How to Paint 3D Printed Nylon

Nylon turns out to be great for paint and varnish because it is a highly polar polymer. Unsurprisingly, paints specifically for plastics usually end up working the best for 3D printed parts. Usually Rust-Oleum or Krylon have a wide variety (in color and application) of paints that work on 3D printed plastics.

Can you paint 3D printed plastic?

Paints can fall into various categories based on their solvent. The most common ones are oils, enamels, lacquers, and acrylics, most of which will work well with both ABS and PLA. As a newbie, you’d be wise to stick to acrylic paints since they dry fast and can be cleaned with water.

How do you dye nylon 3D prints?

Therefore, when nylon absorbs water with a water-soluble dye, it absorbs the water and dye and ends up permanently colored. By heating up some water and adding dye, the dye can easily diffuse into the water, and the combination, when heated, can more easily dissolve into the 3D printed nylon.

Can you paint nylon?
