Color Resist is a dyeing finish achieved with the DyeMansion technology and most specifically with the DM 60 dyeing machine. This finish gives your 3D printed parts a matte look that resists friction. Thanks to the post-printing treatment procedure we follow before applying the Color Resist finish on your 3D parts, they get resistant enough to be exposed to external conditions and they resist scratching and rubbing. Moreover, you get a very stable and consistent color between different production batches, which is great if you need to produce an important amount of identical parts. The surface shows a uniform color, with a very good quality.
If your 3D printed white Nylon PA12 parts are meant to be exposed to external conditions for an extensive period of time, we recommend you to dye them with this finish so as to avoid the unwanted “yellowing” color alteration. Thanks to the Color Resist finish, your 3D printed parts become high quality finished products, with great longevity.
Parts that are colored with DyeMansion technology are skin-safe. In addition, the dye stuff and the additives allow us to achieve a high UV-resistance. Some of our customers’ colored products like 3D printed glasses have been used daily for more than two years and their colors are still UV-stable and brilliant. Thus, the Color Resist finish is a great choice if your part will often be exposed to UV light, and you want the color to remain stable over time.
Submerged in a water bath, the dye penetrates the plastic through a chemical reaction under pressure and heat. The penetration depth is typically 0.2 mm and can even be increased using our intensive color solution. No material is added and every surface is reached in the water bath.
Dyeing with Color Resist finish can extend the processing time by 1-3 days on average, which means:
Express production: unavailable.
Standard production: minimum 5 to 7 days on average.
Economy production: unavailable.
The maximum size for dyeing your models with the Color Resist finish is limited by the physical size of the dyeing tank of the DM 60 machine. Your designs must respect this maximum size in order to be dyed with Color Resist finish. There is no minimum size for dyeing with Color Resist finish.

The DyeMansion coloring solution is compatible with parts of every geometry. Even very filigrane or complex parts get through the coloring process without any problems. Submerged in a water bath, the dyestuff penetrates the plastic through a chemical reaction under pressure and heat. In this way the dye reaches spots that cannot be colored homogeneously with painting. Due to the chemical reaction that occurs between dye and material, the parts retain their geometric properties.
We advise you though, to avoid hollowing your 3D printed parts, as they might float inside the tank and not be colored homogeneously. In addition, engraved parts with small depth of carving are likely to get filled with ceramic powder during the procedure of sandblasting that the parts go through. If an engraving is an essential part of your design we recommend making them as deep as possible so that they will be able to be cleaned out. To ensure a better powder removal (thus a better detail visibility), the width of your details must be at least as big as deep.
Please be aware that engraved lines from 0.3 to 0.6mm could have cleaning media stuck in the cavities.
