it easy to clean up after a print is finished. Meanwhile, the rosin tank is located above the LCD screen and is attached to the base with two thumbscrews.

As if that were not enough, it can print 1 layer every 1.5 seconds, which means that it is considerably fast. How much? well at least 2.5 times faster than Orange 30 working with the same parameters.

LONGER Orange 4K - 3D Printing

It is for the reasons stated so far that we can establish that the LONGER Orange 4K is a reliable resin printer capable of producing detailed prints high resolution in a short time and for an extremely competitive price.

Connectivity and software

In terms of connectivity, the machine only has one USB port that we can use to connect it to the computer or print from a USB drive.

Speaking of USB drives, the machine ships with a 8GB pendrive containing all the necessary documentation for the printer, such as video tutorials, cutting software and some models that you can print. In terms of software, the Longer Orange 4k has support for 3 cutting programs: Chitubox, Lychee and Longerware, which is the manufacturer’s own software.

Additionally, the USB drive contains profiles to work with different types of resin and layer heights, which work quite well and save us effort when making calibrations.

Regardless, we have to applaud the broad slicer compatibility and overall ease of use of this machine, making it a great choice for beginners to the hobby, as well as veterans looking for an affordable alternative. .
