Evaluation of Orthosis Rapid Prototyping During the Design Process: Analysis of Verification Models

Abstract

Accessing physical prototypes is possible to test an idea quickly with models that look like the final product. Rapid Prototyping (RP) based on additive or subtractive technology permit to conduct trial tests of usability in order to avoid errors and failures before the final product production. Those technologies are increasingly in orthosis's production. Ergonomics field involved in the design process with RP can facilitate usability tests providing comfort, safety, and performance in the development of orthoses. The objective of this study is to review, accessing the specialized literature, the use of RP for prototypes' production for user's evaluation of orthoses. The results showed that the most common technique used was FDM. Half of the studies involved user's participation or evaluation in the design processes, although, only three out of thirty-eight studies used RP to proof of concept's production, indicating little use of proof-of-concepts models.

Experiences Using Three App Prototyping Tools with Different Levels of Fidelity from a Product Design Student’s Perspective

“…This study explored three prototyping tools with different levels of fidelity [5], namely Adobe XD, Figma and React Native. The experiences with the tool is documented with a product design student who is well trained in design-thinking and prototyping of physical objects using rapid prototyping and 3D printing [6,7,8,9], and basic experience with software development and interface prototyping.…”
