Cool, but aren't the tips of the nose ridge unsupported like that?

I remembered another thing I didn't like about the model from Skynet2029: the various gaps weren't widened, which means that after painting, most of the gaps and joints get filled with paint and become significantly smoothed out, and some even disappear completely.

This is not a Skynet 2029 model.
It is a photogrammetric model of the HCG skull.
It is still a test and the thickness will be corrected later.

What printer did you use ?

What printer did you use ?

ELEGOO Saturn 3 Ultra 12K Resin 3D Printer

 

[Too Much Garlic]

A 12k one? Cool. That should be able to print the grooves perfectly... I would think.

What layer height did you go with?

Wish my Phrozen Sonic Mini 8K could get the 12k upgrade like its larger cousins got, but Phrozen sadly don't seem to want to make it for that one.

It is being tested at 0.05-0.01mm with different exposure times.
I forgot to put anti-aliasing in the first one.
At 0.01mm, the print time is incredibly long.

My old experiments. Used water-washable dental resin. When I have some free time, I'll try to print a new model.

What do you use for paint?

 

[Nokitten]

What do you use for paint?

Here are just some of the paints I tried. I can't say exactly which pair gave the best result. I need to try again. The most important requirement is to achieve an ultra glossy mirror black surface. Until you do this, do not try to paint metallic pigment on top, otherwise it will not look like real metal. I tried many black glossy paints, but only few gave a mirror surface, with the right pressure and proportion of solvent.

 

[Nokitten]

It was a very long test.

Thank you very much.


I found an interesting video.
How on earth is this done?

What paint was used on the chromed skull example above?

 

[ZeroSum]

Hydrochrome, according to the comments in this video from the same people:

A commenter on one of their other videos claims it is "silver oxide in amonia".

3D printing continues to fail.

Bummer. Wish I could help. Seems like an exposure time issue.

I got all my knowledge from watching Dennys Wang videos on youtube.

I could be wrong, but it looks like low-quality resin.

Maybe my settings are not good.
I am making test prints with different settings.

Check out the Dennys Wang videos on exposure time calibration. They may help.

The long toothed ones look like they may also have an issue with the strength of the supports.
