“…1 Rapid prototyping using advanced jet-based routes, which also include filaments, have been investigated but show limitations with regard to structural accuracy and surface finish. [1][2][3] Three such fabricating routes, which have undergone rapid development in the last decade or so are three-dimensional printing [4][5][6] ͑3DP͒, ink-jet printing 7-9 ͑IJP͒, and fused deposition modelling. [10][11][12] There are other routes such as ballistic particle manufacture, [13][14][15] which uses IJP technology, however, IJP and 3DP are the most relevant when comparing the instrument and method pioneered in this work.…”

A print-patterning instrument coupling electrohydrodynamics and servo and stepper motor motion has been developed. It has been used to pattern and form a 10mm×30mm rectangular walled container from zirconia. The incorporation of electrohydrodynamics allows the generation of finer droplets, compared with ink-jet technology, from a concentrated two-phase medium. The precision servo/stepper system consists of a three-axis motion planner, which is computer controlled and allows three cradles to be in motion according to a predetermined sequence created on any computer aided design package. The problems encountered in forming three-dimensional (3D) structures using this method are explained and possible solutions incorporating future work are discussed. This instrument has the potential of being developed into a powerful device for 3D solid freeform fabrication of structural, functional, and biological structures.

“…[210][211][212][213] Conventional technologies, including ion exchange and sol-gel techniques, with common limitations such as long processing times (typically >100 h) and limited component sizes (typically <13 mm), can be overcome by using FGMs and FGSs. [214] Roper et al [210] printed dielectric powders (ECCOSTOCK HiK) on fabric-glass composite substrates (S-glass/cyanate ester fiber reinforced via ultrasonic powder deposition. By printing and stacking multiple layers using single-layered dielectric powder (Figure 17a,b), a final composite with a graded variation of permittivity in the vertical direction was created.…”

Functionally graded materials (FGMs) and functionally graded structures (FGSs) are special types of advanced composites with peculiar features and advantages. This article reviews the design criteria of functionally graded additive manufacturing (FGAM), which is capable of fabricating gradient components with versatile functional properties. Conventional geometrical‐based design concepts have limited potential for FGAM and multi‐scale design concepts (from geometrical patterning to microstructural design) are needed to develop gradient components with specific graded properties at different locations. FGMs and FGSs are of great interest to a larger range of industrial sectors and applications including aerospace, automotive, biomedical implants, optoelectronic devices, energy absorbing structures, geological models, and heat exchangers. This review presents an overview of various fabrication ideas and suggestions for future research in terms of design and creation of FGMs and FGSs, benefiting a wide variety of scientific fields.

“…Em princípio, não há limitação quanto aos materiais que podem ser utilizados neste processo, sendo comum o uso de amido, gesso, polímeros, pós cerâmicos e metálicos [2]. No caso de materiais cerâmicos, esse podem estar presentes tanto no pó quanto no material aglutinante [21][22][23][24][25][26].…”

Tecnologias de Prototipagem Rápida (Rapid Prototyping, RP) permitem a fabricação automática de peças com geometria complicada a partir de dados de Projeto Auxiliado por Computador (Computer Aided Design, CAD). A peça tridimensional é construída por consolidação de pó em camadas (processo "aditivo" ou "generativo"). Por isso, estas técnicas estão freqüentemente chamadas de fabricação de forma livre sólida ou fabricação em camadas. Em geral, uma abordagem de 5 etapas do desenvolvimento de produto é comumente aplicada: criação de um modelo de CAD, conversão do modelo de CAD em formato STL, fatiamento do arquivo STL em camadas de seção transversal, fabricação do produto, e finalmente acabamento superficial do produto. Técnicas de RP têm muitos benefícios sobre métodos tradicionais para geração de modelos, ferramentaria e construção de peças de produção de qualidade. Por exemplo, em contraste com processos "subtrativos" (furação, moagem, desbaste) os métodos "aditivos" de RP permitem a fabricação de produtos com estrutura complexa de poros internos que não podem ser fabricados por outros métodos. Técnicas de RP podem diminuir significativamente o tempo de fabricação de pilhas a combustível de óxido sólido (PaCOS) com pequena despesa de operação e reduzido custo de produto quando aplicadas corretamente. Tecnologias como Sinterização Seletiva a Laser (Selective Laser Sintering, SLS), Manufatura de Objetos Laminados (Laminated Object Manufacturing, LOM) e Impressão 3D (3D Printing, 3DP) podem ser usadas para fabricação de protótipos de pilhas a combustível, em particular na configuração planar.
