Sandblast vs laser engraving on trophy.
Laser etch vs sandblast granite.
Sandblasting involves the use of compressed air to shoot small sand particles at high pressure at a surface.
There are a few reasons for this.
The laser etching process removes the polished surface of the granite using a high powered laser to show the unpolished granite beneath in varying depths to create the image.
A template is designed first then it is sent to the automatic engraving device where it guides the laser on how to cut the granite surface.
This erodes away the surface and is considered one of the most effective methods for engraving granite.
It s particularly well suited for lettering and can be used for both light and dark colors of polished granite.
As with sandblasting etching reveals the unpolished layers underneath and shapes them into exact designs.
Laser etched designs are done with the use high tech laser etching cnc machines.
Etching removes the surface layer of granite with laser technology.
The darker colors are better for laser etching with dark black granite being the best.
Marble used to be the most popular stone for graves but today it is granite by far.
We use our trotec speedy 360 co2 laser to etch 12 x 12 granite tiles individually then combine them together on a piece of 48 x 24 sheet of plywood.
