Книги з теми "3D printing model"

The tutorial is an introductory course to the study of the basics of geometric modeling for 3D printing using the programming language OpenSCAD and is built on the basis of descriptions of instructions for creating primitives, determining their properties, carrying out transformations and other service operations. It contains a large number of examples with detailed comments and description of the performed actions, which allows you to get basic skills in creating three-dimensional and flat models, exporting and importing graphical data. Meets the requirements of the Federal state educational standards of higher education of the last generation. It can be useful for computer science teachers, students, students and anyone who is interested in three-dimensional modeling and preparation of products for 3D printing.

Volume 23A provides a comprehensive review of established and emerging 3D printing and bioprinting approaches for biomedical applications, and expansive coverage of various feedstock materials for 3D printing. The Volume includes articles on 3D printing and bioprinting of surgical models, surgical implants, and other medical devices. The introductory section considers developments and trends in additively manufactured medical devices and material aspects of additively manufactured medical devices. The polymer section considers vat polymerization and powder-bed fusion of polymers. The ceramics section contains articles on binder jet additive manufacturing and selective laser sintering of ceramics for medical applications. The metals section includes articles on additive manufacturing of stainless steel, titanium alloy, and cobalt-chromium alloy biomedical devices. The bioprinting section considers laser-induced forward transfer, piezoelectric jetting, microvalve jetting, plotting, pneumatic extrusion, and electrospinning of biomaterials. Finally, the applications section includes articles on additive manufacturing of personalized surgical instruments, orthotics, dentures, crowns and bridges, implantable energy harvesting devices, and pharmaceuticals.

An illustrated guide to exploring the Universe in three dimensions. Astronomers have made remarkable discoveries about our Universe, despite their reliance on the flat projection, or 2D view, the sky has offered them. But now, drawing on the vast stores of data available from telescopes and observatories on the ground and in space, astronomers can now use visualization tools to explore the cosmos in 3D. In Stars in Your Hand, Kimberly Arcand and Megan Watzke offer an illustrated guide to exploring the Universe in three dimensions, with easy-to-follow instructions for creating models of stars and constellations using a 3D printer and 3D computer imaging. Stars in Your Hand and 3D technology make learning about space an adventure. Intrigued by the stunning images from high-powered telescopes? Using this book, you can fly virtually through a 3D spacescape and hold models of cosmic objects in your hand. Arcand and Watzke outline advances in 3D technology, describe some amazing recent discoveries in astronomy, reacquaint us with the night sky, and provide brief biographies of the telescopes, probes, and rovers that are bringing us so much data. They then offer images and instructions for printing and visualizing stars, nebulae, supernovae, galaxies, and even black holes in 3D. The 3D Universe is a marvel, and Stars in Your Hand serves as a unique and thrilling portal to discovery.

Brachytherapy has been a popular topic for AAPM summer schools, with this marking the third time the subject has been covered (past schools on the topic were held in 1994 and 2005). This book was developed for the AAPM 2017 Summer School in Portland, Oregon, held in conjunction with the American Brachytherapy Association. From Joann Prisciandaro in Medical Physics…"Overall, this text is well written and provides a nice summary of current and developing clinical brachytherapy practice patterns. …from my perspective as a practicing brachytherapy physicist and educator, this text will make an extremely useful reference and will certainly be added to my list of required reading for residents and graduate students." This book is more than a comprehensive overview of the brachytherapy tools and techniques used in a modern clinic. The book also looks at numerous exciting approaches currently under development. Topics include HDR and LDR brachytherapy for the prostate, general planning and model-based dose calculation algorithms, intensity-modulated brachytherapy, electronic brachytherapy sources and techniques, and brachytherapy advances for treating skin, gynecological, and breast cancer. Some of the promising new techniques covered include focal therapy, the use of 3D printing to augment treatment, advances in needle tracking, in vivo dosimetry, and the use of robotics in brachytherapy.

Today, the scientific and technological sphere has become the main arena of competition between countries in the world, and the use of new technologies, especially in the field of armaments, is considered as one of the most important levers of geopolitics. Such technologies are a key for expanding the capabilities of the state's defense capabilities and achieving national security goals, priory to military and military-economic, as well as scientific and technological security. Today, the identification of scientific and technological key areas of military development is used to determine the priorities of scientific and technological development and military-technical policy which is crucial for the process of creating promising models of armaments and military equipment. The introduction of the latest technologies in the military is difficult to imagine without the use of computer and other telecommunications equipment, artificial intelligence technology, military robotics, quantum and space technology, 3D printing and biotechnology. Although they all are already used in the military and security spheres, still monitoring innovation and new technologies in the military are important for understanding not only future wars, but also global security. This study reviews global technological trends based on the analysis of publications of foreign consulting agencies, international organizations and forecasting and analytical research conducted by the author's methodology. The data upon perspective directions of development of scientific and technological researches in the military sphere on the basis of the analysis of publishing activity of a DB of Web of Science and a DB of patents of Derwent Innovations is provided. In particular, the range of new directions of technological development of the military sphere has been expanded and clarified not only in general, but also specified by types and kinds of troops. This analysis allowed us to determine that the areas of development claimed by international organizations and consulting agencies correlate with the areas identified by the authors of the study on the basis of scientometric and patent analysis. At the same time, the forecasted promising areas of research, determined by scientometric analysis of Web of Science publications, more or less completely coincide with the forecasts of NATO, RAND Corporation.
