Today is the first time I’ve tried engraving laser polymer stamps since my first adventures, when power settings were very different. I thought I’d revisit the process using the new settings, and let me tell you they work great!
First off, the settings for Art Stamp Laser Polymer that gave me good results are as follows:
Prepare your file as a raster engrave rather than vector engrave, to get access to the Vary Power function. Do three passes of Speed 1000, Power 100, Greyscale setting Vary Power with a minimum of 1, 225 LPI with a material height of 0.144 inches. Using these settings I created a stamp from an inverted PNG that had a bit of grey around the letters to provide a slight slope to the stamp, which supports the sides of the stamping areas. Note that the typeface I was using was kinda squiggly, so that came out in the stamp:
I did another stamp which shows that you can do quite thin lines with this stuff. Dime included for scale:
So, have at it folks!
