A paradigm shift...
Sculpman's patented Variable Nozzle Technology is an innovative approach to speed up and improve plastic extrusion 3D printing without having to compromise on feature detail or visual quality. The most fundamental idea was to break away from circular nozzle shape thinking which has been the de-facto standard for decades.
If you come to think about it, a circular output shape, which produces cylindrical 'spaghetti' tracks is not really an optimal configuration for effeciently printing clean layers. Cylindrical tracks that are placed horizontally next to each other (e.g. to make a perimeter that is 2 walls wide) produce a wave pattern. Even if they are squished slightly flat by the nozzle (e.g when extruding more than the layer height dictates) the area with which both tracks touch is still small, as each track's cross-section is elliptic and only the mid section of the sides touch.
In contrast, the Sculpman nozzles deposits ribbons of varying width that can draw a coherent, flat track that is multiple millimiters wide in a single stroke.
