“…The literature also presents results for additively manufactured components for optical fibers [9], scanning devices [10], and laser systems [11], which were produced with commercially available AM systems. The AM of transmissive optical components has been demonstrated using a number of processes.…”

“…At the present stage, AM is entering markets in many diverse industrial fields, including lightweight engineering, energy, medicine and food production (Ligon et al, 2017). Plastic AM is commercially being used for medical implants (Zarek et al, 2016), prosthesis and tissue printing (Liaw and Guvendiren, 2017;Yang et al, 2019), optical products (Kranert et al, 2020), custom machine parts (Yuan et al, 2019), sports equipment (Meier et al, 2019), wearables (Di Nicolantonio et al, 2019) and robotics (Zhu et al, 2020) to name a few. Smart materials such as shape memory alloys (SMAs) and shape memory polymers (SMPs) are materials that can store a temporary shape and return to their original/permanent shape upon the application of a stimulus (Lendlein and Kelch, 2002).…”

Purpose A review on additive manufacturing (AM) of shape memory polymer composites (SMPCs) is put forward to highlight the progress made up to date, conduct a critical review and show the limitations and possible improvements in the different research areas within the different AM techniques. The purpose of this study is to identify academic and industrial opportunities. Design/methodology/approach This paper introduces the reader to three-dimensional (3 D) and four-dimensional printing of shape memory polymers (SMPs). Specifically, this review centres on manufacturing technologies based on material extrusion, photopolymerization, powder-based and lamination manufacturing processes. AM of SMPC was classified according to the nature of the filler material: particle dispersed, i.e. carbon, metallic and ceramic and long fibre reinforced materials, i.e. carbon fibres. This paper makes a distinction for multi-material printing with SMPs, as multi-functionality and exciting applications can be proposed through this method. Manufacturing strategies and technologies for SMPC are addressed in this review and opportunities in the research are highlighted. Findings This paper denotes the existing limitations in the current AM technologies and proposes several directions that will contribute to better use and improvements in the production of additive manufactured SMPC. With advances in AM technologies, gradient changes in material properties can open diverse applications of SMPC. Because of multi-material printing, co-manufacturing sensors to 3D printed smart structures can bring this technology a step closer to obtain full control of the shape memory effect and its characteristics. This paper discusses the novel developments in device and functional part design using SMPC, which should be aided with simple first stage design models followed by complex simulations for iterative and optimized design. A change in paradigm for designing complex structures is still to be made from engineers to exploit the full potential of additive manufactured SMPC structures. Originality/value Advances in AM have opened the gateway to the potential design and fabrication of functional parts with SMPs and their composites. There have been many publications and reviews conducted in this area; yet, many mainly focus on SMPs and reserve a small section to SMPC. This paper presents a comprehensive review directed solely on the AM of SMPC while highlighting the research opportunities.
