Integrated Practical Framework for Multidisciplinary Prototype Design and Manufacturing Process

This article highlights the multidisciplinary approach of additive manufacturing employing ergonomics and reverse engineering in prototyping for practical applications. Based on a practical example, a personalized prototype was developed with reduced overall weight, improved air circulation, and an ergonomic design. Virtual testing demonstrated a suitable level of overall comfort, with a "Comfort" index score of 30.3, a "Back" assessment score of 6.5, and a "Rump" assessment score of 30.1. The use of digital ergonomic testing also helped eliminate costs and reduce the time required for prototype development. The final prototype was produced using Multi Jet Fusion technology. The entire process, from prototyping to real production, confirmed the suitability of the developed methodological framework for ergonomic prototyping through the application of reverse engineering. This approach forms the central focus of the article. In conclusion, the overall findings and benefits of the methodology for both science and practice are presented in alignment with the prototyping process.
