“…Currently, mainly AM powder methods with metals and their alloys are used to build fully functional and responsible mechanical parts. Elements of this type are used in the aerospace, offshore, and energy sectors [ 36 , 74 , 75 ] as well as in the automotive, electronics, medical [ 76 , 77 ] and tool industries [ 78 , 79 ], among others.…”

High requirements imposed by the competitive industrial environment determine the development directions of applied manufacturing methods. 3D printing technology, also known as additive manufacturing (AM), currently being one of the most dynamically developing production methods, is increasingly used in many different areas of industry. Nowadays, apart from the possibility of making prototypes of future products, AM is also used to produce fully functional machine parts, which is known as Rapid Manufacturing and also Rapid Tooling. Rapid Manufacturing refers to the ability of the software automation to rapidly accelerate the manufacturing process, while Rapid Tooling means that a tool is involved in order to accelerate the process. Abrasive processes are widely used in many industries, especially for machining hard and brittle materials such as advanced ceramics. This paper presents a review on advances and trends in contemporary abrasive machining related to the application of innovative 3D printed abrasive tools. Examples of abrasive tools made with the use of currently leading AM methods and their impact on the obtained machining results were indicated. The analyzed research works indicate the great potential and usefulness of the new constructions of the abrasive tools made by incremental technologies. Furthermore, the potential and limitations of currently used 3D printed abrasive tools, as well as the directions of their further development are indicated.

“…However, diamond is difficult to be machined, so it's expected to use 3D printing for diamond material development to get parts with superior properties and flexible configurations. Yang et al [1] used selective laser sintering (SLS) to inlay 300-500 μm diamond particles regularly on Ni-Cr alloy and fabricated metal-bonded diamond grinding wheels with superior grinding performance. Fox et al [2] prepared diamond-Ti composites with great potential for medical implant applications through laser metal deposition (LMD).…”

3D printing is a revolutionary technology that can easily produce complex shapes with low cost and high efficiency. In recent years, technologies for 3D printing have been developed rapidly for polymers, metals, ceramics, and composite materials. Due to its advantages in configuration, 3D printing has also been expected to be a powerful method for preparing diamond-based composites and promoting the applications of diamonds as well. In this paper, stereolithography printing technology is employed to prepare diamond-based composites with special attention to slurry preparation and its stereolithography performance. The impact of diamond particle size, solid loading, and exposure time on the photocuring performance of the diamond slurry are investigated systematically. In addition, the correlation between the thermal conductivity of the printed materials with particle size and solid loading is also studied. The highest thermal conductivity in this study is 1.32 W/(m·K), achieved with an average particle size of 15 μm and a solid loading of 75 wt%. The results show the great potential of preparing diamond-based composites by 3D printing and provide theoretical and technical guidance for further research.

“…It was reported that the diamond grits did not fall off, even after the grinding processes involving a heavy load. In addition, in 2017 Yang tentatively manufactured a multilayer diamond tool via 3D printing technology [23]. First, the diamond grits were randomly sprayed onto alloy powders and sintered by a laser beam, according to the design requirements; the diamond grits that were not sintered were wiped away using a sparger.…”

Diamond tools with orderly arrangements of diamond grits have drawn considerable attention in the machining field owing to their outstanding advantages of high sharpness and long service life. This diamond super tool, as well as the manufacturing equipment, has been unavailable to Chinese enterprises for a long time due to patents. In this paper, a diamond blade segment with a 3D lattice of diamond grits was additively manufactured using a new type of cold pressing equipment (AME100). The equipment, designed with a rotary working platform and 16 molding stations, can be used to additively manufacture segments with diamond grits arranged in an orderly fashion, layer by layer; under this additive manufacturing process, at least 216000 pcs of diamond green segments with five orderly arranged grit layers can be produced per month. The microstructure of the segment was observed via SEM and the diamond blade fabricated using these segments was compared to other commercial cutting tools. The experimental results showed that the 3D lattice of diamond grits was formed in the green segment. The filling rate of diamond grits in the lattice could be guaranteed to be above 95%; this is much higher than the 90% filling rate of the automatic array system (ARIX). When used to cut stone, the cutting amount of the blade with segments made by AME100 is two times that of ordinary tools, with the same diamond concentration. When used to dry cut reinforced concrete, its cutting speed is 10% faster than that of ARIX. Under wet cutting conditions, its service life is twice that of ARIX. By applying the machine vision online inspection system and a special needle jig with a negative pressure system, this study developed a piece of additive manufacturing equipment for efficiently fabricating blade segments with a 3D lattice of diamond grits.
