The surface of your 3D printed model is defined by the material and technology. In addition, the number of post-finishing also determines the cost and quality of your paintable resin model.
The natural surface of your paintable resin model is what we call ‘basic finish’. That means you get to see and feel the basic material your model was built from. However, resin based models will always be smoother than powder based models. The technology (stereolithography) used for your paintable resin model requires extra material to support your model during the printing process, but these supports are removed before your model is cured (hardened under UV light).
With basic finish, some building layers will still be visible. The natural surface option is always the cheapest option.
Paint it yourself
Although we offer a spray painting option for paintable resin, you can always paint/finish it yourself. Just take a look at the chroming job designer Josh Azevado did on his wedding cake topper.
When the natural color of paintable resin doesn’t meet your needs, we can paint your model with a can of spray paint. You could also do this at home yourself if you prefer.
You can also have your model painted in a professional spraying booth. There are 4 types of paint: dead matt, matt, satin, and high gloss. The difference lies in the gloss factor. In other words, how "shiny" your model looks when it’s painted. The higher the gloss factor, the more light will be reflected from the model. The bigger the surface is on which the paint is sprayed, the bigger the visual difference between the different paint options.
As an example we have painted 4 metal plates in the 4 types of paint and placed a small polyamide ball on top of it. The more the ball is reflected, the higher the gloss factor.
