SUNLU T3 is a user-friendly 3D printer with quick assembly function, which can be assembled and debugged within 10 minutes out of the box. This article brings you the assembly and use report of T3.

On the outer packaging, SUNLU continues the consistent outer packaging design, Package size: 540*490*330mm. Packed in a thick carton, it can withstand a certain impact and protect the machine well during transportation.

After opening the package, you can see that SUNLU used a lot of sponge to fill the whole box, and the machine was well protected inside the box without any damage.

Key parts have extra sponge protection.

Take out all the accessories in the box. It comes with a separate power supply, rack, needle nose pliers, shovel, 8GB SD card (with card reader), data cable, a roll of white PLA, and screws and a screwdriver.

It can be seen that this is a machine with a quick installation. Only 5 screws are needed to get him into working condition. Following the installation instructions, I installed the machine in no time.

The power supply has its own voltage adjustment, and the voltage of the machine can be adjusted according to the local voltage.

The hot bed uses a magnetic suction design, which is very convenient to let the model get out of the hot bed, which is the current mainstream solution.

Both the X-axis and the Y-axis are equipped with belt adjusters, which can keep the machine belt tight after long-term use.

The model of the progressive motor is TMC4899

Although the machine has automatic leveling, the automatic leveling is only an algorithmic z-axis compensation. If the z-axis distance is too large, it will not print normally. So we need to do a manual leveling first, and then enter the automatic leveling

You can begin the process by selecting ‘Auxiliary Level.’ The 3D Touch probes 16 distinct spots on the printer bed.Once complete It will return to the levelling menu.

Once done, this calibration is saved, eliminating the need to make frequent adjustments. I generally do level at the start of my printing day or if I have to remove the build plate to clean or remove a print for good measure.

Our built-in Filament tested the built-in files in the SD card.

Printing works well.

Then we try to print at 250MM/speed

I have no way to observe whether the speed reaches 250mm/s, because there is no comparable machine around me.

But it seems that the printing speed is really fast, and the speed of the hot end is much faster than the speed of 60mm/s just now.

The motors for the XY axis twitch like crazy. It can be seen from the picture that the printing effect is basically normal, and there is no problem with the fusion between the layers. There are only minor flaws on the outer wall of the model

Because it's a test, I didn't prepare a big model. The overall printing time of the entire vase is about 1 hour and 45 minutes, and my printing time under the parameter of 60MM/s is 3 hours and 25 minutes.

The advertised speed may not be the real printing speed, I believe everyone can understand.

The printing speed of 250mm/s may refer to the running speed and discharge speed of the machine. But no matter what the speed of the printer is, when the printer is printing the first layer, the speed of retraction and Z-axis lift is the same.

This translates into a 30% time saving in the final model print time, although this ratio will vary with the size of the model. The larger the model, the greater the time savings.

I just used the small model to test if the T3 can reach 250mm/s. Because printing speed does not represent the stability of printing and the quality of printing. Fortunately, the small model I printed did not cause any problems with the stability of this printer, and the print quality was normal except for a small flaw.

So the conclusion I gave is: T3 may be able to achieve the theoretical printing speed of 250MM/s, but long-term high-speed printing stability and quality still need follow-up testing. If we really need the T3 for long-term high-speed printing, I might make modifications to the T3, such as replacing the radiator, linear rails, etc. Firmware may also require further updates. In my opinion, this is a cheap version of Ender 3 V2, so there are many options for modification.

For the current price of $149, I think it is very suitable for beginners.
