“…Faced with the production of some parts with higher surface quality requirements, it is difficult for the formed parts to directly reach the use standard, so special methods are needed to treat the surface of the parts [71,115]. In the study by Karakut et al [116], a method called magnetically driven abrasive polishing technique was developed. This method can be used to polish the surface of complex parts.…”

With the development of the aerospace and automotive industries, high heat exchange efficiency is a challenge facing the development of various industries. Pure copper has excellent mechanical and physical properties, especially high thermal conductivity and electrical conductivity. These excellent properties make pure copper the material of choice for the manufacture of heat exchangers and other electrical components. However, the traditional processing method is difficult to achieve the production of pure copper complex parts, so the production of pure copper parts through additive manufacturing has become a problem that must be overcome in industrial development. In this article, we not only reviewed the current status of research on the structural design and preparation of complex pure copper parts by researchers using selective laser melting (SLM), selective electron beam melting (SEBM) and binder jetting (BJ) in recent years, but also reviewed the forming, physical properties and mechanical aspects of pure copper parts prepared by different additive manufacturing methods. Finally, the development trend of additive manufacturing of pure copper parts is also prospected.

“…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][32][33][34]. Postprocessing methods such as abrasive polishing [35] and hot isostatic pressing (HIP) [36][37][38][39] could enhance physical properties of the printed copper parts further. However, 3D printing of pure copper has several significant processing challenges that need to be addressed.…”

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.

“…These techniques provide a decrease of the roughness of the laser deposited part surface and eliminate the satellite defects (such as protrusions), various edge defects (such as unsuitable levels of edges and their shape), and the morphological defects (such as waviness, blobs, and zits) [31]. Particularly for the Cu-based system, a magnetically driven abrasive polishing was implemented by I. Karakurt et al [88] to improve the quality of electron beam melting-fabricated copper samples. The results showed a decrease in surface roughness from 35 μmto4μm.…”

Direct energy deposition is a reliable additive manufacturing method of producing components with highly sophisticated geometry from a single material or combination of different materials with high manufacturing freedom and efficiency. The assembly operations are not required after the direct energy deposition: such complex parts as a rocket combustion chamber, a nuclear reactor element, a heat exchanger, and so on, could be fabricated layer-by-layer during one technological step. Promising applications are associated with Cu-Fe system laser deposited functionally graded components, which allow combining good oxidation resistivity, antifrictionality, thermal, and electrical conductivity of copper with mechanical strength, processability, and corrosion resistance of stainless steel. The main issue, which appears in the case of laser deposition of such materials, is internal stresses caused by significant inequality of physical properties of copper/bronze and steel, their limited miscibility, forming of brittle phases at the interface, and complexity of variation of mechanical and physical properties of the resulted alloy. The mentioned factors could cause various cracking in resulted parts. Specific techniques such as ultrasonic assistance, implementation of the external magnetic field, and post-treatment (hot isostatic pressing, machining), could be suggested to improve the quality of laser deposited Cu-Fe system functionally graded materials.
