Metallic paint questions....

[CPDDET]

Have several smaller parts for my current build that were made by 3D printing. Would like to paint these to look like metal (brass, bronze, chrome, aluminum etc.) I've heard that Velliajo makes a good product but is difficult to work with. Also have seen paint pens for this purpose. 

Asking for advice on a good product and  process.

Vallejo do various metallic acrylics for airbrushing and personally I haven’t found them at all difficult. They spray just like any acrylic.

 

I’m a big fan of acrylic metallic artist pens. For small parts I much prefer using a gold pen than spraying. It lays a thicker coat which seems to make the finish look more metallic. I’ve also used a chrome pen on model car parts, to good effect.

 

nb. Pretty much all my model parts are 3d printed but I don’t think that has any real bearing, the metallics work on many types of material.

As for gold and copper I can recommend paints shown on the pictures. I was pleased with the results.

Brand?

Pentel, Zieler, whatever they have in your local art shop or stationers should do the job. They are relatively inexpensive.

I've used the Alclad line of airbrush metallic paints with generally good results: https://alclad2.com/

 

However, they don't seem to have brass or bronze, though I know their "pale gold" produces a really nice finish.   The highly shine colors are sprayed over a gloss black base.....I'd recommend against the alclad gloss black base and use the Tamiya LP-1 gloss black lacquer.  I tried the alclad gloss black base and it seemed to never completely dry/cure.

   

AK Interactive also make both metallic paint and a few metallic paint markers.  I've heard good things but never used either.  https://ak-interactive.com/

Metallic paints have several different types. The differences among pigment, dye, mica, and metal powder determine the characteristic of metallic paints. This knowledge will help to adjust your metallic paint properly.

I see. So the question is, what is a proper primer for 3D printed parts. I apologize for misunderstanding.

So my plan right now is to use Alclad Polished Brass over Alclad Gloss Black Base on the prop shaft support to match, as close as possible, the brass prop and shaft.

I want to use Alclad Dull Aluminum for the anchor windlass, running light housings and vents but not sure what to use for a base coat. Any advice?

Interesting....the polished brass is not listed on alclad's web site but it is available from other sellers.  I'd reconsider the alclad black base, see my comment above, though maybe you will have better luck with it.  I've not used the "dull aluminum" but the regular aluminum and semi-matte aluminum both produce a nice finish.

 

For the non-polished Alclad metal colors, I've just used generic medium gray primer.   I tend to use splash paints primer but others will likely work as well, including Alclad's gray primer/microfiller.

Ak´s Extreme Metal range works also very well, except for their black base, which like Gary mentioned never cures properly and stays tacky. Like Gary, I use Tamiya LP1 gloss black as a base for high shine finishes.
Your anchor windlass would be best painted with dull matte aluminum and AK has brass and bronze in their portfolio as well. They spray as perfect as Alclads, but are a bit more durable, when it comes to masking on top. Chrome and polished aluminum is a tad shinier with Alclad, but it´s only a fraction.
