3D Printing

3D PRINTING

A 3D printer cannot make any object on demand like the "Star Trek" replicators of science fiction. But a growing array of 3D printing machines has already begun to revolutionize the business of making things in the real world.

3D printers work by following a computer's digital instructions to "print" an object using materials such as plastic, ceramics and metal. The printing process involves building up an object one layer at a time until it's complete. For instance, some 3D printers squirt out a stream of heated, semi-liquid plastic that solidifies as the printer's head moves around to create the outline of each layer within the object. I got this from this site. If you’re just getting started you can try some of 3D modeling software which can be downloaded for free.

• Google SketchUp - This Google SketchUp is fun and free, and is known for being easy to use. To build models in SketchUp, you draw edges and faces using a few simple tools that you can learn in a short time. With with Push/Pull tool you can extrude any flat surface into a 3D form. Furthermore, it works together with Google Earth, that you can import a scaled aerial photograph directly from Google Earth, or use SketchUp to build models which can be seen in Google Earth.

• 3Dtin - The simplest 3D software. You can draw directly from your browser. 

• Blender - Blender is the free open source 3D content creation suite, available for all major operating systems under the GNU General Public License. Blender was developed as an in-house application by the Dutch animation studio NeoGeo and Not a Number Technologies (NaN). It is a powerful program contains features that are characteristic of high-end 3D software. 

• OpenSCAD - OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and Mac OS X. it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects.

• Tinkercad - Tinkercad is a new and faster way of creating designs for your 3D printer. With only three basic tools you can create a wide range of useful things. Once your project is ready simply download the STL file and start your 3D print.

Commercial software such as CAD software AutoCAD and Pro Engineer, software packages Rhino, Maya, and SolidWorks are all pretty good for designing 3D models. I got this from this site. Enthusiasm is high, and so is the market for 3D printing in both consumer and enterprise space. According to Gartner research, printers under $100,000 were expected to grow almost 50 percent in 2013, and will increase 75 percent this year. Right now, enterprises are using the printers to prototype objects, but we'll see an increasing amount used to make product designs this year. i got this from this site.
