1 - The Ceramic Tea Cup

The Sculpfun S9 laser engraver is capable of engraving directly on ceramic tea cups!

You an easily engrave a small vector image on a tea cup to make it your own.

The settings we have used for this material:

  • 300mm/min and 100% power

But you always need to adjust the settings according to the results you are seeing.

Laser engraving ceramics produces very deep engravings as the surface cracks under laser light. The result is permanent and will not scrape off.


2 - Laser Engraving Glass

Transparent materials are very difficult to engrave with laser engravers. This is due to the fact that diode laser engravers produce laser light that is in the visible light spectrum. This means that whatever looks transparent to you, will not absorb the laser light and there will be no effect. The same applies for white and light colored surfaces. They will reflect the laser light away.

In contrast, the CO2 lasers wok in the infrared spectrum and this means that their laser light is basically just heat which absorbs in almost all materials. But the CO2 lasers are big and much more expensive than diode laser engravers.

For mitigating this transparency problem, you can paint the surface black with a cheap spray paint or watercolors, or even a black permanent marker just to give the laser light something black to work on. You can remove the paint after engraving with acetone.

Then you can get the results like on the photos below.

The engraved surface is similar to the sandblasted surface. It is a rough surface that is permanent and will not brush off as the laser makes little cracks on the surface.

The settings we have used for this material:

  • Fill+Line engraving
  • Crosshatch infill, 500mm/min, 100% power
  • line after fill (outline of the letters): 300mm/min and 100% power

But you always need to adjust the settings according to the results you are seeing.

3 - Making Custom Shaped Stickers With Laser Engraver

If you want to up your game with custom stickers, look no further!

With laser engraver you can engrave the text and images on the sticker and then cut out the ouline of your desired shape.

You just need to dial in the power right.

The settings we have used for this material:

  • text engraving: 600mm/min and 15% power (so it does not burn through the paper)
  •  outline cut-out made at 600mm/min and 100% power

But you always need to adjust the settings according to the results you are seeing.

4 - Laser Engraving Stainless Steel

Sculpfun S9 is a very powerful laser engraver that can engrave the stainless steel directly! It is the only 5W laser engraver we tested that can do this.

To demonstrate this, we have painted just a part of the engraving black using a permanent marker to see if there is any difference as the stainless steel is quite reflective.

And to show the durability of the engraving, we tried to scrape off the engraving with sandpaper. The engraving held up quite well! You can see the amount of sanding done in our Youtube video.

The settings we have used for this material:

  • 200mm/min and 100% power

But you always need to adjust the settings according to the results you are seeing.

5 - Laser Engrave Custom Jar Lids

If you want to impress your friends by giving them a professional looking jar of homemade jam, this laser engraver is for you!

You should check the cool tip in our Youtube video on how to align the jar lid under your laser to get a perfect alignment of the engravings every time!

The settings we have used for this material:

  • 200mm/min and 100% power, but I figure it could go faster than this and still work well

But you always need to adjust the settings according to the results you are seeing.

6 - Laser Engraving Granite Stone

Stone is something you would not think its possible to laser engraver, but it is and it produces great results!

Smooth and single colored stone works the best. The black color is the best, but it also works on some white stones. But it does not work on marble stone very well. You need to try it and see.

The settings we have used for black stone:

  • Photo engraving: 2400mm/min and 100% power, Jarvis mode
  • Tombstone engraving: Line+Fill, crosshatch infill 0.2mm line spacing 2000mm/min 100% power for fill and 500mm/min and 100% power for outline after filling.

But you always need to adjust the settings according to the results you are seeing.

We also tried to engrave ceramic tile and the result was also good: 500mm/min 100% power crosshatch infill with 1mm spacing and 200mm/min 100% power for outline.

7 - Making Stencils For Spraying Paint

You can download some stencil font like this one and easily make a stencil out on a masking tape or a piece of paper

It is a cool trick to make some awesome stuff!

600mm/min and 100% power is more than enough for cutting the tape.

8 - Laser Engraving And Cutting Real Leather

I had a old piece of leather which was probably older than me and I tried to engrave it.

Laser engraving leather stinks A LOT! You need very good ventilation. After engraving the pattern is a little bit burned but if you wash it and use a brush to remove charring, the finished effect is a very nice and deep engraving which looks awesome!

The settings we have used for leather:

  • Line+Fill, crosshatch infill 0.1mm line spacing 2300mm/min 100% power for fill and 600mm/min and 40% power for outline after filling.
  • for cutting 600mm/min 100% power and 13 passes for this old 4mm thick leather

But you always need to adjust the settings according to the results you are seeing.

9- Laser Engraving Chromed Surfaces

The theory is the same as laser engraving glass.

You need to paint it black first. Then, laser engraving burns away the shiny surface and leaves a very nice and permanent engraving!

The settings we have used for chromed surface:

  • Line+Fill, crosshatch infill 0.1mm line spacing 400mm/min 100% power for fill and 100mm/min and 100% power for outline after filling.

But you always need to adjust the settings according to the results you are seeing.

10 - Engraving The Backside of The Mirror

You can’t directly engrave on the mirrors shiny side. It is also not recommended as the light can reflect back in your laser module and can damage it!

Mirrors are engraved on the rear – grey side.

PRO TIP: You must not forget to mirror the image else the text will be backwards  on the other side 🙂

You can get a very cool effect if you put a light behind the mirror as the light will shine through the engravings making a very cool efect!

The settings we have used for laser engraving mirror:

  • 220mm/min 100% power

But you always need to adjust the settings according to the results you are seeing.

  1. Nice article, thanks for your work ?
    I hope that under “Stickers” you don’t mean vinyl (you better specify that!). You surely don’t want anybody to get hurt or anybody’s laser to be ruined, right?

  2. I have a S9 and I love it, but you are saying that nearly every one of these materials require the laser running at 100%. I heard that it isn’t good to running it at 100%, so who is correct???

      Running at 100% will probably not affect the life span of the laser significantly, unless you use it A LOT.
      You can probably engrave most of this things with only 90%, but you need to go slower. Our power and speed settings are not ideal and can be improved significantly with some more experimenting.

  3. In what cases, to engrave a photograph, it is necessary to convert it as a negative or reverse photograph in the software? Thanks.

      You would need to invert the image if a engraved surface becomes lighter colored than the non engraved.

  4. Are the files still available? I get a 404 error files not there.

  5. Thanks for the article. Do you have any experience with engraving soap? What would be recommended settings in terms of power and speed?

      Never even though of that 🙂
      I suspect low power and speed would melt it nicer. But its just a guess.
