After creating 3D models of their religiously meaningful objects, project teams 3D printed their objects. Most teams used an Ultimaker 3 printer. A few students used the da Vinci Color 3D printer. 3D printing, also known as additive manufacturing, builds a 3D object by slowly adding layer after layer from the build plate up. Many of the objects created for this class took over 24 hours to print. As the photographs and videos below show, the 3D printer simultaneously fashions the actual object and all necessary support structure. Support material on the Ultimaker 3 is water soluble and only needs to be soaked overnight to be removed, leaving behind the finished model.
