A&E JUNE 2018 • 23 Laser Engraving of details that add to the realism of the carving. I used Arial Narrow for the text and drew a few lines to match the mark- ings of actual bolt I was using for a model. Move them to the bolt head. Step 5. Change the identifying mark- ings' color to R:230 G:230 B:230 (10% black) so that they will be raised off of the head. You've just drawn a hex head bolt and washer suitable for relief carving. Step 6 (optional). You can run the graphic as shown in the previous step and it will look like a countersunk bolt. For other projects, you may want the bolt and washer to be exposed. This would require an optional black back- ground. Make any shape you prefer (I made a square) and uniform fill with R:0 G:0 B:0 (100% black). Move it to the back of the page, centered under the washer. Step 7. Open the print menu and select whatever option you have for doing relief carving. The Epilog driver has a 3-D option to check for Raster Type in the advanced options. For an Epilog, the 3-D option automatically defaults the power setting to 100 percent. All you need to do is set your speed — I use 30 for my 60-watt laser — and resolution — I use 600 DPI. Make sure the page and other settings are good and send the job to the laser. Step 8. I suggest carving this from a piece of hardwood. Run the job once and check the results. If it's not deep enough, run a second pass. Once the correct depth is achieved, run a full speed pass to clean off much of the residue. Step 9. Clean the residue from the wood. Relief carving does not depend on burn marks; rather, it's the shading created by light that reveals the dimensions. The wood should be as clean as possible. I use water and a nylon scrub brush to remove the residue. Relief carving graphics are compila- tions of drawn and gradient-filled parts. After drawing and carving the hex head bolt, try Phillips head screws, rivets, and other types of hardware. Once the graphics tools are mastered, more organic subjects can be tackled. In a future issue, Part 2 will cover creating custom, editable, relief carved backgrounds and adding details that bring realism to the work. There is nothing that inspires more awe, in both the artist and the client, than a detailed, well-executed relief carving done with the laser. With a lot of practice and patience, you can create unique, custom work that stands alone and commands premium prices.
