In this review I test the ACMER S1 laser engraver and compare it directly to one of …my professional 24W diode laser engravers.
Despite its very low price, the ACMER S1 delivers extremely sharp engraving results thanks to its ultra small laser spot size of just 0.04 to 0.06mm, depending on the model.
In terms of engraving detail and precision, this compact desktop diode laser performs far beyond what you would normally expect from Diode lasers in general, and especially in this price range.
The ACMER S1 is available in 2.5W, 3.5W and 6W versions.
In this video I test the 6W version, but I also explain why the lower power versions can actually be even sharper when it comes to fine detail engraving, single line fonts and line drawings.
If your main goal is engraving small objects, thin materials or highly detailed designs, this laser engraver is a very interesting option.
This is a small, lightweight and portable open frame diode laser engraver with a working area of 130 x 130 mm. It connects via USB and works with popular laser software such as LightBurn and LaserGRBL. Because of its compact size, the ACMER S1 fits easily on a desk and can even be used on location with a laptop and a suitable 12V power source.
This video focuses primarily on engraving quality.
While the ACMER S1 is technically capable of light cutting with enough passes, this is not a cutting laser. If you are mainly looking for cutting thick wood or acrylic, this is not the right machine.
The real strength of the ACMER S1 is high precision laser engraving.
I also discuss important safety considerations.
The ACMER S1 is an open frame diode laser and lacks features such as a tilt switch, fire detection and an emergency stop. This means the laser should never be left unattended.
In the video I explain these limitations honestly and show how I personally work with this machine in a safe way.
To improve usability and safety, my son and I designed several practical 3D printed accessories, including a print bed and alignment tools.
These files are available for free via my MakerWorld account and can help you get more accurate and consistent engraving results.
If you are interested in fine detail engraving, single line fonts, small text, logos, names or personalized items, the ACMER S1 laser engraver delivers outstanding results for its price.
Even when compared to a much more powerful 24W diode laser, the engraving sharpness of the ACMER S1 is truly impressive.
