“…3D printing of highly pure copper with superior electrical and thermal properties has been studied extensively due to its broad potential in many applications including electronic devices [1,[12][13][14][15][16][17][18][19][20], thermal management systems [4,12], and the aerospace industry [4,12,[21][22][23][24][25]. Compared to conventional 3D printing of highly pure copper with superior electrical and thermal properties has been studied extensively due to its broad potential in many applications including electronic devices [1,[12][13][14][15][16][17][18][19][20], thermal management systems [4,12], and the aerospace industry [4,12,[21][22][23][24][25]. Compared to conventional fabrication methods such as metal casting, welding, and machining, 3D printing can fabricate more optimized and complex 3D copper parts without using additional tools [26][27][28][29][30][31]…”

Copper has been widely used in many applications due to its outstanding properties such as malleability, high corrosion resistance, and excellent electrical and thermal conductivities. While 3D printing can offer many advantages from layer-by-layer fabrication, the 3D printing of highly pure copper is still challenging due to the thermal issues caused by copper’s high conductivity. This paper presents a comprehensive review of recent work on 3D printing technology of highly pure copper over the past few years. The advantages and current issues of 3D printing methods are compared while different properties of copper parts printed by these methods are summarized. Finally, we provide several potential applications of the 3D printed copper parts and an overview of current developments that could lead to new improvements in this advanced manufacturing field.

“…The authors further prepared concave and convex square structures of Cu NPs of various dimensions using the same method and sliding conditions (Figure 3c). 78 Under different loads and relative speeds, the convex square structure had a better friction-reducing ability than the concave one (Figure 3d). Thus, the importance of structural morphology in the lubrication of mechanical systems was highlighted by identifying the optimal structural size parameters of the convex square texture as 400 μm × 400 μm in length and 300 μm in spacing.…”

The rapid development of three-dimensional (3D) printing technology opens great opportunities for the design of various multiscale lubrication structures. 3D printing allows high customization of arbitrary complex structures and rapid prototyping of objects, which provides an avenue to achieve effective lubrication. Current experimental observations on superlubricity are limited to atomically smooth clean surfaces, extreme operating conditions, and nano-or microscales. With the in-depth exploration of 3D printed lubrication, construction of multifunctional 3D structures with refined dimensions spanning from micronanoscale to macroscale is increasingly regarded as an important means to approach superlubricity and has aroused great scientific interest. To document recent advances in 3D printing for structural lubrication, a detailed literature review is provided. Emphasis is given on the design and lubrication performance of geometric and bioinspired lubrication structures with characteristic dimensions. The material requirements, merits, drawbacks, and representative applications of various 3D printing techniques are summarized. Potential future research trends aiming at the design strategy and manufacturing process of 3D printed lubrication structures are also highlighted.

“…Additive texturing is a state-of-the-art approach for fabricating surfaces with superior tribological, wetting, and wear characteristics [ 148 ]. In [ 149 ], Wang et al used the selective laser melting of ink-printed copper nanoparticles (SLM-IP Cu NPs) in order to fabricate a friction-reduced surface for operating in mixed-lubrication conditions ( Figure 5 A). The patterns investigated were concave and convex, squared and fully sintered Cu film; the height of the features was 20 μm.…”

Design Aspects of Additive Manufacturing at Microscale: A Review

et al. 2022

View full text Add to dashboard Cite

Additive manufacturing (AM) technology has been researched and developed for almost three decades. Microscale AM is one of the fastest-growing fields of research within the AM area. Considerable progress has been made in the development and commercialization of new and innovative microscale AM processes, as well as several practical applications in a variety of fields. However, there are still significant challenges that exist in terms of design, available materials, processes, and the ability to fabricate true three-dimensional structures and systems at a microscale. For instance, microscale AM fabrication technologies are associated with certain limitations and constraints due to the scale aspect, which may require the establishment and use of specialized design methodologies in order to overcome them. The aim of this paper is to review the main processes, materials, and applications of the current microscale AM technology, to present future research needs for this technology, and to discuss the need for the introduction of a design methodology. Thus, one of the primary concerns of the current paper is to present the design aspects describing the comparative advantages and AM limitations at the microscale, as well as the selection of processes and materials.
