Students from the Master of Digital tectonics designed and fabricated their own helix.
The cost of this tool in the market was very high and the customized dimensions did not exist.
The mold was milled in foam with the CNC milling machine,
then sprayed with realise spray or silicone, sealed perfectly
and the final piece was made out of plastic liquid compound resin.
The helix will be placed in a transparent pipe and by rotating it with a servo motor
will control the flow of concrete distributed in the
nozzles of deposition.
