Our product is an add-on module that can be attached to existing commercial 3D-printer and enables them to print in color. All 3D printers around 1,000 USD can only print objects that have the identical colors as the feeding filaments. However, we are going to change it! With our patent-pending technology, your 3D printers would be able to print objects in any color from natural-color filaments. Our product is perfect for artists, product designers, 3D printer owners, or anyone who is tired of picking the right color of filaments you want.
