Do you do post-processing?

The completed builds only undergo sandblasting to remove surplus polymer. Optionally, they can also be colored.

We use two coloring methods:

1. Dyeing. The application of color by immersing the item into a reservoir of dye. 
2. Graphite blasting. Similar to sandblasting, but with glass and graphite as an abrasive material. It gives the item a dark-gray color.

Dyeing and blasting are inexpensive and efficient ways of getting a high-quality finish.
Available colors: graphite, black, and gray. Other finishes will soon be made available.
