“…Esse é um termoplástico de alto desempenho retardador de chamas para fabricação digital direta e manufatura aditiva de alta relação resistência e peso (Masood, 2014;NASA Tech Briefs, 2015;Sobon, 2018). Também foram identificados estudos com o processo SLM utilizando o material PEEK (Poly(Ether-Ether-Ketone)), um termoplástico semicristalino de alto desempenho (Korn, 2011;Dietz et al, 2018).…”

“…Algumas aplicações do processo FDM na indústria Aeroespacial foram encontradas (R. G. J. Clinton, 2018;Dietz et al, 2018;Gaudenzi et al, 2018;Herderick, 2015;McClain et al, 2019;Nickels, 2015;Schiller, 2015). A crescente disponibilidade de novos materiais como o Ultem 9085 da fabricante SABIC B.V., Holanda e o PEEK, podem aumentar a participação do processo FDM neste mercado nos próximos anos com a evolução dos equipamentos, matérias-primas e com o aumento do conhecimento das propriedades mecânicas, da repetibilidade e dos testes necessários para confirmar a adequação dos itens manufaturados aos requisitos ambientais.…”

Additive Manufacturing (AM) of three-dimensional objects is now being progressively realised with its ad-hoc approach with minimal material wastage (lean manufacturing) being one of its benefit by default. It could also be considered as an evolutional paradigm in the manufacturing industry with its long list of application as of late. Artificial Intelligence is currently finding its usefulness in predictive modelling to provide intelligent, efficient, customisable, high-quality and sustainable-oriented production process. This paper presents a comprehensive survey on commonly used predictive models based on heuristic algorithms and discusses their applications toward making AM “smart”. This paper summarises AM’s current trend, future opportunity, gaps, and requirements together with recommendations for technology and research for inter-industry collaboration, educational training and technology transfer in the AI perspective in-line with the Industry 4.0 developmental process. Moreover, machine learning algorithms are presented for detecting product defects in the cyber-physical system of additive manufacturing. Based on reviews on various applications, printability with multi-indicators, reduction of design complexity threshold, acceleration of prefabrication, real-time control, enhancement of security and defect detection for customised designs are seen of as prospective opportunities for further research.

<div class="section abstract"><div class="htmlview paragraph">Acrylonitrile Butadiene Styrene (ABS) is a highly sought-after engineering plastic for industrial applications, particularly in modern aircrafts. It offers better balance of impact strength, tensile strength, thermal resistance, dimensional stability, processing ability and affordability, the aircraft interior parts are made up of ABS plastic. However, ABS plastic is not a good choice for heavy-duty industrial applications that require corrosion resistance, abrasion resistance and durability. Several studies have been published on surface metallization of ABS plastic using conventional electroplating and electroless methods, but there is little information is available on the use of thermal spray technique. This opens up a huge opportunity for research in this area to be conducted using most commonly used materials like zinc and low carbon steel. In the light of the above, the current work employs an electric arc spray technique to coat zinc and low carbon steel on ABS plastic. Prior to coating the alumina grit blasting was carried on tensile and bending samples which were prepared as per ASTM D638 and ASTM D790 standards respectively. Comparative studies showed that the zinc coated ABS samples showed better tensile strength, flexural strength and flexural modulus than that of low carbon steel coated ABS specimen. Visual examination showed good surface finish with no surface damage for zinc coated ABS component.</div></div>
