    Space Verdict

    The Sunlu T3 is a very capable 3D printer worthy of a spot on anybody's workbench. The combination of fair price, plentiful features, and included spare parts makes the Terminator 3 a very competitive printer in the lower budget segment of the 3D printer market.

    Sunlu is on a roll – after having released its S9 plus printer earlier this year, we can now welcome the Sunlu Terminator 3, or Sunlu T3, to its FDM 3D printer line-up.

    The new Sunlu Terminator 3 has everything you need to get started printing right away, including filament runout detection, clog detection, and power loss recovery. This one is designed to print at speeds of up to 250 mm/s, which is quite impressive, but will the quality be up to par? 

    Let's take a look at the Sunlu Terminator 3 to see what it can do and how its print quality compares to the rest of our best 3D printers.

    The Sunlu Terminator 3 set-up is one of the most straightforward printers we've ever tried. Thanks to the detailed assembly instructions and numbered bags we managed to put everything together in about 10 minutes. The assembly process starts with mounting the upright assembly to the printer base, then you attach the filament spool holder, and finally you mount the power supply vertically on the back of the right side of the Z upright profile. When finished, ensure that the power supply voltage is set to the voltage used in your country.

    Once the printer has been assembled, the next important step is to go through the levelling routine. You can do this by going into the motion menu and then levelling from the main menu.

    The first step is to set the Z-offset. By selecting Z-offset, you can direct the printer to the center of the bed. We set the offset on a piece of regular copy paper so that the nozzle just begins to grab the paper. When you're finished, make sure Auxiliary leveling is enabled.

    You can start your first print now, but there is also a manual levelling option to help make the leveling process more accurate. You will need to adjust the dials on each corner using the paper, just as you did with the Z-offset. The second dial helps to lock each corner into place once you've set each corner. Now you're ready to load your spool and print whatever your heart desires.
