Here is my latest creation. The carving is called a Lithophane. In the first picture you can see that it is a reverse relief carving. The darkest details are raised in the design The material is 1\/4 inch thick Corian produced by DuPont. Its the stuff from which counter tops and wall covering is made. As it turns out, it is very easy to engrave.<\/p>\n

The second picture is the same carving with back-light. As you can see, when illuminated from behind, it shows a very high detail gray scale photograph. You can even see the reflection in my glasses! The detail is outstanding.<\/p>\n

In this example the photo area is about 4 x 5.75. Just the right size for the CnC Taig Micro-Mill. I don’t have a step-by-step example in my hobby web site yet, but I will soon. Probably this week end. I’ll post a link here.<\/p>\n

\"\"What is hard to believe is all I used was two ball end mills to machine this picture. The first was a 1\/8 inch mill for roughing out, followed by a 1\/16 inch mill for the finish pass. That was almost 1000 lines. Total machining time was about 2.5 hours.<\/p>\n

As promised, The Hobbyist Machine Shop <\/a>has the lithophane making process in the web site. From the menu bar select “Projects” then select “Lithophane” from the drop down. Enjoy! ~ Dan’l<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
