“…Nesta mesma vertente de desenvolvimento de réplicas tridimensionais, porém naquele momento utilizando o princípio de sobreposição de camadas, embora antiquado para os padrões atuais, em abril de 1890 e patenteado em maio de 1892, Joseph E. Blanther concebeu uma aplicação layer-by-layer para a elaboração de mapas topográficos em alto relevo (Bechthold et al, 2015;Cunningham et al, 2015).…”

“…Na literatura atual os autores muitas vezes consideram que os dois termos se tratam de palavras intercambiáveis ou substituíveis entre si, uma vez que, na sua essência, não há diferença significativa nos princípios associados à tecnologia envolvida (Cotteleer, 2014;Cunningham et al, 2015). Para efeitos do presente estudo, o termo "manufatura aditiva" será empregado genericamente para as tecnologias em questão.…”

The contemporary military sector needs a tailor-made product at a low cost and time. Fused Deposition Modeling (FDM) is a melt extrusion-based Additive Manufacturing technology for processing thermoplastics, composites, and biomaterials. FDM is competent in fabricating complex parts in different industries, including military, aerospace, automotive, biomedical, and jewellery. The FDM can process various materials and is ideal for fabrication prototypes, functional parts, visualization, concept proofs and fast product development. FDM is currently used in the military for novel components developments and maintenance, opening new logistics and supply chain management methods. Integrating sensors into weaponry for real-time physiological feedback and threat information is also possible. Additionally, FDM can fabricate trauma models for surgical planning and educating military surgeons. This paper presents the FDM background, filaments, and process parameters. Also, the work provides information to readers on the applications and possibilities of the FDM process from a military standpoint.

In this work, two AM technologies were utilized to compare the effectiveness of fabricating a simple electronic device with a conductive trace and hollow cylinder representative of 'printed packaging' that would survive harsh environmental conditions. The printed packaging cylinder delineates printed potting for electronics packaging. An nScrypt direct write (DW) system was the primary manufacturing system but a developing technology-coined large area projection sintering (LAPS)-manufactured a subset of samples for comparison. The tests follow Military Standard (MIL STD) 883 K and include resiliency evaluation for die shear strength, temperature cycling, thermal shock, and high G loading by mechanical shock. Results indicate DW Master Bond epoxy devices show resilience to extreme temperatures, thermal shock, and mechanical shocks while also surpassing the die shear strength failure criteria specified by the MIL STD. LAPS sintered Nylon devices also show mechanical resilience to thermal shock and surpass the die shear strength failure criteria. However, there were some open circuits, increases in resistance, and delamination when LAPS Nylon devices were subjected to extreme temperatures and 20 000 G shock loading normal to the substrate. The thermal effects are likely due to the thermal expansion mismatch between Nylon and the conductive paste while the mechanical shock effects may be attributed to the geometry differences of the LAPS Nylon printed packaging. Further studies are required to understand these failure modes in some of the LAPS Nylon samples and refine the process to address them.
