Possibilities for producing the coloured surface of the vault in the Hippolytuskerk

On the 24th of April, 2017 proposals were made for the surface of the 3D printed structure:

1.  To add a thin 3D printed layer with microstructures, and final colours (maximum curvature/thickness of 5 cm) – which is added on a flat surface of a solid 3D  structure, to reduce the costs.
2. Alternatively, the thin 3D printed surface, can be added to a spider-like structure, instead of a solid structure. This kind of structure could in future also be used in architectural heritage to fill e.g. holes, or missing parts as an alternative to Styrofoam, as illustrated in the image below.
3. To print a coloured 3D model. However, the colour will have a plastic looking nature, as the technology does not provide an inkjet quality yet.
4. To print the final colors and textures on a thin foil layer (50 microns) and fix it over the solid 3D structure, which in this case will have all the microstructures, and grains. The foil should be flexible and soft enough to stretch over the 3D structure.
