A variety of methods and tools for product design have been developed and introduced in recent years within high-tech enterprises to improve their competitiveness. The positive consequences of their use are indisputable: without them, it would not be possible to shorten development cycles, reduce costs and improve product quality and reliability. Deploying Technical Functional Analysis (TFA) techniques in the field of additive manufacturing (AM) brings the following significant benefits: lower costs; reduction in material consumption; reduction in manufacturing time; shorter time-to-market; improving the accuracy of certain operations; improving the efficiency of studied processes and procedures. The design of a product determines: functions; choice of materials;
dimensions; design; performance; assembly conditions; tolerances etc. Consequently, quality and cost (future costs) are attributable to 70-75% following the end of the design phase. The application of TFA, along with methods that involve a better understanding of the design process, favours taking the best decisions in the early stages, thus reducing the final costs. This paper shows that using TFA in the development process for AM-enabled bespoke products, ensures that the best decisions on product and process concepts have been made from these early stages.
