print test 

 
Ricardo Gomes on Vault # Research project 
(...) designed in order to test a new three-dimensional printing technique (...) the material has low tensile strength and a compression only vault structure was preferred (...) size 1 x 1 x 2 metres (...) A sequence of models were produced in order to develop the form (...) a squircle (a special case of superellipse) was eventually chosen as the underlying principal for the vault (...) a degree of diversity in the pattern was necessary (to analyse both the form-finding as well as the printing process), three different arches were introduced (...) The final result could be described as a quasi threefold rotational symmetry.
