3D printing

3D printing
An ORDbot Quantum 3D printer. 3D printing or additive manufacturing[1] is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.[2] 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes). A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control. The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields.

HP Designjet 3D Printer Now On Sale, Churns Out Solid Plastic Objects From the Desktop Remember back in January when HP announced it would bring a tabletop 3-D printer to market, at a place and time to be named later? That place and time just became a quite a bit less ambiguous. Today Stratasys, the company that is manufacturing the device for HP, announced that it has shipped the first units of the HP-branded Designjet 3D fabrication machines, which will be available in May -- but only in Europe. The Designjet 3D is based on Stratasys's Fused Deposition Modeling (FDM) technology, which turns three-dimensional CAD drawings into tangible prototypes by extruding partially molten ABS plastic in extremely fine layers one atop the other, forming the entire 3-D model in a single piece from the ground up. Designjet 3D will print in ivory-colored plastic only while Designjet Color 3D will print single-color parts in up to eight different colors (we're not sure why you can't just put a different hue of ABS plastic in the Designjet 3D).

Stereolithography How are parts built? SLA enables the building of complex, 3-D models by successively "laser-forming" cross sections of liquid resin, using data from most surface or solid modeling CAD systems.The .STL file sent to the machine is sliced into small layers and the laser is driven by the design. The liquid plastic hardens only where touched by the laser beam, and the model is built layer-by-layer, without tooling, programming, or machining. Where the polymer is sufficiently exposed to the laser's beam, it hardens down to a regulated depth. OpenAI OpenAI is a non-profit artificial intelligence research company. Our goal is to advance digital intelligence in the way that is most likely to benefit humanity as a whole, unconstrained by a need to generate financial return. Since our research is free from financial obligations, we can better focus on a positive human impact. We believe AI should be an extension of individual human wills and, in the spirit of liberty, as broadly and evenly distributed as possible. The outcome of this venture is uncertain and the work is difficult, but we believe the goal and the structure are right.

What is laptop computer? - Definition from WhatIs.com A laptop computer, sometimes called a notebook computer by manufacturers, is a battery- or AC-powered personal computer generally smaller than a briefcase that can easily be transported and conveniently used in temporary spaces such as on airplanes, in libraries, temporary offices, and at meetings. A laptop typically weighs less than 5 pounds and is 3 inches or less in thickness. Among the best-known makers of laptop computers are IBM, Apple, Compaq, Dell, and Toshiba.

Fused filament fabrication Prusa, a simple fused filament printer Fused filament fabrication is a 3D printing process that uses a continuous filament of a thermoplastic material. This is fed from a large coil, through a moving, heated printer extruder head. Molten material is forced out of the print head's nozzle and is deposited on the growing workpiece. The head is moved, under computer control, to define the printed shape.

Will 3D printing revolutionise manufacturing? 28 July 2011Last updated at 00:09 By Peter Day Presenter, In Business Loughborough University's machines can even print larger structures such as building materials With the creation of many products - including building materials - now possible at the touch of a button, will 3D printing sound the death knell for mass production? How 3D Printing Actually Works Now that 3D printing — the process of making three-dimensional solid objects from digital designs — is available and affordable to individual consumers, it's piqued a lot of interest across the tech space in the past few years. From scale models, gifts and clothing to prosthetic limbs, hearing aids and the prospect of 3D-printed homes, the possibilities seem endless. The concept of 3D printing is by no means new, however. Chuck Hull invented and patented stereolithography (also known as solid imaging) in the mid-1980s, when he founded 3D Systems, Inc. Since then, advances in the technology have been (and continue to be) made, including the size of the printers themselves, the materials they can use and more.

The Battery Powered Home: A Global Transformation Is Under Way! (video) posted Categories: Energy In spite of the fact that millions of people around the world are looking to Solar Power as a solution to their utility expenses, different communities, cities, and counties have different rules about how to apply the power you produce to the local grid system, and at what cost they buy it back from you. As seen in the following video, all too often, when you overproduce power, you are paid 1/4 of the price you pay when you use their power, and net-metering is not fairly applied to production.
