Once my dimensions were set, I exited the 3-D mode and then brought in a vector line of the file I was going to run. With both items selected, I went to the advanced tab to select the 3-D Relievo Engraving option (please note that your machine settings will differ based on brand). Once in the 3-D Relievo Engraving page, I finished setting up the file. I double checked that my Z-depth was accurate, and then set my precision, engraving, and polish settings. For the engraving, I knew that I needed depth, so I used a smaller hatch at .01mm, 90 power, and 60 frequency. The only thing that changed for my three fills was the angle of the engraving — by switching it around, I was able to avoid unwanted lines. Next I set my polish fills. They were set to run on Pen 2 with a larger hatch spacing, more speed, less power, and a higher frequency. With a quick red outline check to ensure my placement was correct, I was ready to hit go and watch the 3-D file be built out with every pass. I hope to dive more into the STL file creation, push the limits of 3-D engraving, and expand what all items I can engrave them into. I hope this has been insightful and helps encourage everyone to push the envelope.

I am amazed at how easy this was to accom- plish. I have never been a 3-D person and never attempted to use 3-D files before this, but on my third try, I feel like I can now repeat my results thanks to the laser software making it easy. Since my laser is a 3-D galvo, I am able to load an STL file and have the laser engrave the layers while my galvo mirrors adjust the focus to allow the 3-D depth to be engraved. To accomplish this ornament's engraving, I started out using Aspire to edit and manipulate the file. From Aspire, I saved the file as an STL file and was then able to switch over to the Radian software to finish the setup and engraving. As mentioned, this was fairly easy, so the steps are a little short. I created a new file, selected the 3-D option, and then when my 3-D page opened, the STL option became active. By clicking the STL option, I was able to bring in my file and then using 3D-Transform, I was able to set my dimensions and Z-depth. When following the correct guidelines and steps, it is possible to create a 3-D effect using a fiber laser. Since my laser is a 3-D galvo, I am able to load an STL file and have the laser engrave the layers while my galvo mirrors adjust the focus to allow the 3-D depth to be engraved. Here you can see my engraving settings: I used a smaller hatch at .01mm, 90 power, and 60 frequency. Once again, consult your manual for your particular machine. From Aspire, I saved the file as an STL file and was able to switch over to the Radian software to finish the setup and engraving.
