3D Printed Lithophanes

This video outlines my final project for CS656: Advanced Human-Computer Interaction.
After posting this video, I discovered that these are called "Lithophanes." en.wikipedia.org/wiki/Lithophane

and what adjustments would you recommend for FDM printers

[@justinjensen1009]

For an FDM printer, it'll depend on the material you use. You'll likely have lower spatial resolution (since the print head's width is pretty large) and much lower brightness resolution (since the printed layers are thicker and the material is potentially more opaque). I didn't try it on an FDM printer because I didn't think it would work. You should go prove me wrong :)

What filter did you put on top of them at the end to improve contrast?

[@justinjensen1009]

+Tony Buser I guess I didn't make that super clear in the video. I also printed a large hood that fits on top of that little black table. The hood blocks a lot of the ambient light, which improves the contrast quite a bit.

that behind the glass or film you are using a video? 1:48 ?
sorry for my English, I use Google translator

[@justinjensen1009]

It's actually a large 3D printed hood, kind of like a lens hood you'd get for a camera lens. It just blocks ambient light. In theory, you want all the light coming through the back of the lithophane and no light reflecting off the surface.

Hi, what printer do you use in this video? thanks

[@justinjensen1009]

I used the Stratasys Objet30 Pro. The material was VeroGrey.
