Nylon SLS prints of Le Corbusier's "Ronchamp Chapel" with Multi-Colour base. CAD flie by D2W


When Bart Radecki joined our team, we were keen to get him to produce a definitive 3d printed Architectural model that demonstrates what makes this technology a brilliant tool for this purpose.  Bart is an experienced traditional model maker with exceptional Rhino skills who has worked in the model making departments of several leading London practices.

We chose a famous and geometrically challenging building for this exercise; Le Corbusier’s chapel “Notre Dame du Haut”, more commonly known as Ronchamp and completed in 1954.
 
With all 3d printing, the first step is to obtain or produce a CAD file.  With this building being so complex geometrically, Bart immediately decided to produce the CAD file using a combination of original working drawings from Le Corbusier’s book of the building published upon its completion and then measured and modified them against photographs of the finished building.  This was about a week’s worth of CAD drawing, at the end of which he had a compellingly accurate model of the building.
 
The next stage was to consider how to design the model in terms of any separate pieces that could be used to express and reveal the model in its best detail. It was decided to print the model in just 4 parts.
  • The base was designed for and printed in Multicolour, allowing us to represent the site.
  • The main body of the building itself was designed to be printed in a single Nylon SLS piece.
As the building itself has a white rough rendered finish, we even applied a rough texture to the surface of these walls to replicate the original even more accurately.
 
The roof was then separated from the CAD model and given a slight tolerance around the perimeter to allow it to be lifted off to reveal all of the internal detail.
 
The final piece was the small water trough that catches the rainwater from the spout at the rear of the roof.  The roof and the trough were then both dyed grey in order to replicate their original materials.
 
This is a beautiful example of an exemplary CAD file being designed in separate components, so that when they are all brought together, they produce a spectacular result.
