water damage on 3d Sandstone print

Hi Guys,

I have noticed some water damage on a 3d sandstone print. Any ideas for ways to treat this?

cheers

Did it come like that from SW or did it happen after you got it? The material description for sandstone mentions that exposure to water will fade the colors. Sorry to hear this happened.

Oh No! Time to upgrade to coated to add some protection.

No it was definitely post production. Water from an partially opened window. Not a lot of water though. Anything to do post damage?

The only ways I can think of aside from reprinting would be to dip the whole thing in water to cause the whole thing to become faded. Or, get some acrylic paints and an airbrush and try painting the effected areas.

If you took pictures of the damage and posted those it might help to figure out other options. On the other hand, maybe Shapeways will reprint it for you if Shapeways happened to be in a philanthropic mood.

Hi Guys, see pic attached. Its a shame we just published an article in Hydro International talking about 3d print for science communication and promoting what we did with shape ways help (see attached). Any philanthropic help would be appreciated

This is great; I love seeing both Blender and 3D-printing being used in the service of science!

That said, I think your most cost-effective option would be to find an experienced artist (maybe an art restoration specialist from a local museum?) who could match the color and fix the spots. It looks like a huge print and I'm sure it wasn't cheap.

Not sure you'd need a restoration specialist if the affected areas are just the rugged green surroundings of the measured observable ? (Though if shapeways happens to be in a philantrophic mood, I have a few water- or tea-stained lecture props lying around too )
And get your department's machine shop to build you a showcase for that really nice model...

My impression was that the spots in the purple/blue areas are the problem.

Yeah, I'm seeing some spots in the water area too. One advantage you'd have if the spots are just in the water area and it is in fact flat then one method of correction would be to color inkjet print the same projection at the same scale on paper and then cut along the shoreline and glue it in place. For the gluing it down part I'd use a UV curable resin so that it could be positioned perfectly over the time period needed and then hit it with UV light to fasten it in place. Well, that is, if you could find printing paper that could transmit enough of the UV light. Or you could use visible light curable resin and do it in something like red light to see what you were doing.

Hmmm.. I never seen that happen in the forum before. When I posted the link to the image it appears in the forum rotated 90 degrees counterclockwise.

@Ontogenie: you are right of course, silly me. Perhaps the perfect place to put a legend then ?

(Just had another $50 of "lecture damage" to an object from our private collection, though not to a 3d print this time. I swear we were not that clumsy in our day)

We're all gonna get sucked in!!! OH NOOO!!! HAHA!
