The Creality Ender 3 S1 is now official

Read the update.

The Creality Ender 3 and its successor, the Ender 3 V2, are two of the most popular 3D printers for those creating their own, customized ESPHome projects. The upcoming Ender 3 S1 is an upgrade to the Ender 3 V2 and — this is where it gets interesting — is much more user-friendly. Not everyone wants to spend a weekend putting together a 3D printer before a project can be printed. If that strikes a chord, this addition to the Ender 3 family might just be what you are looking for.

  • Direct dual-gear extruder: The Sprite is lighter and features less inertia and more precise positioning, supports PLA/TPU/PETG/ABS print filaments.
  • Dual Z-axis: With a Z-axis dual-screw and Z-axis dual-motor design, the Ender 3 S1 works smoother and more synchronously to lower the possibility of lines and ridges on the sides of your print, thus improving the printing quality.
  • CR Touch automatic bed levelling: 16-point automatic bed levelling technology saves you the trouble of manual levelling and makes levelling simple and easy.
  • PC spring steel printing platform: The innovative printing platform is a combination of a PC coating, a spring steel sheet and a magnetic sticker, the model can be sticked to the platform or take off more easier.

The Ender 3 S1 is not official yet, nor do we know of any definite release dates, though it expected to go on sale around the turn of the year. I sourced the information provided in this article from a video uploaded by the 3D printing shop AzureFilm and a subsequent written article. While the video has been taken down for possibly violating an NDA, the article remains online until now, for reasons unknown to me.

Assembling the Ender 3 S1 in 10 minutes

For those out of the loop, the ever-popular Ender 3 and Ender 3 V2 do not arrive fully assembled at your doorstep. By doing so, Creality can keep the prices low. It will take you a couple of hours of work, before you’ve got anything resembling a 3D printer. It doesn’t stop there. Once you have put your machine together, you will need to level the bed if you want a chance at getting good prints.


The Ender 3 S1 should be much easier to assemble, with Creality claiming just ten minutes of work will do. It will also come with a CR Touch , Creality’s automatic bed leveller, preinstalled. Although this feature isn’t unique to the model, and you can easily add a CR Touch or BL Touch to your Ender 3 and Ender 3 V2 retroactively, the S1 spares you that work.

The individual parts of the unannounced Ender 3 S1

The Ender 3 S1 replaces Bowden with direct drive

The extruder is what pushes the filament to the heated nozzle, where it melts, and gets extruded. Fused deposition modelling (FDM) 3D printers use one of two possible extruder types: Bowden or direct drive. It is undeniable that direct drive extrudes are superior to Bowden extruders, as the path the filament has to take is much shorter. They are more likely to give good results, and can provide a higher resolution. Manufacturers still use Bowden extruders in cheaper 3D printers, due to their lower price-point.

With the Ender 3 S1, Creality is finally employing a direct drive extruder in place of the Bowden extruder found on the Ender 3 and Ender 3 V2. This upgrade should give the Ender S1 the ability to create nicer prints. As with most of the upgrades mentioned in this article, it is possible to fit the Ender 3 and Ender 3 V2 with a direct drive extruder of your choice. But if you go with the Ender 3 S1, you won’t face a minute’s work.

No more CR Touch retrofitting

Another addition that will make life easier is the preinstalled CR Touch. This little device allows your 3D printer to automatically level its bed, making sure everything is set up correctly before printing. Compared to auto-levelling sensors with a plastic tip, the CR Touch, with its metallic probe, is more durable and faster, as it uses an optical sensor.

Creality Ender CR Touch

  • Metallic probe: The CR Touch has a positioning accuracy of ≤0.04 mm and can be reused for more than 100,000 times
  • Compatibility: Ender 3 V2, Ender 3 Pro, Ender 3, Ender 3 Max, Ender 5, Ender 5 Pro with 32 Bit V4.2.2/V4.2.7 mainboard
  • Easy to install: Download and copy the CR Touch program to an SD card and power on the 3D printer to update it

Another sensor included in the package is one that checks if your filament has run out. Filament running out during a print has been the cause of many frustrating moments, as it frequently means you will need to start from scratch. The filament run-out sensor on the Ender S1 will signal to the printer that it should stop once it detects that no more is coming. You can then install a new spool and the printer should continue where it left off.

Two motors to move the Ender 3 S1’s printing bed

The printing bed on every 3D printer, which has once again been improved on the Ender 3 S1, is moved back and forth by a Z-motor. Or, as is the case on the Ender 3 S1, two Z-motors. The issue with having just a single motor, which is the case on the current Ender 3 printers, is that the surface can begin to sag, once a print reaches a certain weight. The Ender 3 S1 with its dual motors, which each drive a threaded rod, should have no such problems.

Creality Ender 3 V2

  • Quiet operation: The Ender 3 V2 features an updated motherboard with silent TMC2208 stepper drivers
  • Easy control: The new LCD and operating system, greatly improves the user experience
  • Better adherence: The carborundum glass platform enables the hotbed to heat quicker and prints to adhere stronger

The build plate, which is on the printing base and ensures that the print adheres nicely, has been improved with a PEI sheet. PEI requires no preparation before use°, or so it is claimed, and has all the properties you would be looking for in a build plate: radiation resistance, high and low-temperature resistance, high-temperature stability and high wear resistance.

When can I buy the Ender 3 S1 and how much will it cost?

The Creality Ender 3 S1 should make its first appearance on shelves towards the end of this year or early next year. It has been listed for €359, which will likely translate to US$350. With the Ender 3 V2 sometimes going for as little as US$250, the Ender 3 S1 is in another price class. However, were you to upgrade the Ender 3 V2 to the Ender 3 S1’s specifications, you would likely be looking at a similar price.

Why is 3D printing important to the Home Assistant community?

The Home Assistant community is made up of people from all walks of life. One thing many have in common is the love for creating and customizing hardware. ESPHome has been something of a gateway drug to the world of cheap electronics and custom-builds. A 3D printer allows you to make your creation look somewhat professional, and it expands the possibilities of what you can do.


Update: The Creality Ender 3 S1 is now official

Creality has officially announced the Ender 3 S1, which will ship early next year. It has been revealed that the direct dual-gear extruder has been named Sprite.
