design and construction Sunlu Terminator 3

The Sunlu Terminator 3 is built on the traditional FDM style, Featuring a sleek base that houses all the electronics, a magnetic build surface, and a vertically mounted power supply. The Sunlu T3 has a 1:1 extruder with an all-metal dual gear extruder.

For its part, the heated bed is equipped with a magnetic and flexible surfacewhich guarantees an excellent adhesion of the models when it is hot, at the same time that it facilitates its extraction when it cools.

SUNLU Terminator 3 - Design

As expected, it is a machine with modular design It ships knocked down, but fortunately it’s easy to get up and running and has a well documented process.

Then there is the issue of the screen, which is a monochrome panel with a rather archaic user interface text based. It is important to note that the screen is not touch, it is operated with a knob, but in its defense, it has all the options to adjust each setting on the printer.

3D printing and features

The SUNLU Terminator3 is a machine that offers a decent construction volume of 220 x 220 x 250mm coupled with a construction speed of 20 to 250mm/s, as well as the possibility of working with multiple filaments in a reliable way, mainly PLA, carbon fiber, ABS, PETG and TPU.

SUNLU Terminator 3 - 3D printing

With that said, print quality is pretty good, especially when you consider the price. However, we advise against using the advertised 250mm/s fast modesince using it results in a large number of damages for complicated models, specifically in an increase in fibrous, frayed layers and rough surfaces that need to be treated later.

Changing the subject a bit, the SUNLU Terminator 3 offers several features that we normally only see in higher-end 3D printers. First of all, it has 16 point auto leveling to calibrate the heated bed. Second, it’s equipped with not only a filament sensor, but also a dedicated one to alert you to filament clogging. As if that were not enough, it has a function to resume printing in the event of a power outage and a belt adjuster for the X/Y axes.

Connectivity and software

As expected, the machine has a USB-B port for the computer and an SD card slot to print locally. Naturally, it is compatible with the most common cutting programs such as Ultimaker Curebut there are no pre-designed profiles for it, so you have to make manual adjustments.
