Python is one of the prominent programming languages in today’s computing. This research aims to delineate the coding methodology employed to calculate a B-series propeller geometry data. First, geometry data is calculated and stored in an excel sheet. Subsequently, 2D section data of propeller blade is produced. Finally, the 2D data is converted into 3D co-ordinates in global X, Y, Z system. Such a program enables the user to compute, analyze, change and visualize the 3D section view of a propeller. In the realm of contemporary manufacturing techniques, additive
manufacturing emerges as a highly prospective method. This paper aims to provide a structured method of the additive manufacturing process for a marine propeller. The propeller data produced from 'PropCad 2010' serves as the source data for creating 3D surfaces in 'SolidWorks 2017'. 'Ultimaker Cura 5.4.0' is thereupon utilized to generate G-code, which can be used to 3D print an entire propeller. The plausibility of the procedure was put to test through 3D printing a scaled plastic propeller. This paper ventures to present an introductory, step-by-step guide for manufacturing a marine propeller using this novel approach.
