Sermoon D1 : Test of the new Creality printer in a cabinet

This post is also available in: Français Deutsch

Creality’s 3D printer catalogue has been enriched with the arrival of a new FDM printer, the Sermoon D1, a box printer with a print volume of 280x260x310mm.

This machine is not yet available for sale, or in very limited stock, but the Creality 3D Official Store website announces that it will be available in their European warehouse by the end of April, at a price of $639 ($542 on special offer, but without stock), which means that the final price in euros will be between 455€ and 540€.

Technical data of the Sermoon D1
– Printing surface: 280x260x310mm
– Heated platen with Ultrabase surface
– Silent 32 bits motherboard
– Colour touch screen
– Double Z axis
– Direct drive extruder, full metal
– Cube structure, with transparent acrylic wall
– End of filament detector

Despite the cube shape of this machine, it is not a CoreXY, but a Cartesian, if you are looking for a CoreXY printer you will have to look at the Ender 6.

On paper this printer is quite interesting, its structure should allow fast printing, and its walls allow the printing of certain types of filament such as ABS.

Unpacking and assembling the Sermoon D1

The Sermoon D1’s box is imposing, and quite heavy, the package weighs over 26kg!
When unpacked, the components of the structure look very good, it gives the impression of a high quality machine. Given the size of this machine, it is not pre-assembled.


For the assembly, count 30-45min, nothing very complicated, a few screws and some covers, the longest part will be to fix the walls! (which I didn’t install right away for my first tests).

Once assembled, this machine really looks good! I really like the design with a very nice finish.


First impression with the Sermoon D1

Before launching the first print, it will be necessary to check the set of eccentrics, the tension of the belts and to adjust the plate, this machine is not equipped with a self-levelling sensor.

The adjustment of the plate is done with an A4 sheet, after having launched an auto-home, it will be necessary to check the distance between the nozzle and the plate at the 4 corners of the plate, as well as in the centre, this adjustment will be done using the wheels present under the plate.

Once the tray is set, and other checks done, it’s time to start the first print! I strongly recommend printing a test model on the SD card supplied with the printer.

Here we go… and here is the first print with the Sermoon D1, in the process of being finalized, it’s a “torture test” allowing me to test different print settings, the rendering is really clean.

I could see during this impression that this machine is quiet, much quieter (ventilation wise) than other older Creality machines I tested so far, which is really nice

Prusa Slicer configuration for the Sermoon D1

Concerning the slicer, you can use the slicer of your choice, for the moment it will be difficult to find a pre-configured profile, on Cura for example, as the machine has not yet been integrated in the list. Don’t panic, you can start from a generic profile (for a CR-10 for example) by modifying the size of the plate, and also by adjusting the retraction, 1mm will be enough for this Sermoon D1 in direct drive



First impression with Prusa Slicer

Here is my very first print, with the filament supplied with the machine (small 250g spool), with a layer height of 0.16mm, the rendering is really clean with this default profile (or almost), so I will be able to continue using this profile for my next prints.

Here is my second print, still with a layer height of 0.16mm and still the same filament. The rendering is just magnificent! You can hardly see the print layers on this model.


For the next print, I kept the same settings, using Ariane Plast’s filament, black metallic, with a very nice rendering too.

Here are some other prints made this time with the new range of HP filament from Creality. No defects on these 15 to 20 hour prints.


Finally, here are some other prints made this time with Eryone filaments. Always with a very nice rendering, and without any failure of printing until now, I did not need either to redo the adjustment of the plate since the initial setting.


To conclude and give my opinion on the Creality Sermoon D1

I really like the design of this machine, it seems very robust, it will be complicated to move, the machine being imposing and heavy.

This Sermoon D1 is much quieter than the other Creality machines I have tested so far, especially with the ventilation, which is really nice, you can work next to this machine in complete peace

As far as print quality is concerned, nothing to say, it does a very good job, with 3-4 different brands of filaments, and almost 150 hours of printing for this test, I did not encounter any major problems.

The printing area is smaller than a CR-10, too bad I would have appreciated a 300×300 plate on this machine.

I haven’t tried printing ABS with this machine, to see the efficiency of the box, I’ll update the article if I get the chance, but to be honest I rarely print ABS.

For TPU printing, I just received a spool, so I should be able to test soon, and see how this direct drive extruder handles flexible filament.

This is a machine that I could recommend without hesitation, just wait for the stock!
