It won't let me choose more than 20 layers at .1

Unless there is more than one litho generator on thingiverse?

lithopanes are all about contrast and grey scale. so the sharper the image the better quality lithopane will have

invert colors makes it a negative so when back lit the darks are dark and lights are liaght. the Thingaverse one should print 3mm thick using 30.1mm layers for best results

I am not convinced that invert colors does anything, I tried to get a decent print of a pic of my daughter and it keeps looking like an x-ray no matter the setting, I think the background might be too dark, it is making the background thick and my daughters image thin for some reason.

It generates it to about 2.2mm thick at the border

My settings for the customizer are as follows; http://www.thingiverse.com/apps/customi … g_id=74322

Standard Photo
Vertical Orientation
Large Pane Size
Invert Colors (this is important, otherwise it looks like an x-ray when you print it)

Include Hole
Hole size 10
Layer Height .1
Number of layers 20

When I sliced it in XYZ I set it to;

Solid 90%
Normal Shells
.1 Layer height
Standard Speed

scotthay what is the thickness of the picture you made?

That's pretty good, I'll have to check into the thingverse thing. I kept having a problem with the xyz ware freezing up when I tried to open the .stl files generated by that freeware program, although autodesks programs opened then just fine. I downloaded the demo for photo to mesh, and it seems to work alright, the xyz ware reads it, just have to try a test print tomorrow when I get home from work.

Here is my first attempt. I used the generator on thingiverse to make this, then used stock XYZ software/firmware to slice. Printed with XYZ white. This is my 2 yr olds school picture from this year. I thought it was a complete failure until I put it up to the light. Doesn't look like much until backlit. Didn't turn out too bad for a few minutes of work and a couple hours printing.

thingaverse has a custmizer for lithopanes just upload pic for stl even different shapes availible. takes long time to slice and print and must use thin layers solid infill for good results.

The one I created and sliced with stock XYZ software actually looked better before running it through netfabb. I haven't printed one yet though. I will try to pick up some natural filament and see how they print.

If you're having trouble with the file, don't forget to try running the STL through
cloud.netfabb.com

A lot of software has crummy STL generation that makes it hard for the slic3r to deal with...Though, if you're using repetier that should often be noticable now (it has somewhat recently had basic file problem detection.)

The slicing process however is a trouble... XYZ firmware does a really messy path, Cura works better, however it is still far from being perfect. I suggest that you use some translucent filament, or at least natural ABS. I tried with white and blue original XYZ filaments, and I really wans't satisfied.

I'm wanting to make a picture box that has my nieces pictures on it as a gift for my mother for Christmas, something I think she'd really like, ya'know? I played around in the program last night, but haven't put it into xyz yet, I've also got some of the 113d software, so maybe that'll slice better? If I can't get this to work, maybe I can get 123d catch to work and just print some statutes of my nieces out instead.

These are cool, I just played around with that software. They definitely don't slice well in the stock XYZ software though.

A freeware program called bmp2iges-2d to 3d converter.
