Effect of Molding Material Temperature on Workpiece in FDM

International Journal of Plant Engineering and Management 2015年第3期20卷 170-178页

作者： PANG Xue-qin REN Chong HAN Lei-gang Engineering Training Centre Inner Mongolia University of Science & Technology Mechanical Engineering School Inner Mongolia University of Science & Technology

Fused deposition molding is an advanced kind of rapid prototyping technology. On the accuracy of the forming process, the research on the temperature of the molding material is based on the analysis of the forming parameters. The influence of the tenlperature of the molding material on the specimen is reasonably described by the actual forming part and the finite element analysis model. The experimental results show that the temperatur（ of the molding material is less affected by the temperature of the molding material in a certain range. This will lay the theoretical foundation for the formation of the molding technology in the future

Centrifuge shaker is deemed as one of the most advanced and effective experiment equipment in geotechnical anti-earthquake field. In this paper, we pay close attention to three key technical issues encountered in the construction process of Chinese largest uniaxial centrifuge shaker, including the dynamic coupling characteristic between light-flexible base, hydraulic power element and soil model, and the influence of centrifuge vibration synthesis environment to three stage servovalve's dynamic performance, as well as the servo control strategy aiming at better control performance. For these three issues, relevant research achievements of other scholars and our original efforts are briefly overviewed. Finally, the mechanical and hydraulic system, electronic control system, software system of the centrifuge shaker prototype is reported in detail.

Understanding new technology adoption in the apparel and footwear industry within a social framework: A case of rapid prototyping technology

引用

International Journal of Fashion Design, technology and Education 2009年第2-3期2卷 101-112页

作者： Park, Juyeon DeLong, Marilyn Department of Design and Merchandising Colorado State University Fort Collins CO 80523 1574 Campus Delivery United States Department of Design Housing and Apparel University of Minnesota St Paul MN 55108 240 McNeal United States

This study explores the current phenomenon of user-technology negotiation associated with new technology adoption in the apparel and footwear industry. A theoretical framework was proposed as a construct, and a case study was performed to evaluate the proposed framework. In partnership with a world leading footwear company, its newly patented prototyping technology, named the virtual sampling system (VSS), was used to generate empirical data. A web survey was administered to the employees and quantitative analysis was performed to assess the relationships among the study variables. Frequency of use was the most determinant external variable to identify relative social groups to categorise the technology users by the levels of their initial expectation of the technology, satisfaction with training sessions, and evaluations of the company's performance with the use of the technology. Based on the case study findings, a strategy for increasing the efficiency of internal communications was suggested to the participant company. © 2009 Taylor & Francis Group, LLC.

Improving part quality during rapid prototyping is the important problem. The part errors during rapid prototyping is classified in dimension error, shaped error and roughness of surface. The shaped errors have many forms in fused deposition modeling (FDM), largely including warpage deformation, stair-stepping effect, and so on. There are several reasons for the errors, including principle, process and equipment. The reasons inducing these errors are analyzed, and the measures improving part accuracy are proposed.

Cerebrovascular Biomodeling for Aneurysm Surgery: Simulation-Based Training by Means of rapid prototyping Technologies

SURGICAL INNOVATION 2011年第3期18卷 294-306页

作者： Wurm, Gabriele Lehner, Michael Tomancok, Berndt Kleiser, Raimund Nussbaumer, Karin Landes Nervenklin Wagner Jauregg Dept Neurosurg A-4021 Linz Austria

Objective: Opportunities for developing procedural skills are progressively rare. Therefore, sophisticated educational tools are highly warranted. Methods: This study compared stereolithography and 3-dimensional printing for simulating cerebral aneurysm surgery. The latter jets multiple materials simultaneously and thus has the ability to print assemblies of multiple materials with different features. The authors created the solid skull and the cerebral vessels in different materials to simulate the real aneurysm when clipped. Results: Precise plastic replicas of complex anatomical data provide intuitive tactile views that can be scrutinized from any perspective. Hollowed out vessel sections allow serial clipping efforts, evaluation of different clips, and clip positions. The models can be used for accurate prediction of vascular anatomy, for optimization of teaching surgical skills, for advanced procedural competency training, and for patient counseling. Conclusion: Simultaneous 3-dimensional printing is the most promising rapid prototyping technique to produce biomodels that meet the high demands of neurovascular surgery.

This work deals with the problem of casting production from high-aluminum cast iron Al22D. This cast iron is characterized by unique combination of properties [1-3]: high heat-resistance in corrosive gases medium especially containing sulfurous gases;relatively low density in comparison with gray iron and satisfactory mechanical properties. In addition, castings made from high aluminum cast iron Al22D are required in many areas of mechanical engineering. However, obtaining high-quality products from this cast iron is a particular problem due to its low-casting properties, especially its high tendency to gas saturation, oxidization and forming scabs, shrinkage and gas-shrinkage defects. Therefore, the aim of this work is the study of the castings feeding parameters. In addition, the technology of "exhaust manifold" casting of internal combustion engine designed to work in forced mode was developed on the basis of the obtained results.
