A 3D printer was built, capable of spray depositing silicone on to double curved (rotating) mandrels
Silicone being cured by infra-red. Spray head visible in backgroundConstant layer thickness DEA layers. The last (upper) two layers are double thickness.Various thickness layers produced during spray deposition tests. Variation in thickness due to changing spray paramenters for testing purpose. Minimum (consistent) layer thickness was 40um
