Pick one . It doesn ' t matter . <| sep |> was done on a 12 x 12 Polished Granite tile from Home Depot . I charged the client CAD $ 100 for it , but that was a special price . My normal charge for a piece like this would be between $ 150 and $ 200 . It took 45 minutes to engrave from a raster file . A similar sized piece of wood done with the same level of detail from a raster file wouldn ' t take much less time . I generally charge $ 1 per minute for laser time , so there ' s $ 45 in lasering time alone . However , you ' ve got to understand that the actual lasering time is just a small part of the cost . One off jobs are expensive . Graphic work and the preparation of the material for engraving including getting it positioned in the laser correctly and in some cases construction of a jig to hold odd shapes can easily take 2 to 3 times longer than the engraving , and this all has to be paid for by someone .
