Rubber spray

Hi Domenic

In this forum https://www.rmweb.co.uk/community/index.php?/topic/108310-darkly-labs-emblaser-affordable-laser-cutter-review/page-48 you are talking about a liquid rubber spray to laser acrylic surfaces.

Can you tell me please the laser parameters you have set (move speed, power, no. of passes, fill-stepover-crosshatch)?

Thank you very much for your information.

Greetings Salvi

Hi Domenic

Thank you very much for the settings.



That link doesn’t work for me.  What spray are they talking about?


The link is not working for the moment, because the operators of the forum makes some updates to the server.

It is a rubber spray that is applied to the surface of acrylic, and then it will be possible to laser on the surface.

I have just made a try and it actually works quite well. I am currently experimenting with different settings. I will post the results here afterwards.

Here some links to rubber spray:





I hope that site comes back up. It was a good source of information.

In the meantime, here are some photos of how we use the spray to engrave onto clear acrylic and glass.








I have made some test with acrylic but the results were, for me,  not satisfactory. Following are some acrylic tests with one coating rubber spray:


after that i tried with glass. that was awesome :slight_smile:
