INTEGRATION OF ARTIFICIAL INTELLIGENCE, 3D PRINTING AND INTELLIGENT AUTOMATION IN PROSTHETIC LIMB DEVELOPMENT

Abstract

Artificial limbs are specially developed medical and engineering devices that help individuals overcome functional limitations resulting from limb loss or congenital limb conditions. The development of these devices involves much more than the fabrication and joining of mechanical components. Engineers must consider several aspects, including the user's physical requirements, the condition of the remaining limb, comfort, structural strength, material properties, component selection and ease of operation. The prosthesis should also provide dependable performance during everyday activities while remaining convenient to maintain and adjust. Recent developments in artificial intelligence (AI), digital design and automated manufacturing are creating new opportunities to improve the way prosthetic devices are designed, fabricated and assembled. These technologies can support customised product development, improve manufacturing accuracy, assist movement control and help identify possible component failures. This paper explores the application of modern engineering technologies in the development and assembly of upper- and lower-limb prosthetic devices. It discusses the construction and functions of major prosthetic components, suitable engineering materials, computer-aided design (CAD), additive manufacturing and the integration of mechanical and electronic systems. Particular attention is given to the use of AI and intelligent automation in prosthetic development. Applications such as digital image processing, finite element analysis (FEA), intelligent material selection, interpretation of muscle-generated electrical signals, robotic assembly and digital manufacturing records are considered as important tools for improving design and production processes. The integration of advanced manufacturing methods with AI-based engineering tools has the potential to make prosthetic development more personalised, efficient and accessible. However, the ultimate objective should remain the creation of devices that address real user requirements and deliver dependable performance. A systematic approach combining sound mechanical design, controlled manufacturing, proper assembly, experimental verification and professional fitting can help transform emerging engineering technologies into practical prosthetic solutions.
