“…For example, Selective Laser Erosion and/or laser re-melting after each layer of a selective laser melting (SLM) process increases part density and reduces surface roughness [362]. Cold work by high-pressure interpass rolling of Ti-6Al-4V parts produced by SLM results in a refined, equiaxed, and texture-free microstructure [202] [203] with mechanical properties that are higher than the forged material (ultimate tensile strength as high as 1078 MPa, and ductility up to 13%) [202].…”

The past few decades have seen substantial growth in Additive Manufacturing (AM) technologies. However, this growth has mainly been process-driven. The evolution of engineering design to take advantage of the possibilities afforded by AM and to manage the constraints associated with the technology has lagged behind. This paper presents the major opportunities, constraints, and economic considerations for Design for Additive Manufacturing. It explores issues related to design and redesign for direct and indirect AM production. It also highlights key industrial applications, outlines future challenges, and identifies promising directions for research and the exploitation of AM's full potential in industry.Design, Manufacturing, Additive Manufacturing

“…One common method to address these anisotropies is to modify the part [25][118] [328] or assembly [232] orientation to minimize their impact. Other options include finishing operations after each layer [362] (Fig. 41), finishing operations such as chemical [35][254] (Fig.…”

“…The molten polymer material was subsequently injected into the remaining cavity with adhesion taking place between the metal and the polymer (Bariani et al, 2007;Baesso and Lucchetta, 2007). Yasa et al (2011) used selective laser melting (SLM) to build 2D layers and after building each layer, the same laser source was applied to heat the solidified layer as a laser erosion process, showing significant improvement in surface quality in comparison to individual SLM.…”

Today, hybrid manufacturing technology has drawn significant interests from both academia and industry due to the capability to make products in a more efficient and productive way. Although there is no specific consensus on the definition of the term 'hybrid processes', researchers have explored a number of approaches to combine different manufacturing processes with the similar objectives of improving surface integrity, increasing material removal rate, reducing tool wear, reducing production time and extending application areas. Thus, hybrid processes open up new opportunities and applications for manufacturing various components which are not able to be produced economically by processes on their own. This review paper starts with the classification of current manufacturing processes based on processes being defined as additive, subtractive, transformative, joining and dividing. Definitions of hybrid processes from other researchers in the literature are then introduced. The major part of this paper reviews existing hybrid processes reported over the past two decades. Finally, this paper attempts to propose possible definitions of hybrid processes along with the authors' classification, followed by discussion of their developments, limitations and future research needs.
