Hello!


Thanks for taking the time to read my post. I was wondering what the depth of a typical engraving is? Is it deep enough to pull letters off if resin or a casting material is poured on it?

Thanks in advance for your help!

Grant,

If you are using a spindle and the letters are big enough to be able to use a flat bottomed endmill style cutter then you could achieve excellent results with casting letters.

However;
The typical engraving points only have a 0.004" flat on the bottom so the surface finish on any letters cast this way would be ridged.
Lasers also have a typical spot size around 0.004" and again ridges would be present on the casting unless the laser could be accurately set (perhaps out of focus) and the speed kept at a constant velocity to preserve depth.

Tweakie.

Thanks for your response!


I am looking to have mostly rectangular shapes. I was hoping to make a mold to take surface detail. It would be a mini brick wall.


Any engravers in the southern california area?


Thanks,
