Isis Tripod

This tripod is one of the objects being produced in 3D from Piranesi's designs.

A preview of the rotating 3D model corresponding to the tripod

Comparison of the 3D model and a first prototype

The 3D virtual version of one of Piranesi's etchings is shown here as a STL file (left) and produced by voxelstudios in Madrid, after which it has been prototyped by Materialise (right) based in Belgium . The process used to build this prototype from a STL file is called sterolithography, the tripod was divided into sections and then each part is built slice by slice from bottom to top, in a vessel of liquid polymer that hardens when struck by a laser beam. The prototype surface is then reworked by hand in order to add the more intricate details and after which a silicon mould is made from which the tripod shall be cast subsequently.

Blow torching the bronze creates chemical reaction which adds a patina to the surface.

Candelabrum

Fireplace

This is a screen shot of the 3D fireplace being modeled at voxelstudios in a programme called Zbrush, here it is being compared to the original Piranesi etching.

3D scanning of sculpted clay which shall form the decorative freeze around the fireplace

Face models applied to relief details.

 

 

This screen shot of the fireplace was done by Materialise, Belgium, before being rapid prototyped. The cuts indicate where the fireplace was divided into sections to fit the prototype tank.

A short animation of the virtual modelling of the fireplace designed by Piranesi. The video is a result of voxelstudios organic modelling work

The resin prototype prepared by Materialise.

Altar

Original etching of Piranesi's altar

The basin part of the Piranesi altar, modelled in a programme called Zbrush at voxelstudios

The finished altar will be made out of a combination of bronze and marble

Different parts of the altar being assembled in prototype materials.
