No xBox 360 problems? Then count yourself as one of the blessed ones. With a failure rating of more then 50%, most customers have experienced at least one issue with their console.

The problems range from disks being scratched, to “bricking”, or possibly sometimes the “Red Ring of Death”. Some conditions like games freezing can be irritating, but most people often take on them.

Have you been playing your preferred game on your Xbox, and all of a sudden it freezes up on you? You reset the console to only notice that it freezes yet again. Taking out the disk you find that there are now scratches on it. Unfortunately, this is common with this console. As many as 1 in 9 consoles positioned flat, and 3 in 9 set on their sides have damaged disks. This is due most often to two issues, a pad absent near the reader in the disk drive, or the drive not locking the disk in place before running.

Another issue Xbox 360’s have is “bricking”. “Bricking” is a word used within the field due to the brick pattern of most electronics. Since a brick is ineffective when it comes to gadgets, when items like a game console, DVD player or equivalent quits, it’s said “useless as a brick”. Some dashboard changes have caused “bricking”. The only solution for this is to contact Microsoft to see about an exchange or repair your Xbox 360. If the console is no longer in warranty, the repair might cost anywhere from $99 and up.

The most common problem with Xbox 360’s is the “Red Ring of Death”. This word comes from the three red lights that are on around the power light in the front of the console, forming a red ring. This is caused from either a general hardware crash or a major digital failure. Either of these problems is not good. Both require your console to be presented to Microsoft for fix or replacement. The average time to receive one back is eight weeks. Due to the commonality of this issue, Microsoft stretched the 1-year warranty that these units came with to 3 years from date of purchase.

Because of the frequency of failures of the Xbox 360, there have been several lawsuits submitted. The first was soon after the release of the console. Second was filed in November of 2006, just about a year after release. This lawsuit was because of the “bricking” that was experienced after the November 1, 2006 release of a dashboard patch.

The most recent class action lawsuit made against Microsoft was in October of 2008 by Californian buyers. The filers claim that Microsoft knowingly produced faulty consoles and that they rejected to release the actual failure numbers of the consoles.

Xbox 360’s too often have problems. In an industry where only 3-5% is an acceptable failure rating, a rating of over 50% is exorbitant! What happened to the game consoles that prevailed for years and years without any problems what so ever?

Mastering of technologies CAD / CAM / CAE and application of laser 3d-scanner accelerated significantly the process of designing and manufacturing of new models of cars, reduced the number of stages in the manufacture of dies. It has become available modern methods of operative control of the geometry of parts and components, including the use of equipment for the 3d-scan.

CAD / CAM technology and 3d-scan technology are widely used to improve the quality of already produced models. The base of mathematical models is created on the basis of existing pattern equipment (master model) with technology reverse-engineering.

All surface of the detail is being scanned during 5-30 minutes. In this case the final result represents a “cloud of points» of 1.3 million pixels, which makes it possible to determine accurately even small structural elements. These mathematical models of parts allow producing quickly the quality control and adjustment of equipment, improving the geometry of the body.

Moreover, rapid prototyping makes it possible to obtain not only the drawings and plans in 3d-representation by converting electronic data of format stl, coming from CAD-systems, but also the physical parts-prototypes without their instrumental manufacture. Prototypes of engineering products, the creation of prototypes and models of buildings of architectural structures (design), interior decor, new design solutions – this is not a complete list of what in a few hours it can be converted from digital 3d-models in the physical model, ie a prototype!

The need in developing of new products and accelerated production amplifies the effect on the shift from instrumental, classical modeling techniques to new, more flexible, using rapid prototyping technology (RP). Manufacture of prototypes and functional prototypes directly from digital data using the revolutionary technology, such as selective laser sintering (sls) will help to achieve the goal of maximum economy of time.

The surfaces, defined according to 3d-scanning, are processed and transformed into a model that should be exported to a file of new format. STL-file – is standard input data for any process of rapid prototyping. Shifting the STL-file on the machine for rapid prototyping, you can make copies of the scanned model. And sometimes this is the only way to recreate a unique product which has no design documentation.

