Instead of using paper, the 3D printing process consists of applying very thin layers of a powder/plastic compound to gradually form the complex shapes of a design.
Firstly, a 3D model of the proposal is produced following a rigorous procedure to avoid any open edges and corners; the model is hollowed where possible to save on cost of materials and ‘printing’ time. A file fixing software is then used to analyse the geometry and check for any modelling imperfections that could potentially cause a problem during the printing process.
The digital 3D Model is then sent out to a specialised printing facility to be physically printed. Finally, the 3D Print undergoes a cleaning process and is populated, if required with trees, cars etc.
