Previously published evidence has established major clinical benefits from using computer-aided design, computer-aided manufacturing, and additive manufacturing to produce patient-specific devices. These include cutting guides, drilling guides, positioning guides, and implants. However, custom devices produced using these methods are still not in routine use, particularly by the UK National Health Service. Oft-cited reasons for this slow uptake include the following: a higher up-front cost than conventionally fabricated devices, material-choice uncertainty, and a lack of long-term follow-up due to their relatively recent introduction. This article identifies a further gap in current knowledge – that of design rules, or key specification considerations for complex computer-aided design/computer-aided manufacturing/additive manufacturing devices. This research begins to address the gap by combining a detailed review of the literature with first-hand experience of interdisciplinary collaboration on five craniofacial patient case studies. In each patient case, bony lesions in the orbito-temporal region were segmented, excised, and reconstructed in the virtual environment. Three cases translated these digital plans into theatre via polymer surgical guides. Four cases utilised additive manufacturing to fabricate titanium implants. One implant was machined from polyether ether ketone. From the literature, articles with relevant abstracts were analysed to extract design considerations. In all, 19 frequently recurring design considerations were extracted from previous publications. Nine new design considerations were extracted from the case studies – on the basis of subjective clinical evaluation. These were synthesised to produce a design considerations framework to assist clinicians with prescribing and design engineers with modelling. Promising avenues for further research are proposed.

consistentes e cada vez mais presentes nos campos de design e construção. A presença cada vez mais significativa dos sistemas de representação e fabricação com auxílio de computador (Computer Aided Design e Computer Aided Manufacturing) na concepção dos mais variados artefatos, tem sido um assunto muito discutido nos diversos campos da indústria criativa. Paralelamente à esta discussão, a introdução da abordagem projetual paramétrica tem uma grande importância na obtenção de novas perspectivas e inovação no design. Dessa forma, com o intuito de associar o potencial das ferramentas de prototipagem rápida e fabricação digital e de um sistema generativo de projeto, este artigo descreve o desenvolvimento de um projeto de mobiliário – um painel para exposição de objetos e organizador de ferramentas - através da documentação detalhada dos processos e procedimentos realizados para sua conclusão e desdobramentos acerca da mudança de paradigma no processo de projeto, condizente com a potencialidade dos recursos digitais. O texto do resumo deve ser escrito em Cambria tamanho 10, justificado, espaçamento simples, antes 0, depois 0. Deve possuir no máximo 200 palavras. O texto deve ser escrito em um único parágrafo e conter as informações principais do artigo como objetivos, resultados, métodos, etc.
