Photograph in a bubblegram?

[jsmoove]

What is the highest resolution image you could technically get in a bubblegram?
I noticed most 3d laser engraving machines go to 1200dpi.
So if one had a glass cube of 3" x 3" x 3", what would be the max resolution in pixels of an image that could be written?
How many shades can be achieved?

Also, what the heck is going on here?

It is not laser-engraving. But instead -crystallisation.

The glass is turned from an amorph into a crystalline state.
The technique likely is similar to setting-techniques in 3-D printing.

@AgX Ah! I didnt know that!

 

[jsmoove]

@AgX Is colour possible in the future?

 

[AgX]

First time I learn of such. Maybe if the glass is doped.

 

[jsmoove]

@AgX Its weird, in the video, it looks like the reflection is on the inside of the cube like a mirror. I dont quite understand whats going on.
By doped you mean ?

 

[AgX]

The reflection IS inside the cube.
By technics hinted at points within the glass are transferred into crystalline state.


With doped I mean added substances to the glass. In general it is known that by applying energy minerals can be made to change their colour (eg. jewellery, radioactive glass). By means of special composition of the glass the resulting colour might be controlled.

This is an ad-hoc answer without any contemplation, on an alien field.

I find it very interesting. I wonder what kind of mixture or what kind of glass would exhibit these properties.
If it is possible to create a 3d multicolor image inside glass/crystal.

Hi jsmoove
I have no clue what those things are or what they are doing or how they made them but they look kind of fun
If you have access to a 3D printer you can make lithophane images

good luck !

@jnantz Hey, yeah I was thinking you could essentially make a lithophane but instead inside of glass, as a heightmap. 3d crystal laser engraving seems to be able to do shades, I havent found a service that can do resolutions of 1200 dpi, that seems to be the limit according to google. Wouldnt mind trying it out to see what it looks like, but I'd like to do as high of a resolution as possible

Lithophanes ARE a "heightmap", a relief.
However the trick is to present the viewer the plane side, not the relief. By strong backlighting a transparency appears.

Does anyone know of any cost effective DIY ways of doing a bubblegram ?
Seems like all services are priced ridiculously.
Seems the common material for subsurface engraving is Borosilicate glass specifically...
