Scanning is a process that has been known to us for many years. Initially, scanning was done only in two dimensions, and this was called copying some content in that way. Later on, the scanned content was also digitized, which allowed the data to be processed, edited, and enhanced. As computer technology advanced, it opened the door to digital three-dimensional scanning, which is currently the pinnacle of technology. This enables almost all types of three-dimensional objects to be scanned, creating their computer representation, discovering defects, and finding the best way to eliminate them. According to a technical definition, 3D scanning is the process of analyzing a three-dimensional object with the intention of collecting data that precisely defines geometry.
A 3D scanner, in combination with computer software, now immediately shows all the irregularities, inequalities, and unevenness of the propeller blade. It allows for determining the thickness of the propeller blade and calculating its volume, based on which the mass of each propeller blade can be calculated. This is a very important piece of information that determines whether the propeller is well balanced since the difference in mass between individual blades is the biggest cause of vibrations. Data obtained from 3D scanning enables a thorough analysis of the propeller, and then based on this data, it can be optimized to raise its class to the desired level.
As for the question of whether to optimize the propeller and whether it is worthwhile, the best answer can only be given by the owner. Those who sail a lot will find a positive answer through significant fuel savings on an annual level.
