Using the Fuzzy-QFD for Product Development: A Case Study for 3D Printer

Abstract

In this paper using Fuzzy-QFD approach to product development: case studyfor 3D printer. The method that translating the customer needs into technical term, Fuzzy-QFDmentioned illustrate that it can be utilized in different ways and can be adapted to solve a greatnumber of design problems. The study starts by determining customer demand. Thereafter, identifying technical requirement based on QFD. This paper integrates fuzzy set theory and house of qualityto determine the importance weight of the customer requirement and the relationship between customer requirement and the technical requirement. The results proposed Fuzzy-QFD approach can be expected to be successful and has potential for multiple criteria decision-making problems.

Use of the QFD method to redesign a new extrusion system for a printing machine for ceramics

“…QFD has been used in industry to design different components: in the automotive industry for car design [26], in the construction industry, for example for processing the customers' requirements [27,28], or in the food industry [29,30], among others.As for additive manufacturing equipment,Da Silva et al used the fuzzy-QFD approach to develop a 3D printer. They found the relationship between the customer demands and the technical requirements [31]. Caligiana et al used QFD to validate the design process of an open mold that will help combine additive and subtractive technologies [32].Efstathiadiset al used QFD to improve the design of a 3D printed surgical instrument [33].…”
