Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Direct metal laser sintering (DMLS) is an additive metal fabrication technology developed by EOS out of Munich, Germany. The process involves use of a 3D CAD model whereby a .stl file is created and sent to the machine’s software. A technician works with this 3D model to properly orient the geometry for part building and adds supports structure as appropriate. Once this ‘build file’ has been completed, it is ‘sliced’ into the layer thickness the machine will build in and downloaded to the DMLS machine allowing the build to begin. The DMLS machine uses a high-powered 200 Watt Yb-fiber optic laser. Inside the build chamber area, there is a material dispensing platform and a build platform along with a recoater blade used to move new powder over the build platform. The technology fuses metal powder into a solid part by melting it locally using the focused laser beam. Parts are built up additively layer by layer, typically using 20 micron layers. This process allows for highly complex geometries to be created directly from the 3D CAD data, fully automatically, in hours and without any tooling.

Эта история началась с объявления в газете: Ку-клукс-клан призывает новых защитников белой расы. Рон Сталлворт, детектив полиции Колорадо-Спрингс, решает откликнуться на объявление… и получает членскую карточку ККК. Но посещать встречи клановцев он не может. Дело в том, что Рон — афроамериканец. «Самое смешное, и вместе с тем, самое жуткое в этой истории - то, что она случилась на самом деле »....
