ENGINEERING, AEROSPACE, Frequency Selective Surface, Filter, Free-space measurement, and Measurement and prototyping
The design, prototyping, and free-space measurement of a 6-GHz Frequency Selective Surface filter is presented. The prototyping resolution of a large (A4 sheet size) Frequency Selective Surface with small loops as elements is checked, as well as the correlation with measurements performed with a 3-D full-wave solver. The test also involved the effect of cascading two different Frequency Selective Surfaces with a viewpoint towards a narrower frequency range, which provided good results.

ENGINEERING, BIOMEDICAL, Developmental dysplasia of the hip, Orthosis, and Rapid prototyping
Introduction Immobilization in a hip spica cast is required in surgical and nonsurgical treatments for children aged three months to four years diagnosed with developmental dysplasia of the hip. Skin complications are associated with the use of the spica cast in 30% of the cases. This research explores the use of photogrammetry and rapid prototyping for the production of a lighter, shower friendly and hygienic hip orthosis that could replace the hip spica cast. Methods Digitalized data of a plastic dool was used for design and fabrication of a customised hip orthosis following four steps: 1) Digitalization of the external anatomical structure by photogrammetry using a smartphone and open source software; 2) Idealization and 3D modeling of the hip orthosis; 3) Rapid prototyping of a low cost orthosis in polymer polylact acid; 4) Evaluation tests. Results Photogrammetry provided a good 3D reconstruction of the dool's hip and legs. The manufacture method to produce the hip orthosis was accurate in fitting the hip orthosis to the contours of the doll. The orthosis could be easily placed on the doll ensuring mechanical strength to immobilize the region of the hip. Conclusion A new approach and the feasibility of both techniques for hip orthosis fabrication were described. It represents an exciting advance for the development of hip orthosis that could be used in orthopedics. To test the effectiveness of this orthosis for developmental dysplasia of the hip treatment in newborns, material and mechanical tests, design optimization and physical tests with patients should be carried.

3D printing -- Methods and Evolution -- Methods
Keywords Branching path; Trajectory; Innovation pathways; Paradigm; Industry scenario; Meso-level Highlights * New technology fields can be represented as paths that build momentum, fork and evolve. * Forecasting Innovation Pathways (FIP) require a further developed theory of path emergence and evolution. * 3D printing can be represented by a dominant design: a tri-partite configuration that is filled in a variety of ways. * 3D printing is a field which evolved first around prototyping applications and has branched out to new applications. * The interplay of foreseen applications and the filling of the tri-partite schema motivate branching from rapid prototyping. Abstract In recent years, the Forecasting Innovation Pathway approach (FIP) has shown to be a promising set of tools to capture potential developments in emerging fields through capturing indications of endogenous futures. However, the FIP approach is reliant on a clear demarcated area to study, a challenge for emerging technology fields where uncertainty and rhetoric abound. This paper presents an addition to the FIP toolbox that helps characterise and demarcate boundaries of emerging fields to allow for deeper analysis through other FIP methods. We illustrate this approach through an exercise for 3D printing technology (also known as Additive Manufacturing). We show that 3D printing can be represented by a dominant design: a tri-partite configuration of printer, material and digital design software. In the past decade we have seen significant branching from applications in rapid-prototyping to medical, fashion, aeronautics and supply chain management with a variety of elements coming together in tri-partite configurations. The paper adds to the current FTA literature an approach building on evolutionary theories of technical change to help with such situations -- emerging, evolving and branching 'innovation pathways'. Moreover, we developed a methodology to construct these innovation paths.

A tecnologia de prototipagem de produtos por adição de material (Rapid Prototyping) e por remoção de material (Subtractive Rapid Prototyping) pode variar em: qualidade, tempo e custos, dependendo das características do produto. A escolha da tecnologia muitas vezes está condicionada à decisão empírica do designer/engenheiro ou operador, devido ao tipo de material, dimensão e precisão. Este artigo apresenta um método para tomada de decisão que auxilia a escolha da tecnologia de prototipagem rápida mais adequada na concepção de novos produtos. Foram utilizados os conceitos de DFM (Design for Manufacturing), CAD (Computer Aided Design), RPD (Rapid Product Development) e MAUT (Multiattribute Utility) em dois produtos de diferente estrutura e material (composto leve e simples maciço) para avaliar e validar o método proposto. Os resultados apresentam comparações entre as tecnologias de prototipagem rápida a partir de critérios para tomada de decisão, aperfeiçoando a concepção de protótipos mais eficientes. The prototyping of products by additive material (Rapid Prototyping) and by subtractive material (Subtractive Rapid Prototyping) technology can vary in: quality, time and costs, depending on the product characteristics. The selection of technology often is conditioned to the designer/engineer or operator empirical decision due to the type of material, size and accuracy. This paper presents a method for decision making to assist the best choice of rapid prototyping technology on new product conception. We used the concepts of design for manufacturing (DFM), rapid product development (RPD) and computer aided design (CAD) for two products of different structure and material (lightweight dual and simple solid) to evaluate and validate the proposed method. The results show comparisons between the rapid prototyping technologies based on decision making, improving the conception of most efficient prototype.
