Additive manufacturing processes, used for more than 25 years, are no longer confined to rapid prototyping applications. Mostly used nowadays in niche markets (medical applications, aerospace. . . ) to manufacture metallic parts, they should provide improvements in terms of time-to-market, ecological impact and design compared to traditional industrial processes. Current metallic additive manufacturing studied in this paper are Selective Laser Sintering, Direct Metal Laser Sintering, Selective Laser Melting, Electron Beam Melting and Direct Metal Deposition. The performances of these processes are investigated through criteria derived from the time cost quality triangle and some prospects concerning these processes are given.

The concept of additive manufacturing is put forward on the basis of the nowadays research hotspot-3D print. This paper focuses on the main branch technology of additive manufacturing, i.e., electron beam melting (EBM) in high energy beam rapid manufacturing area, enumerating the advantages of EBM compared with laser rapid prototyping and introducing its process principle as well as its research status. The application situation of EBM in aerospace especially it’s utility in aircraft engine and industrialization of industrial aspects was also introduced, and its development prospect in the future was forecasted.

“…3D printing has also been referred to as solid free-form manufacturing, computer automated manufacturing, layered manufacturing, and Rapid Prototyping & Manufacturing (RP&M). So far, many 3DP techniques have been developed, including Stereolithography (SLA) [1], Fused Deposition Modeling (FDM) [2], Laminated Object Manufacturing (LOM) [3], Selective Laser Sintering (SLS) [4], Selective Laser Melting (SLM) [5], Electron Beam Selective Melting (EBSM) [6], and Laser Engineered Net Shaping (LENS) [7]. These 3DP techniques not only have already been applied in many traditional areas successfully, but also bring some new design and manufacturing ideas [8]- [11].…”

Tool Path Generation is one of the important steps in 3D printing (3DP) processes. An extendable tool path generation software is designed aimed at supporting all 3DP processes in this paper. At first, an extendable architecture is created based on the principle of tool path generating which all 3DP processes should follow. Then, the Graphical User Interface (GUI) is designed with a Visual Studio like style and OpenGL is used to display slicing layers and tool paths in both 2D and 3D. At last, the parallel computing is introduced to save the generation time. Experiment result shows that, the presented software works faster than the commercial software CTools.
