As for the video itself:
Painting > 3D printing
Dyes > Painting
To achieve Bionicle quality, bionicle pieces MUST be used. 3D-printed parts can never get the same smoothness and quality as real bonkles. If you look closely, even the smoothest 3D-printed piece can be exposed as artificial.
Dyes are superior to paint because it's permanent. Dyes can be scratched off, and thus they are inferior.
All in all, very good technique and doesn't ruin the parts, as opposed to paint which does permanently ruin parts.
