The unique capability of this technology to produce intricate geometries with customizable material properties has made it a widely interesting and welcome development among scientists, industry and the general public. AM represents an innovative manufacturing technology, and is set to transform production processes from design to manufacture, and to eventual distribution to end users, ultimately leading to an increase in energy efficiency and a reduction in gas emissions for future generation of industries. Additive manufacturing (AM) or three-dimensional (3D) printing, in contrast, is controlled material addition, implemented by successively depositing layers of material until a predesigned shape is formed. Three-dimensional objects were created by successively cutting material away from a solid block, by scraping, machining, turning or dissolving.

Also, proponents of AM technology rarely take into account the overall life-cycle cost and risks of failure of the manufactured part. Very little consideration is being given to the adverse effects of the seemingly unstoppable advancement moreВ В» of AM technology and unrestricted access to 3D printing techniques. However, most research and media attention has been focused on the ingenuity of this ground-breaking technology and its wide range of possibilities.

Wohlers Report 2013, available as a color PDF, provides a review and analysis of additive manufacturing and 3D printing worldwide.This edition marks the 18th consecutive year of its publication. The paper also presents potential options for curbing these risks, and otherwise adapting to the eventualities which, with certain inevitable factors in play, may lie beyond control. Matters discussed include life-cycle cost analysis, end-product safety and quality assurance/control, regulation gaps, digital piracy, and resulting loopholes in safety and national security. This paper brings to light some scientific and policy risks and challenges concerning the material science and engineering aspects of these issues.

For the nuclear moreВ В» industry, the supply chain is always an issue for reactor service. Additive manufacturing of stainless steel (SS) components can add business benefits on fast delivery on repair hardware, installation tooling, new design prototypes tests, etc. Such opportunities may be observed during a plant refueling outage and AM parts can be rapidly custom designed, manufactured and deployed within the outage interval. This technology can provide the capability to rapidly fabricate complex parts that may be required to enhance the integrity of reactor internals components. Metal additive manufacturing (AM), or metal 3D printing is an emergent advanced manufacturing method that can create near net shape geometries directly from computer models.

The detailed objectives are listed as follows: (1) Evaluate nuclear related properties of AM 316L SS, including microstructure, tensile properties, impact toughness, stress corrosion cracking (SCC), corrosion fatigue (CF), irradiation effects, and irradiation assisted stress corrosion cracking (IASCC). The main objective of this program was to generate research data to address all these technical gaps and establish a commercial practice to use AM technology in the nuclear power industry. Technical gaps exist, which limit this technology adoption in the nuclear industry, which includes high manufacturing cost, unknown risks, limited nuclear related data, lack of specification and qualification methods, and no prior business experience. Little work has been done to define and evaluate the material requirements for nuclear applications. While extensive work has been conducted regarding additively manufacturing of austenitic SS parts, most efforts focused only on basic attributes such as porosity, residual stress, basic tensile properties, along with components yield and process monitoring. In the meantime, the capability of generating complex geometries and functional gradient materials will improve the performance, reduce the overall component cost, plant asset management cost and increase the plant reliability by the improvement in materials performance in nuclear environments.

Examples include TOOOL (The Open Organization of Lockpickers), the Longhorn Lockpicking Club, Sportsfreunde der Sperrtechnik - Deustcheland e.V., though there are many others. They can be found all over the world, from Europe to the US and now South East Asia. Increasingly, however, nonprofit sporting organizations and clubs are doing this. Traditionally, locksmiths, corporations, and government organizations have been largely responsible for developing standards, uncovering vulnerabilities, and devising best security practices. Today in the world of physical security, Pro-Ams are playing an ever-increasing role.

When members are asked why they participate in these hobbyist groups, they usually reply (with gusto) that they do it for fun, and that they view defeating locks and other security devices as an interesting and entertaining puzzle.
