Maturation of powder-bed additive manufacturing (AM) is essential for the business benefit the rapid adoption of AM offers to industry. One of the principal challenges in powder-bed AM is the mitigation of distortion due to material shrinkage and residual stresses induced during the build process. In order to address this, a new methodology for distortion compensation is developed and presented in this paper. The novelty of the methodology lies in the use of a mathematical model for pre-distorting the design geometry based on 3D optical scanning measurement data. The methodology has been applied to two industrial Inconel 718 components (a turbine blade and an impeller). It was experimentally demonstrated that distortion compensation is achievable using the proposed methodology. The results showed the compensation methodology reduced distortion from approximately ±300 μm to approximately ±65 μm for both components. In summary, the novel methodology can be used to deliver near-zero distorted parts for industry using powder-bed AM processes. 相似文献

Additive manufacturing (AM) technique allows the creation of parts with a high degree of design complexity by building three-dimensional (3D) parts layer-by-layer. Many of the current restrictions of design for manufacturing (DFM) as well as design for assembly (DFA) are no longer applicable for AM due to the lack of needs for tooling. Instead, it is critical to establish the manufacturing limits and design guidelines to achieve optimal production outcomes. This can be achieved through manipulation of process parameters.The purpose of this paper is to establish a systematic methodology for investigating the process capability of material jetting AM techniques by using specially designed benchmark artifacts. In this study, three customized benchmarks were designed to characterize and establish the process capability of material jetting AM techniques. Each of the benchmarks was designed for different purposes. Using a benchmark, metrological studies were conducted to determine the effect of process parameters on the dimensional accuracy of fabricated part. The design limitations on special features such as thin walls and assembly-free parts fabricated using different build orientations were also evaluated. 相似文献

Rapid prototyping (RP) or layered manufacturing (LM) technologies have been extensively used to manufacture prototypes composed mainly of plastics, polymers, paper, and wax due to the short product development time and low costs of these technologies. However, such technologies, with the exception of selective laser melting and sintering, are not used to fabricate metallic products because of the resulting poor life, short cycle, poor surface finish, and low structural integrity of the fabricated parts. The properties endowed by these parts do not match those of functional parts. Therefore, extensive research has been conducted to develop new additive manufacturing (AM) technologies by extending existing RP technologies. Several AM technologies have been developed for the fabrication of metallic objects. These technologies utilize materials, such as Ni-, Al-, and Ti-based alloys and stainless steel powders, to fabricate high-quality functional components. The present work reviews the type of materials used in laser-based AM processes for the manufacture of metallic products. The advantages and disadvantages of processes and different materials are summarized, and future research directions are discussed in the final section. This review can help experts select the ideal type of process or technology for the manufacturing of elements composed of a given alloy or material (Ni, Ti, Al, Pb, and stainless steel). 相似文献
