Abstract: Additive manufacturing (AM) has provided huge versatility in geometry and materials, allowing new products and processes in several areas to be created. Laser Engineered Net Shaping (LENS) is an additive manufacturing process created in 1995 that allows building high-density metals and ceramics parts with no need for further operation. This manuscript aims to study the scientific literature about the process of Laser Engineered Net Shaping related to ceramics. After a systematic review, the articles were group… Show more

“…For ceramic AM, multi-step processes are the most common. Additives and binders are used to create a green body that is subsequently treated for debinding (to eliminate the organics) and sintered (to increase density) [5,13,18]. The debinding is a critical step to successfully obtaining the ceramic parts and the heating rates must be suitable to avoid cracks and/ or delamination [5,19,20].…”

“…In order to assess and analyze recent review articles in this area, a Scopus search was conducted in April 2023 for the specific time frame of 2018–2023. This search resulted in 165 review articles on ceramic additive manufacturing or some subset of that topic 1,3–166 . Figure 1 shows a graphical representation of the number of review articles separated into five focus areas.…”

“…The resulting laser clads are narrower than those in any other process, and as a consequence, the final part does not require either rough or finish machining. The additive nature of the LENS process makes it a more resource-efficient manufacturing technology since less waste is generated in comparison to the subtractive techniques [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Additionally, a less amount of the material could be used for the part repair, which is extremely important in terms of the application of nickel-based alloys.…”
