First successful lithopane

(1/3) > >>

Gadget:
I cut this out of 1/4" corian today with my CNC table using a rotozip as a router.
This is my granddaughter Lucie. The first photo shows the cut in normal light. The second one is backlit. The plan is to put this along with one of my grandson in a lamp as a Christmas gift for my Son and Daughter in law.

Wait, so that is the same piece? Just different lighting?

That is very cool. Care to show us how it is done?

Gadget:
Yes it is the same piece. Here is a description of the process.
I used my home built CNC table with a rotozip. Made a rough pass with a 1/8" ball mill .08 deep from 0. Then did a finish path with a .041 tapered ball end mill with an overlap of cut by 90% (only increased 10% for each cut). This was done .10 deep from 0 which was set to the top of the piece. The software used to generate the code was Vectric PhotoVCarve. The image was set to reverse the cut so the dark portions are thicker letting less light through. The whole purpose is to take a photo and engrave it onto opaque plastic so when backlit it looks like a photo. Then the panel can be put in in a lamp or shadow box for viewing.
I took some video of the cutting but have to edit it before posting.

Brass_Machine:
Thanks! That is very neat. Looks like a photo with the back light.

Here is a short video showing how the lithopane responds to light.
