New to the forum
Hello, my name is Greg and I am new to not only the forum but also to the entire CAD world. I do have a question. I am trying to mill a pendant using a scan of a fingerprint. I attached a sample print of something I would like to mill. Can somebody point me in the right direction what i should do first. I believe that i have to do something with greyscale and give the image better black and white contrast. Thanks

Greg,
1. you need to export the image in a Bitmap, BMP file from whatever used >
2. open 3d engrave, and import the BMP>
3. this is my step, go to Image, and
a. reduce colors to 16>
b. reduce noise
4. go to shape> convert to polygon>
5. Now you have your converted image>
6/7 If you have to clean up image
8. Save image to reuse later.
Repost if any other questions

- go to shape and register symbol, so you can use again if needed, I save everything, as it takes time to do the work, makes no sense not to save.

Welcome Greg glad to have you here.
Funny how many request I am getting now asking if the 3dwaxmill can carve a fingerprint. The answer is yes.
Here is a 3dengrave file i did for a sample.
open and click on one shape then tab through to see how it was built
Go to Relief / and delete the Relief then rebuild the relief
Let me know if you need some help.

Hey all, I tried to mill Jeff's file of the finger print and this is what I ended up with. I milled my roughing and finishing pass with a .020 flat with Jeff's specs. One thing I might speculate on is that I did not have the mill all the way touching the wax on the finishing pass, it was a tenth of a mm off. Could this be the reason that I cant see the finger print? Thanks

go to 3dengrave, pull down the cutting poarameters and change it to ball, .01mm, fine. hit create tool path, then when it is done File>"output preview, that will open virtual modela, then in VM look for the command that makes the viewed area zoom, it is called "partial zoom' maybe.. then after zooming you can hit the 3d button to see the file from all sides.
I am somewhat sure that the problem is either a too big endmill, or the relief of the file is not set to .05mm.
hope help M