In the process of manufacturing three-dimensional model in the digitized file is virtually cut into thin layers. The machine is guided on them. After all, in essence a rapid prototyping (RP) – is a layer by layer modeling of solid construction in accordance with the geometry of the CAD-model. Innovative technology creates a prototype layer by layer, using the original material.
The building processes are largely automated and allow obtain high quality and relatively inexpensive model, spending on their production hours, not days and weeks, as when using traditional methods.

Over the recent decades rapid prototyping services managed with solving lots of tech problems occurring when trying to present a product, design or model. Have you ever faced such a problem too? Then you are invited to check out this rapid prototyping methodology site.

And don’t forget that we live in the world of digital technologies. Bear in mind that modern web technologies give you a unique chance to try and to find anything you might need. Take advantage of them to search for cheap rapid prototyping. If you want to be aware of new publications on the topic subscribe to the RSS feed on this blog.

Having replaced the traditional methods of physical models for future industrial production (manufacture of plastic foam, wood, wax, hand or even on CNC machines), rapid prototyping systems have made a genuine revolution. They opened the inexhaustible possibilities for creative engineers and designers in various industries.

Today in many areas of business three-dimensional (3d) model of real objects are increasingly demanded. People model products, cars, houses. Visualization – is the most reliable way to preview and objective assessment of the outcome of the project, because the three-dimensional models have a high level of interactivity and realism. And it has become quite easy to get them due to the development of computer technology.

Go to the visual world.

To construct 3d-models, it is used a physical object, its photos or 2d-images (thumbnails). And if it is more or less clear with the latter two methods, since it is successfully combined the growing capability of the planar-up and processing the data using sophisticated computer programs, how to be with a real object? You will agree, it cannot be inserted in the scanner. But we would like to behold how it will be seen, for example, invented new aileron on the existing airplane wing.

But nothing could be simpler! To do this, there is non-contact laser 3d-scanning of surface of objects (technical products, architectural elements, etc.) with subsequent processing of electronic data obtained using special software. The experts have hand-held laser scanners. Here are the advantages of such devices:

• The possibility of 3d-scanning of bulky and heavy objects on the ground;

• High speed and quality of scanning facilities;

• Application of laser 3d-scanning does not cause mechanical damage and other types of scanned objects;

• The ability to convert files under different software to work with 3d-objects;

• The possibility of creating 3d-images of objects, touching to which is undesirable or impossible in principle.

Reverse engineering – is a means of obtaining three-dimensional data in computerized form from physical models or products. It has clear advantages, coupled with effective use of other technologies to save time. This technology adds flexibility in the development of future models, and in the production of prototypes.

Designer is not obliged more to limit his imagination beyond the traditional methods of production. Now he can do such geometric forms that were previously impossible to be executed. With the help of prototyping of models you may build internal structures and cavities. Focusing on the final product, the designer can express his individuality in “free” three-dimensional geometry.

All the world’s leading automakers are using CAD / CAM technology and laser-3d-scan in the design and manufacture of automobiles. According to these technologies, body parts of new models are designed with the help of computers; it is created the base of mathematical 3d-models, functioning as a reference.

The number of challenges facing today’s manufacturers from different industries is as large as existing alternatives to address them. It is difficult to understand them, not to mention the comparison of economic and other indicators of the appropriateness of applying.

Suggested methods for rapid prototyping and replication differ according to the type of consumables and methods of exposure to such a material.

All the technologies of rapid prototyping are usually referred to the methods based on the addition of material (in contrast to the classical mechanical treatment). The technologies are adopted to classify according to the type of consumables (liquid, powder and solid sheet).

The processes that use liquid consumables are subdivided, in turn, in the curing processes through contact with the laser, solidification of electro charged liquids or pre-hardening molten material.

The processes that use powdered materials carry a bond of particles through the laser or the selective application of binder components. Processes that use as consumables solid sheet can be classified by the method of their connection – a laser, or a layer of adhesive.

Let us examine in more detail two technologies.

