“…This ap-proach is inspired by the recycling pathway using laser-or electron-beam-based equipment with simplified control of the beam used just for melting scrap material into ingots [171][172][173], but it has the advantage of conducting essentially full recycling at the manufacturing site without any need for costly and hazardous transportation of powders to a specialized recycling site. Repairing and remanufacturing using additive manufacturing [143,[178][179][180][181][182]. This review also provides a brief overview of laser shock peening, one of the potential industrial post-processing routes allowing for reducing residual stresses in additively manufactured components and increasing their value as CRM-reducing and CRM-sparing manufacturing routes.…”

“…Further progress in solving CRM-related challenges belongs to the developing trends in AM and its deep integration with other processing modalities. Several AM-related possibilities to reduce and optimize the use of CRMs and CRM-based materials are discussed in this review: Use of hybrid manufacturing [ 138 , 146 , 174 ]; Production of multimaterial components [ 175 , 176 ]; Production of functionally graded materials (FGMs) [ 153 , 165 , 177 , 178 ]; Repairing and remanufacturing using additive manufacturing [ 143 , 178 , 179 , 180 , 181 , 182 ]. …”

The term “critical raw materials” (CRMs) refers to various metals and nonmetals that are crucial to Europe’s economic progress. Modern technologies enabling effective use and recyclability of CRMs are in critical demand for the EU industries. The use of CRMs, especially in the fields of biomedicine, aerospace, electric vehicles, and energy applications, is almost irreplaceable. Additive manufacturing (also referred to as 3D printing) is one of the key enabling technologies in the field of manufacturing which underpins the Fourth Industrial Revolution. 3D printing not only suppresses waste but also provides an efficient buy-to-fly ratio and possesses the potential to entirely change supply and distribution chains, significantly reducing costs and revolutionizing all logistics. This review provides comprehensive new insights into CRM-containing materials processed by modern additive manufacturing techniques and outlines the potential for increasing the efficiency of CRMs utilization and reducing the dependence on CRMs through wider industrial incorporation of AM and specifics of powder bed AM methods making them prime candidates for such developments.
