Material Optimization, Reverse Engineering and Rapid Prototyping of a Handmade Shaver

Abstract

This study investigates the optimization of materials for a hand-crafted razor using innovative additive manufacturing techniques. It reviews previous patent designs to avoid replicating existing ones. Subsequently, a preliminary razor drawing was created based on hand biomechanics to determine compatible hand grips. This process culminated in a functional prototype, digitally rendered using a FARO Edge E09-05-17-32364 scanner supported by point cloud data. Various ComputerAided Design (CAD) software’s were utilized to generate a digital model saved in an STL file format. Employing Fused Deposition Modeling (FDM) with ABS and PLA, alongside Stereo-lithography/Digital Light Processing (SLA/DLP) with resin technologies, the final prototype was produced, achieving a 45% material optimization in the handle. Additionally, gripping system for the razor blade was designed at the shaver’s tip, ensuring secure closure a satisfactory performance.