Helisys (LOM). It is one of the cheapest technologies RP. It is especially effective for the manufacture of solid-state components and parts with a wall thickness of 3 mm. It is used mainly to assess the style, constructive solutions. In appearance the prototypes produced by this technology are similar to wood ones. In physical characteristics – wood are superior and used in metallurgical production for tooling (casting into the ground, casting investment casting). Also the prototypes obtained by this technology are used as master models for replication in silicone forms of technology MCP / HEK. The surface can be painted and brought to the simulation of plastic or plastic. The prototypes are water-resistant and environmentally safe.

Brief description of the technology: The detail is cultivated by successive layer-gluing of special thermal paper. At each layer the corresponding cross section is cut by laser. After completion of construction the embracing excess material is removed. Device LOM 1015 allow receive details of dimensions to 381-254-355 mm, positioning accuracy of laser + / -0.25 mm. Prototypes with large dimensions are made in installments with subsequent assembly. It is guaranteed the compliance with the collected details of the design documentation.

Technology Stratasys (FDM). The technology of aimed melting allows getting prototypes and designs of ABS – plastic and melting wax. This technology is the most effective for getting thin-walled parts. The range of applications – are exhibition samples, prototypes and designs to verify the collection, design and style. They are also used for getting master models for replication in silicone forms. The models made of high-melting wax are used in metallurgy for investment casting.

Brief description of the technology: Consumables in the filamentous form is fed into an injection head, where it is heated to the melting temperature and extruded through a nozzle. Head moves along the contour of the current cross-section details, and squeezed material, congealing, forms a part layer by layer. Device FDM 2000 can receive details of up to 245-245-245 mm. Positioning accuracy of the injection head is + / – 0, 25 mm.

Technology Stereo Lithography (SLA). It is based on curing a photosensitive liquid polymer under the effect of exposure of ultraviolet radiation (UV). It lets get prototypes and samples with different physical and mechanical properties. It is primarily used for prototyping to verify design and collection, as well as master models for further replication in silicone forms. It is developed supplies which allow us to obtain functional prototypes with different physical and mechanical properties, heat resistance, transparency, etc.

Technology overview: The model is built on a platform that moves in the direction of the construction of models (Z) and inside the tub with liquid polymer. Ultraviolet radiation is produced by helium-cadmium, or fixed transmitter (laser gun) and is positioned on the polymer surface with a movable mirror. Absorption and dispersion of the light beam occurs only directly in the vicinity of the surface, resulting in the formation of three-dimensional pixels (volume elements). After polymerization of the current cross-section details the model is immersed in a bath on the value of the thickness of the next hardened layer. The thickness of the layer and the surface is calibrated by special scraper – Raquel. The range of settings allows you to receive details with dimensions 500?500?500 mm. Accuracy of laser positioning is + / – 0,25 mm.

Technology Selective Laser Sintering (SLS). The technology is based on sintering of finely dispersed particles of consumables under the influence of CO2 laser. Consumable (powder) is preheated to a temperature close to the melting temperature of the material (or glue). In the market there are equipment of the two companies – world leaders “DTM” and “EOS”, differing in the flexibility of supplies. As supplies it is used a variety of special plastics (including glass fiber), sand and metal powders. As a result of the use of technology you can get functional prototypes of plastic parts, sand molds and cores for the steel industry, the models for investment casting and metal parts or pieces forming elements molds. This technology is used primarily for single functional prototypes or as an alternative to replication in silicone forms for getting the party of details in a few dozen copies.

Technology overview: The current cross-section of the detail is sintered by laser on the value of the layer consumables (about 0, 15 mm.). After that, the platform is lowered by the amount of the next layer; the next portion of consumables is released from the cartridge, applied and calibrated by rolling roller. Device DTM Sinterstation 2500 plus allows you to receive details with dimensions up to 300?330?430 mm.

Technology MCP / HEK. It is an effective method of getting small parties by casting in a vacuum in the flexible silicone molds without making major equipment. As expendable material for obtaining copies it is used two-component polyurethane. The technology allows receiving copies of a 100% similarity in geometry and texture of the surface (including pad printing, label marker on a glossy surface). It is possible receiving of non-transparent parts and transparent, colorless and colored (lighting elements). It is also possible to obtain the elastic elements (seals, damping elements, shoe soles, etc.) The silicone form made by master model allows you to make an average of 10 – 25 copies, and then you must repeat the process.
