Topic: Painting ABS Plastic

Is it easy to paint a Solidoodle object afterwards? If so, what paints work best, and what if any techniques?

Re: Painting ABS Plastic

I usually just sand it some with 180-220 grit then hit it with the fusion paint from home depot, haven't done too many things but I think it looks ok.

Re: Painting ABS Plastic

If you primer it then you can use a lot of different paints. The two main brands in my area that I use is either duplicolor paints from the auto supply store and rustoleum paints from home depot. I tend to stay away from any paint that lists acetone as an ingredient, but I have not actually tried them to find out if they will eat the plastic or not.

Shouldn't any model paint work?

Re: Painting ABS Plastic

You will want to get some acrylic paints.

dutchmogul paints his figures without cleaning them up first and they have more of a distressed finish.

I imagine it would be fine. I haven't tried using model paints though as the price for the paints and paint-guns are a bit too high for me at the moment. Can spray paints tend to have just the right amount of a paint I need for most projects anyway. When in doubt just paint some scrap piece you have laying around to see how it reacts to the plastic. I do this also when trying to figure out how the texture of the paint will form depending on how I spray it on, or to see if the ambient temp is too low for painting, (I do most of my model work during the late nights).

nickythegreek, thanks for the tip. I have acrylic paint already on hand. Never thought to try using that as I always used it for painting metal. Gonna try that distressed finish sometime. May come in handy to know how to do sometime in the future.

Re: Painting ABS Plastic

For parts I sell I sand, then acetone, then sand again, paint with filler primer and then top coat them.  I use duplicolor paint you would find at the auto parts store.

Well when my printer actually shows I will be doing some finishing tests, then purchasing an airbrush system and give it a try.

Re: Painting ABS Plastic

I just tried painting a piece to see how it would turn out and I am very impressed with the results. I painted it using BASICS acrylic color paint. I did absolutely no sanding and printed at .3 mm height. I only used one coat and the overall look is great. Towards the top of the print the plastic is so thin that it is a little bit translucent so it looks like the top isn't quite finished but that would be easily corrected with another coat of paint. http://i.imgur.com/obchTfU.jpg

Acrylics tend to work very well.

Re: Painting ABS Plastic

Any other suggestions for paint? I would like to use a paint I can paint brush on versus a Krylon spray paint. I haven't found acrylic paint stays on very well or covers very evenly.

Re: Painting ABS Plastic

For small areas, you can use a sharpie.   The black covers very well and is cheap.  As a cautionary tale, if your layers seem loose (like the adhesion is not good and there's some gapping), there may be some bleed into other areas, but it works well for the purpose.

I'd like to paint in gold, silver, red, blue, and other more exotic colors.

Re: Painting ABS Plastic

There are metallic paint pens for kit model painting.  I remember buying one a while back for one of my Robotech model to paint the metallic pieces silver.

Check these out:

Re: Painting ABS Plastic

Do you imagine it would work to spray Krylon Fusion Plastic paint into a jar and use it as a brush paint?

Re: Painting ABS Plastic

Or if you want real metal painting/plating go for something like this ---> http://www.riogrande.com/Product/MIDAS- … 070?Pos=22 then electroplate over it with gold, silver, whatever you want ---> http://www.riogrande.com/Product/MIDAS- … 5136?Pos=9 these systems can be home made for a few bucks if you don't want to spend the bucks Riogrande charges.

Re: Painting ABS Plastic

I made this in purple ABS and painted it for my daughters Halloween costume.
Just use Krylon fusion primer and let it dry.

Re: Painting ABS Plastic

Some plastics, like nylon, can be dyed with clothes dye for polyester. It works well on SLS nylon parts and easy to do. Not sure about ABS, but for $4 you can find out. If it doesn't work you can still paint it.

If you paint it, you need to consider what environment and handling the part will experience. Underwater, for example, UV, heat, lot of handling or knocking around.

I've had good luck with the Fusion paint and Testors model paint. Anything designed for plastic should work. When you finish, I suggest you put the part in the sun and wind for a day or two to let it cure thoroughly before using it.
