The Anycubic Photon Mono M5 and M5s are both medium-format resin 3D printers known for their affordability and decent print quality. Here's a breakdown of their key differences to help you choose:

**Printing Speed*

* **M5s* Significantly faster printing speeds due to a more powerful light source and optimized slicer settings. It boasts an average printing speed of 105mm/h.
* **M5* Offers standard printing speeds, typically ranging from 20-50mm/hr.

**Print Quality*

* **M5* Generally considered to produce slightly sharper prints, especially when using high-quality, detail-oriented resins. This is likely because of the slower printing speed allowing for more precise curing.
* **M5s* Prints may have a slight trade-off in detail for the sake of speed. However, the quality is still good for most applications.

**Resolution*

* **Both M5 and M5s* Share the same LCD screen with a resolution of 11,520 x 5,120 pixels, resulting in an XY resolution of 19 microns.

**Other Features*

* **M5s* Includes auto-leveling for a more streamlined printing process. This ensures the print bed is perfectly level for optimal print quality.
* **M5* Requires manual bed leveling, which can have a learning curve but offers more control for experienced users.

**Here's a quick table summarizing the key differences*

| Feature | Anycubic Photon Mono M5 | Anycubic Photon Mono M5s |
|---|---|---|
| Printing Speed | Slower (20-50mm/h) | Faster (105mm/h) |
| Print Quality | Potentially sharper | Good quality, slight trade-off for speed |
| Resolution | 11,520 x 5,120 pixels (19 microns) | 11,520 x 5,120 pixels (19 microns) |
| Auto-Leveling | No | Yes |

**Choosing Between M5 and M5s*

* **For speed* If printing speed is your top priority, the M5s is the clear winner.
* **For detail* If high-resolution, detailed prints are crucial, the M5 might be a better choice, especially if you're willing to invest time in manual bed leveling.
* **For beginners* The M5s' auto-leveling feature can simplify the printing process, making it more beginner-friendly.

Ultimately, the best choice depends on your specific needs and priorities.
