“…Stucker et al [124] by means of indirect SLS and normal sintering process, manufactured copper-based zirconium diboride electrode that achieved better results than copper, graphite and W-Cu electrodes regarding wear and material removal rate. Czelusniak et al [157] applied SLS to directly manufacture ZrB 2 -CuNi EDM electrodes. The authors compared EDM performance at roughing, semi-finishing and finishing regime with LS copper electrodes and electrolytic copper.…”

Over the years, sinking electrical discharge machining has become one of the most important production technologies to manufacture very accurate three-dimensional complex components on any electrically conductive material. This article reports a literature review on the diversity of conventional and non-conventional materials that are used or have potential to be used as EDM electrodes. In addition, additive manufacturing of EDM electrodes are also reviewed.

“…By repeating this process a number of times a solid 3D object of intended shape could be fabricated [4]. Previous works in recent years have demonstrated the feasibility of using this method to build 3D part from a range of metal powders, including pure iron [5], stainless steel [6][7][8], hard tool steel [9,10], titanium alloys [11][12][13][14][15], nickel-base superalloys [4,[16][17][18], cobalt-chromium alloys [19][20][21], copper compounds [22][23][24], aluminum alloys [15,[25][26][27], refractory metals [28][29][30][31], metal matrix composites (MMCs) [2,[32][33][34][35], and even dissimilar metals (functionally gradient materials) [36,37]. Glass [38,39] and metal glass [40][41][42], quasicrystals [43] are also reported as potential SLM materials in this year.…”

“…Carbides are the most commonly used ceramics for MMCs, such as SiC/Al (Simchi and Godlinski, 2010), TiC/(Fe,Ni) (Gåård et al , 2006) and TiC/Ti (Gu et al , 2012a, 2014b). Oxide ceramics and others can also be used (Leong et al , 2002; Czelusniak et al , 2014). Special functionally graded parts built by SLM processing were reported via the addition of small amounts of zirconia within the nickel alloy, which can be used in high temperature applications (Mumtaz and Hopkinson, 2007).…”

Purpose This paper aims to provide a review on the process of additive manufacturing of ceramic materials, focusing on partial and full melting of ceramic powder by a high-energy laser beam without the use of binders. Design/methodology/approach Selective laser sintering or melting (SLS/SLM) techniques are first introduced, followed by analysis of results from silica (SiO2), zirconia (ZrO2) and ceramic-reinforced metal matrix composites processed by direct laser sintering and melting. Findings At the current state of technology, it is still a challenge to fabricate dense ceramic components directly using SLS/SLM. Critical challenges encountered during direct laser melting of ceramic will be discussed, including deposition of ceramic powder layer, interaction between laser and powder particles, dynamic melting and consolidation mechanism of the process and the presence of residual stresses in ceramics processed via SLS/SLM. Originality/value Despite the challenges, SLS/SLM still has the potential in fabrication of ceramics. Additional research is needed to understand and establish the optimal interaction between the laser beam and ceramic powder bed for full density part fabrication. Looking into the future, other melting-based techniques for ceramic and composites are presented, along with their potential applications.
