The use of the Etalon as a measurement instrument is wide spread, but this additives printer uses etalons to not only measure with absolute precision the structure being printed but it also aids in creating the environment for the infrasonic sound to travel through the fiber optic cables and out with the laser into the induction environment where it penetrates the additive metals deep enough with absolute precision to increase temperatures and combine the additives into metal objects.

There is a lot more to this process but in essence the more fiber optic infrasonic lasers there are the faster these objects will be printed.

The shape of the printer will be cylindrical, the fiber optics will be layered surrounding the 3d printable grid environment and will be adjusted using light and sound or as tesla would put it by using energy, frequency & vibration
